2015职称英语理工类A级真题(阅读理解)

2015职称英语理工类A级真题(阅读理解) 第4部分：阅读理解(第31—45题，每题3分，共45分)下面有3篇短文，每篇短文后有5道题。

请根据短文内容，为每题确定1个最佳选项。

第一篇Face Masks May Not Protect from Super-Flu IF a super-flu strikes, face masks may not protect you. Whether widespread use of masks will help, or harm, during the next worldwide flu outbreak is a question that researchers are studying furiously. No results have come from their mask research yet. However, the government says people should consider wearing them in certain situations anyway, just in case.But it’s a question the public keeps asking while the government are making preparations for the next flu pandemic. So the Centers for Disease Control and Prevention (CDC) came up with preliminary guidelines. “We don’t want people wearing them everywhere,” said the CDC. “The overall recommendation really is to avoid exposure.”When that’s not possible, the guidelines say to consider wearing a simple surgical mask if you are in one of the three following situations. First, you’re healthy and can’t avoid going to a crowded place. Second t you’re sick and think you may have close contact with the healthy, such as a family member checking onyou. Third, you live with someone who’s sick and thus might be in the early stages of infection, but still need to go out.Influenza pandemics can strike when the easy-to-mutate flu virus shifts to a strain that people never have experienced. Scientists cannot predict when the next pandemic will arrive, although concern is rising that the Asian bird flu might trigger one if it starts spreading easily from person to person.During the flu pandemic, you should protect yourself. Avoid crowds, and avoid close contact with the sick unless you must care for someone. Why aren’t masks added to this self-protection list? Because they can help trap virus-laden droplets flying through the air with a cough or sneeze. Simple surgical masks only filter the larger droplets. Besides, the CDC is afraid masks may create a false sense of security. Perhaps someone who should have stayed home would don an ill-fitting mask and hop on the subway instead.Nor does flu only spread through the air. Say someone covers a sneeze with his or her hand, then touches a doorknob or subway pole. If you touch that spot next and then put germy hands on your nose or mouth, you’ve been exposed. It’s harder to rub your nose while wearing a mask and so your face may get pretty sweaty under masks. You reach under to wipe that sweat, and may transfer germs caught on the outside of the mask straight to the nose. These are the problems face masks may create for their users.Whether people should or should not use face masks still remains a question. The general public has to wait patiently for the results of the mask research scientists are still doing.31. What is the passage mainly about?A. Widespread use of face masks.B. Possibility of a worldwide flu outbreakC. New discoveries of a face mask research.D. Effectiveness of wearing face masks32. The CDC suggests that peopleA. stay alone when being sick.B. wear face masks when going to a crowded place.C. wear face masks wherever possible.D. remain at home if living with someone who’s sick.33. The word "that" in Paragraph 3 refers toA. making preparations.B. avoiding exposureC. coming up with guidelines.D. wearing face masks everywhere.34. Which of the following statements is true?A. Scientists warn the next flu is coming soon.B. Asian bird flu is spreading easily from person to person.C. Masks protect people because they keep viruses away.D. Masks are not effective if a flu strikes.35. One of the concerns the CDC has is thatA .masks may give people a wrong assumption of being safe.B. the sick may not wear masks and go out.C. flu virus may spread via public transportation.D. healthy people may not know how to protect themselves.第二篇What’s killing the BatsFirst it was bees. Now it is bats. Biologists in America are working hard to discover the cause of the mysterious deaths of tens of thousands of bats in the northeastern part of the country. Most of the bats affected are the common little brown bats (Myotis lucifugus,) but other species, such as the long-eared bat, the small-footed hat, the eastern pipistrelle, and the Indiana bat have also been affected. In some caves, more than 90 percent of the bat populations have died.One possibility is disease. A white fungus (真菌)known as fusarium has been found on the noses of both living and dead bats. However, scientists don't know Ifthe fungus is the primary cause of death, a secondary cause of death, or not a cause at all, but the result of some other conditions.Another possible cause is a lack of food. For example, bats typically eat a large number of moths (蛾), and in some states such as New York, the number of moths has been declining in recent years. If bats can’t eat eno ugh food, they starve to death.Still other scientists believe that global warming is to blame. Warmer temperatures in recent years have been waking up hibernating (冬眠)bats earlier than usual. If bats break their hibernation at the wrong time, they might not find their expected food sources. The weather might also turn cold again and weaken or kill the bats.Scientists might not agree on the causes of the bat die-off, but they do agree on the consequences. Bats are an important predator of mosquitoes; a single brown bat can eat 1,000 or more insects in an hour. They also eat beetles and other insects that damage plant crops. If there aren't enough bats, damage will be great from the insects they eat While bats live a long time for their size 一the little brown bat can live for more than 30 years 一a female bat has only one baby per year, so bat populations grow slowly. Many bat species in the United States are already protected or endangered.How can you help? Do not disturb sleeping or nesting bats. If you discover bate that seem to be sick or that are dead, contact your local Fish& Wildlife Department with the details. However, be careful not to touch the animals.36. What is the main idea of this passage?A. All species of bats in North America are dying.B. Scientists already know the cause of the deaths of batsC. The bat deaths are a serious problem.D. There are many possible causes of the deaths of bats.37. What does the first sentence in Paragraph 1 mean?A. Bees have been dying mysteriously.B. The first article on the website is about bees.C. Bees usually die before bats.D. It was bees that caused the deaths of bats.38. The word “pipistrelle" in Parag raph 1 refers toA. a kind of fungus.B. an area in the U.S.C. a special cave.D. a kind of bat.39. The "moths" in Paragraph 3 are taken as an example ofA. diseases that kill bats.B. Insects that bats eat.C. animals that have diseases.D. bat species that are starving to death.40. What is the purpose of the last paragraph?A. To get people to stop killing bats.B. To hire workers for the Fish & Wildlife Department.C. To ask people not to touch dead bats.D. To tell the public how to help bats.第三篇Better Solar Energy Systems: More Heat, More Light Solar photovoltaic thermal energy systems, or PVTs, generate both heat and electricity, but until now they haven’t been very good at the heat-generating part compared to a stand-alone solar t hermal collector. That’s because they operate at low temperatures to cool crystalline silicon solar cells, which lets the silicon generate more electricity but isn’t a very efficient way to gather heat.That’s a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And it’s also a space problem：photovoltaic cells can take up all the space on the roof, leaving little room for thermal applications.In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has devised a solution in the form of a better PVT made with adifferent kind of silicon. His research collaborators are Kunal Girotra from ThinSilicon in California and Michael P athak and Stephen Harrison from Queen’s University, Canada.Most solar panels are made with crystalline silicon，but you can also make solar cells out of amorphous silicon, commonly known as thin-film silicon. They don’t create as much electricity, but t hey are lighter, flexible, and cheaper. And, because they require much less silicon, they have a greener footprint. Unfortunately，thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.“That mean s that their efficiency drops when you expose them to light —pretty much the worst possible effect for a solar cell,” Pearce explains，which is one of the reasons thin-film solar panels make up only a small fraction of the market.However, Pearce and his team found a way to engineer around the Staebler-Wronski effect by incorporating thin-film silicon in a new type of PVT. You don’t have to cool down thin-film silicon to make it work. In fact，Pearce’s group discovered that by heating it to solar-thermal operating temperatures，near the boiling point of water, they could make thicker cells that largely overcame the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solarthermal energy collector, they also found that by baking the cell once a day，they boosted the solar cell’s electrical efficiency by over 10 percent.41. PVTs are not efficient inA. creating electricity.B. cooling silicon solar cells.C. generating heat.D. powering solar thermal collectors.42. One of the problems PVTs have is thatA. their thermal applications are costly.B. they are too expensive to afford.C. they occupy too much space.D. it is hard to fix them on the roof.43. Which of the following is NOT mentioned as an advantage of thin-film silicon solar cells?A. They are electrically efficient.B. They are less expensive.C. They are flexible.D. They are environment friendly.44. Thin-film solar panels do not sell well on market becauseA. their advantages are not well-recognized.B. they do not work well if exposed to light.C. they need improving in appearance.D. they are not advertised.45 Which of the following statements is true?A. Thin-film silicon's electrical efficiency improves when heated up.B. New techniques have been developed to produce thin-film silicon.C. Thin-film silicon works efficiently at low temperature.D. A new material enlarging the Staebler-WronsKi effect has been created. 更多职称英语考试免费资料请访问“新东方在线职称英语频道”。

Animals began to prosper at the end of the Proterozoic period, about 800 million years ago — but what about the billion-year stretch before that, when most researchers think there also was plenty of oxygen?Well, it seems the air wasn’t so great then, after all.In a study published Oct. 31 in Science, Yale researcher Noah Planavsky and his colleagues found that oxygen levels during the “boring billion” periodwere only 0.1% of what they are today. In other words, Earth’s atmosphere couldn’t have supported a diver sity of creatures, no matter what genetic advancements were poised to occur.“There is no question that genetic and ecological innovation mustultimately be behind the rise of animals, but it is equally unavoidable that animals need a certain level of o xygen,” said Planavsky, co-lead author of the research along with Christopher Reinhard of the Georgia Institute of Technology. “We’re providing the first evidence that oxygen levels were low enough during this period to potentially prevent the rise of anim als.”The scientists found their evidence by analyzing chromium (Cr) isotopes in ancient sediments from China, Australia, Canada, and the United States. Chromium is found in the Earth’s continental crust, and chromium oxidation is directly linked to the presence of free oxygen in the atmosphere.Specifically, the team studied samples deposited in shallow, iron-richocean areas, near the shore. They compared their data with other samples taken from younger locales known to have higher levels of oxygen.Oxygen’s role in controlling the first appearance of animals has long vexed scientists.“We were missing the right approach until now,” Planavsky said. “Chromium gaveus the proxy.” Previous estimates put the oxygen level at 40% of today’s conditions during pre-animal times, leaving open thepossibility that oxygen was already plentiful enough to support animal life.In the new study, the researchers acknowledged that oxygen levels were “highly dynamic” in the early atmosphere, with the potential for occasional spikes. However, they said, “It seems clear that there is a first-order difference inthe nature of Earth surface Cr cycling” before and after the rise of animals.“If we are right, our results will really change how people view theorigins of animals and other complex life, and their relationships to the co-evolving environment,” said co-author Tim Lyons of the University ofCalifornia-Riverside. “This could be agame changer.”Funding sources for the research included the NASA Exobiology Program andthe National Science Foundation’s Earth-Life Transitions program, awarded to Planavsky, Reinhard, and Lyons.Theo ther members of the research team included Xiangli Wang, apostdoctoral fellow at Yale; Thomas Johnson, of the University of Illinois; Danielle Thomson, of Carleton University; Peter McGoldrick, of the Universityof Tasmania; and Woodward Fischer, of the California Institute of Technology. 16.The study discovered the rise of animals occurred earlier than the Proterozoicperiod.A.

Dartmouth researchers and their colleagues have created an artificial1,software that uses photos to locate documents on the Internet with far grejthan ever before.2.The new system, which was tested on photos and is now being applied to, I shows for the first time that a machine learning algorithm (运算法则)or,ma9e I recognition and retrieval is accurate and efficient enough toimprove large seaie, document searches online. The system uses pixel (像素)data in images and potentiay video — rather than just text — to locate documents. It learns to recognize the pixels associated with a search phrase by studying the results from text-based image search engines. The knowledge leaned (收集) from those results can then be applied to other photos without tags or captions making for more accurate document search results.3."Over the last 30 years," says Associate Professor Lorenzo Torresani, a co-author of the study," the Web has evolved from a small collection of mostlytext documents to a modern, massive, fast-growing multimedia dataset, where nearly every page includes multiple pictures or videos. When a person looks at a Web page, he immediately gets the gist (主旨)of it by looking at the pictures in it. Yet, surprisingly, all existing popular search engines, such as Google or Bing, strip away the information contained in the photos and use exclusively the text of Web pages to perform the document retrieval. Our study is the first to show that modern machine vision systems are accurate and efficient enough to make effective use of the information contained in image pixels to improve document search."4.The researchers designed and tested a machine vision system — a type of artificial intelligence that allows computers to learn without being explicitly programmed — that extracts semantic (语义的) information from the pixels of photos in Web pages. This information is used to enrich the description of the HTML page used by search engines for document retrieval. There searchers tested their approach using more than 600 search queries (查询)on a database of 50 million Web pages. They selected the text-retheval search engine with the best performance and modified it to make use of the additional semantic information extracted by their method from the pictures of the Webpages. They found that this produced a 30 percent improvement in precision over the original search engine purely based on text.23. Paragraph 1 __B__24. Paragraph 2 __C__25. Paragraph 3 __E__26.

2015职称英语理工类A级试题及答案讲解

2015职称英语理工类A级试题及答案职称英语考试《理工类A级》阅读理解强化练习题(5)Early or Later Day CareThe British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive “attachment” period from birth to three may scar a child's personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion.Firstly, anthropologists point out that the insulated love affair between children and parents found in modern societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, the father and mother of a child did not rear their infant alone —far from it. Secondly, common sense tells US that day care would not be so widespread today if parents, care-takers found children had problems with it. Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial. Thirdly, in the last decade there have been a number of careful American studies of children in day care, and they have uniformly reported that day care had a neural or slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.But Bowlby's analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cuff, though experience and available evidence indicate that early care is reasonable for infants.词汇：psychoanalyst n.精神分析学家一心理分析学家 insulate vt.隔绝rear vt.抚养 predispose 易导致 care taker n.照顾者，看管人 entail vt.蕴涵infant n.婴儿 anthropologist n.人类学家1.Which of the following statements would Bowlby support?A) Statistical studies should be carried out to assess the positive effect of day car for children at the age of three or older.B) Early day care can delay the occurrence of mental illness in children.C) The first three years of one's life is extremely important to the later development of personality.D) Children under three get used to the life at nursery schools more readily than children over three.2.Which of the following is derivable from Bowlby's work?A) Mothers should not send their children to day care centers before the age of three.B) Day care nurseries have positive effects on a child's development.C) A child sent to a day care center before the age of three may have emotional problems in later life.D) Baby care would not be so popular if it has noticeable negative effects on a child's s personality.3.It is suggested that modern societies differ from traditional societies in that ______ .A) the parents-child relationship is more exclusive in modern societiesB) a child more often grows up with his/her brothers or sisters in traditional societiesC) mother brings up children with the help of her husband in traditional societiesD) children in modern societies are more likely to develop mental illness in later years4.Which of the following statements is NOT an argument against Bowlby's theory?A) Many studies show that day care has a positive effect on children's development.B) The fact that there are so many nursery schools today shows that day care is safe.C) The separation of young children from their parents is common in some traditional societies.D) Parents find the immediate effects of early day care difficult to deal with.5. Which of the following best expresses the writer's attitude towards early day care?A) Children under three should stay with their parents.B) Early day care has positive effects on children's development.C) The issue is controversial and its settlement calls for the use of statistics.D) The effects of early day care on children are exaggerated and parents should ignore the issue.「答案解析」1.C 波比认为，孩子从出生到三岁这段时间是一个敏感的“依恋”期。

Green roofs are the most prevalent（流行）in Germany，which is widely regarded as the leader in green roof research.The green roofs that are used these days can be classified as 'extensive' and'intensive' systems. Extensive green roofs use mosses，grasses and herbs，which are tolerant to droughts.

In contrast, a wide range of species of plants are grown on intensive green roofs，such as shrubs（灌木）and even trees，which require deeper substrate layers，and are usually grown on flat roofs. They need intensive maintenance, and are usually areas that resemble parks which are accessible to people.There are several benefits of adopting green roof technologies.

2015年职称英语考试《理工A》真题Lackof Oxygen Delayed the Rise of Animals on EarthScientistshave long speculated as to why animal species didn‟t flourish sooner, oncesufficient oxygen covered the Earth‟s surface. Animals began to prosper at theend of the Proterozoi c period, about 800 million years ago —but what about thebillion-year stretch before that, when most researchers think there also wasplenty of oxygen?Well,it seems the air wasn‟t so great then, after all.Ina study published Oct. 31 in Science, Yale researcher Noah Planavsky and hiscolleagues found that oxygen levels during the “boring billion” period wereonly 0.1% of what they are today. In other words, Earth‟s atmosphere couldn‟thave supported a diversity of creatures, no matter what genetic advance mentswere poised to occur.“There is no questionthat genetic and ecological innovation must ultimately be behind the rise ofanimals, but it is equally unavoidable that animals need a certain level ofoxygen,” said Planavsky, co-lead author of the research along with ChristopherRein hard of the Georgia Institute of Technology. “We‟re providing the firstevidence that oxygen levels were low enough during this period to potentiallyprevent the rise of animals.”Thescientists found their evidence by analyzing chromium (Cr) isotopes in ancientsediments from China, Australia, Canada, and the United States. Chromium isfound in the Earth‟s continental crust, and chromium oxidation is directlylinked to the presence of free oxygen in the atmosphere.Specifically,the team studied samples deposited in shallow, iron-rich ocean areas, near theshore. They compared their data with other samples taken from younger localesknown to have higher levels of oxygen.Oxygen‟srole in controlling the first appearance of animals has long vexed scientists.“We were missing the right approach until now,” Planavsky said. “Chromium gaveus the proxy.” Previous estimates put the oxygen level at 40% of today‟sconditions during pre-animal times, leaving open the possibility that oxygenwas already plentiful enough to support animal life.Inthe new study, the researchers acknowledged that oxygen levels were “highlydynamic” in the early atmosphere, with the potential for occasional spikes.However, they said, “It seems clear that there is a first-order difference inthe nature of Earth surfa ce Cr cycling” before and after the rise of animals.“If we are right, ourresults will really change how people view the origins of animals and othercomplex life, and their relationships to the co-evolving environment,” saidco-author Tim Lyons of the University of California-Riverside. “This could be agame changer.”Fundingsources for the research included the NASA Exobiology Program and the NationalScience Foundation‟s Earth-Life Transitions program, awarded to Planavsky,Reinhard, and Lyons.Theother members of the research team included Xiangli Wang, a postdoctoral fellowat Yale; ThomasJohnson, of the University of Illinois; Danielle Thomson, ofCarleton University; Peter McGoldrick, of the University of Tasmania; andWoodward Fischer, of the California Institute of Technology.16.The study discovered the rise of animals occurred earlier than the Proterozoicperiod.A.RightB.

第2部分阅读判断Lackof Oxygen Delayed the Rise of Animals on EarthScientistshave long speculated as to why animal species didn’t flourish sooner, oncesufficient oxygen covered the Earth’s surface. Animals began to prosper at theend of the Proterozoic period, about 800 million years ago —but what about thebillion-year stretch before that, when most researchers think there also wasplenty of oxygen?Well,it seems the air wasn’t so great then, after all.Ina study published Oct. 31 in Science, Yale researcher Noah Planavsky and hiscolleagues found that oxygen levels during the “boring billion”period wereonly 0.1% of what they are today. In other words, Earth’s atmosphere couldn’thave supported a diversity of creatures, no matter what genetic advancementswere poised to occur.“There is no questionthat genetic and ecological innovation must ultimately be behind the rise ofanimals, but it is equally unavoidable that animals need a certain level ofoxygen,”said Planavsky, co-lead author of the research along with ChristopherReinhard of the Georgia Institute of Technology. “We’re providing the firstevidence that oxygen levels were low enough during this period to potentiallyprevent the rise of animals.”Thescientists found their evidence by analyzing chromium (Cr) isotopes in ancientsediments from China, Australia, Canada, and the United States. Chromium isfound in the Earth’s continental crust, and chromium oxidation is directlylinked to the presence of free oxygen in the atmosphere.Specifically,the team studied samples deposited in shallow, iron-rich ocean areas, near theshore. They compared their data with other samples taken from younger localesknown to have higher levels of oxygen.Oxygen’srole in controlling the first appearance of animals has long vexed scientists.“We were missing the right approach until now,”Planavsky said. “Chromium gaveus the proxy.”Previous estimates put the oxygen level at 40% of today’sconditions during pre-animal times, leaving open the possibility that oxygenwas already plentiful enough to support animal life.Inthe new study, the researchers acknowledged that oxygen levels were “highlydynamic”inthe early atmosphere, with the potential for occasional spikes.However, they said, “It seems clear that there is a first-order difference inthe nature of Earth surface Cr cycling”before and after the rise of animals.“If we are right, ourresults will really change how people view the origins of animals and othercomplex life, and their relationships to the co-evolving environment,”saidco-author Tim Lyons of the University of California-Riverside. “This could be agame changer.”Fundingsources for the research included the NASA Exobiology Program and the NationalScience Foundation’s Earth-Life Transitions program, awarded to Planavsky,Reinhard, and Lyons.Theother members of the research team included Xiangli Wang, a postdoctoral fellowat Yale; Thomas Johnson, of the University of Illinois; Danielle Thomson, ofCarleton University; Peter McGoldrick, of the University of Tasmania; andWoodward Fischer, of the California Institute of Technology.16.The study discovered the rise of animals occurred earlier than the Proterozoicperiod.A.RightB.

The system uses pixel (像素)data in images and potentia y video —rather than just text —to locatedocuments. It learns to recognize the pixels associated with a search phrase bystudying the results from text-basedimage search engines. The knowledgegleaned (收集) from those results can then beapplied to other photos without tags or captions making for more accuratedocument search results.3."Over the last 30 years," says Associate Professor Lorenzo Torresani,a co-author of the study, "the Web has evolved from a small collection ofmostly text documents to a modern, massive, fast-growing multimedia dataset,where nearly every page includes multiple pictures or videos. When a personlooks at a Web page, he immediately gets the gist (主旨)of it by looking at the pictures in it. Yet, surprisingly, all existing popularsearch engines, such as Google or Bing, strip away the information contained inthe photos and use exclusively the text of Web pages to perform the documentretrieval. Our study is the first to show that modern machine vision systemsare accurate and efficient enough to make effective use of the informationcontained in image pixels to improve document search."4.The researchers designed and tested a machine vision system — a type ofartificial intelligence that allows computers to learn without being explicitlyprogrammed —that extracts semantic (语义的) information from thepixels of photos in Web pages. This information is used to enrich thedescription of the HTML page used by search engines for document retrieval. Theresearchers tested their approach using more than 600 search queries (查询)on a database of 50 million Web pages. They selected the text-retheval searchengine with the best performance and modified it to make use of the additionalsemantic information extracted by their method from the pictures of the Webpages. They found that this produced a 30 percent improvement in precision overthe original search engine purely based on text.23. Paragraph 1 __B__24. Paragraph 2 __C__25. Paragraph 3 __E__26.

That’s because they operate at low temperatures to cool crystalline silicon solarcells, which lets the silicon generate more electricity but isn’ta very efficient way to gather heat.That’s a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And it’s also a space problem: photovoltaic cells can take up all the space on the roof, leaving little room for thermal applications.In a pair of studies, Joshua Pearce, anassociate professor of materials science and engineering, has devised a solution in the form of a better PVT made with a different kind of silicon. His research collaborators are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen’s University, Canada.Most solar panels are made with crystalline silicon, but you can also make solar cells out of amorphous silicon, commonly known as thin-film silicon. They don’t create as much electricity, but they are lighter, flexible, and cheaper. And, because they require much less silicon,they have a greener footprint. Unfortunately, thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.“That means that their efficiency drops when you expose them to light—pretty much the worst possible effect for a solar cell,”Pearce explains,which is one of the reasons thin-film solar panels make up only a small fraction of the market.However, Pearce and his team found a way to engineer around the Staebler-Wronski effect by incorporating thin-film siliconin a new type of PVT. You don’t have to cool down thin-film silicon to make it work. In fact, Pearce’s group discovered that by heating it to solar-thermal operating temperatures, near the boiling point of water, they could make thicker cells that largely overcame the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solar thermal energy collector,they also found that by baking the cell once a day, they boosted the solar cell’s electrical efficiency by over 10 percent.31.
