DuPont is putting its science to work to help transform the sun’s potential into clean, efficient energy the world needs to thrive. As a result, DuPont provides some of the world’s most innovative materials for photovoltaic (PV) solar cells and modules.In fact, DuPont materials have been at the forefront of innovations for more than three decades, setting new PV industry standards around the world. Today, our solutions are helping to significantly lower overall PV system coststo enable the industry to reach grid parity faster.We also believe in the power of collaboration. That’s why we work closely with others throughout the PV industry and develop technology partnerships to help create solar modules that run more efficiently, last longer and make solar energy a more viable alternative for everyone.Materials matter in PvFor solar power to become the long-term chosen renewable energy source globally, it must first reach grid parity and become cost competitive (without the aid of government subsidies) to other forms of electricity.For grid parity to be achieved, overall PV system costs must be reduced. Materials play a unique and critical role in making this happen—and DuPont products continueto lead the way. That’s why more than 70% of all solar modules ever made use DuPont materials.Our products help lower PV LCOE (levelized cost of energy) by impacting cell and module efficiency, lifetime and performance. Increased efficiency and extended lifetime result in improved power output over time, thereby reducing overall system cost. continuing innovationSince creating the first purified silicon for PV use morethan 55 years ago, DuPont has continued to revolutionizethe industry. Our innovation capability has led to the development of market-leading materials for cell metallization, module encapsulation, backsheet protection and other solar applications, helping to continuously improve the efficiency, lifetime/performance and cost of PV systems.This innovation is driven by our research and development labs located in North America, Europe and Asia.DuPont aggressively invests in materials innovations thatare designed to work together to help meet the industry’s cost-down roadmap. We also continue to invest in capacity expansions—to meet the need for new innovative solutions to support solar industry growth—and in the developmentof technologies—to address different applications withinthe industry.Looking forward, we see a rich set of new materials developments that will drive the industry to grid parityand beyond. DuPont will continue to play a critical roleby developing materials that deliver on the industry’shigh-efficiency crystalline silicon roadmap and enable robust, low-cost thin film technologies.The promise of tomorrow is becoming a reality today—powered by the solar innovations of DuPont.DuPont puts its science to work to offer the PV industry a broad product portfolio of solutions for traditional crystalline silicon and thin film modules.AB C B GFD FABC EB GFFrontsheet MaterialsLighter and less fragile than glass, durable DuPont frontsheet materials deliver high performance to help increase power output and offer more design options for BIPV applications.Photovoltaic EncapsulantsWith a broad portfolio of innovative solutions, DuPont encapsulation materials deliver long-term protection for the most sensitive portions of photovoltaic modules.Photovoltaic MetallizationsDuPont is raising the bar for PV cell metallizations.
