Research progress in morphology control of perovskite thin films
Abstract
Inorganic-organic perovskite solar cells has been taken attention by researchers due to low price of liquid preparation methods and good photoelectric conversion performance. In recent years, the photoelectric conversion efficiency of perovskite solar cells has been increased from the beginning 3.8% to 22.1%, The module device efficiency is as high as 8.7%. is much higher than most other types of solar cells, because of its good optical absorption, high carrier mobility, and the band is adjustable and the variety of processing methods for modification. Based on the related research of photoelectric materials and further optimization of perovskite solar cells, the performance of the solar cells still have a high room for improvement. In this paper, based on the literature research, aimed to the development of perovskite materials used in solar cells, the preparation methods and influence factors of perovskite thin films are emphatically summarized. We also discussed the facing problems of future development and development prospects.
