Comparative Studies on the Efficiency, Reproducibility and Stability of Perovskite Solar Cells

2019    Kirbiyik, Cisem; Kus, Mahmut

In literature, many studies based on planar inverted structure using either CH3NH3PbI3 and CH3NH3PbI3-xClx perovskite absorbers have reported as high-efficiency solid-state perovskite solar cells. This study includes the comparison of photovoltaic characterizations, reproducibility and stability results of solar cells fabricated by using CH3NH3PbI3 and CH3NH3PbI3-xClx perovskite compounds. Herein, the results showed that CH3NH3PbI3 perovskite solar cells gave a lower photovoltaic performance as-fabricated when compared with CH3NH3PbI3-xClx perovskite solar cells. However, after 24 hours, CH3NH3PbI3 perovskite compound showed a higher photovoltaic performance and better time stability in inert atmosphere and more reproducible results. (C) 2019 Elsevier Ltd.
