Solution fabrication methods and optimization strategies of CsPbBr3 perovskite solar cells

Abstract

In recent years, all-inorganic CsPbBr₃ perovskite solar cells (PSCs) have attracted tremendous attention due to their superb stability under thermal and moisture induction. Great efforts have been made to fabricate CsPbBr₃ PSCs with enhanced efficiency and stability. To date, the power conversion efficiency of CsPbBr₃ PSCs has steadily increased from the initial 5.95% to the current 11.08%, demonstrating attractive potential in the photovoltaic field. In this article, we briefly review the development and current status of CsPbBr₃ PSCs, summarize the solution preparation methods of CsPbBr₃ films, and analyze emphatically the optimization strategies of CsPbBr₃ PSCs. Finally, we discuss the potential applications and prospects of CsPbBr₃ PSCs.
