Recent progress in the development of high-efficiency inverted perovskite solar cells

Abstract Perovskite solar cells (PSCs) have attracted much attention due to their low-cost fabrication and high power conversion efficiency (PCE). However, the long-term stability issues of PSCs remain a significant bottleneck impeding commercialization. Inverted with p-i-n architecture are being actively researched concurrent good decent efficiency. In particular, PCE inverted has improved significantly in recent years is now almost approaching that n-i-p PSCs. This review summarizes progress development high-efficiency PSCs, including perovskite compositions, methods, counter electrode materials (CEMs). Notably, we highlight charge transport (CTMs) effects defect passivation strategies on performance Finally, discuss remaining perspectives
