Recent trends in Lead-Free Inorganic Pervoskite solar cells: A Brief review

Abstract

There has been considerable increase in power conversion efficiency (PCE) of organic–inorganic hybrid perovskite solar cells (PSCs) in comparison with commercially available silicon solar cells.  The presence of organic compounds in perovskite solar cells has made them instable in air. This bottleneck came be overcome by fully replacing the A-site organic cations with pure inorganic. Recent research in this area has shown significant results and the PCE of inorganic lead-based PSCs has exceeded 17%. This review paper reveals the recent developments of inorganic PSCs and its future prospects.
