Abstract

Abstract: Hybrid perovskite solar cells (PSCs) are in existence in the field of photovoltaic technology since 2009 and they have achieved a major improvement in power conversion efficiency (PCE) from just 3.8% in 2009 to 25.2% in 2019. However, they do not last long due to the instability of hybrid perovskites caused by humid conditions and temperature. The stability issue of PSC can be resolved using cesium lead bromide (CsPbBr3 ) inorganic perovskite. CsPbBr3 perovskite has well resistant towards moisture and heat which provides better operational stability to the inorganic PSCs. These PSCs are easy to fabricate unlike silicon solar cells but, these PSCs are still not in commercial use as the hybrid PSCs have a limited lifetime and the inorganic PSCs have limited PCE. In this review article, we discuss the CsPbBr3 inorganic perovskite, its fabrication processes, properties, device configurations, and recent advancements. Moreover, here the alternatives of lead (Pb) to develop a non-toxic perovskite are also discussed.
