Theoretical and Experimental Investigation of All‐Inorganic CsPbIBr₂ Light‐Absorber‐Layer based Perovskite Solar Cells

Abstract

In last few years, rapid surge in the construction of perovskite or perovskite-like structures based photovoltaic cells have been noticed. Lead (Pb)-halide perovskite materials possess excellent optoelectronic features which make it most significant light absorber layer for the construction of CsPbIBr 2 based perovskite solar cells (PSCs). In particular, CsPbIBr 2 has unique optoelectronic properties and has been considered as a potential candidate for photovoltaic cells. In present work, we have used one-dimensional (1-D) solar cell capacitance simulator (SCAPS) to optimize the photovoltaic performance of CsPbIBr 2 based PSCs. The optimized simulated PSCs showed excellent efficiency of 14.11 %. Further, we have also fabricated PSCs which showed good efficiency of 10.18 %.
