COMPARATIVE ANALYSIS OF LEAD AND NON-LEAD BASED ORGANO-METALLIC HALIDE PEROVSKITE CELLS

Abstract

Perovskite solar cells (PSC) have attracted considerable attention recently due to their high energy conversion efficiency, low price, simple manufacturing process, with a conversion efficiency raised from 3.8% to 25.5%, and thus are a promising new generation photovoltaic technology. This article discusses the development of device structure, the creation of material deposition techniques, including complex device engineering strategies aimed at enhancing controls over the morphology, crystallinity, composition, as well as interface properties of perovskite thin films. This article is a comparative analysis of PSC, namely lead and lead-free PSC, in order to determine which PSC is more efficient and environmentally benign. We compared two types of perovskite solar cells: CH₃NH₃PbI₃ and CH₃NH₃PbI_3-xCl_x which are lead-based perovskite solar cells versus Cs₂TiBr₆ and MASnI₃ which are lead-free perovskite solar cells.
