Abstract
Nowadays, methylammonium tin iodide \({{\text{MASnI}}}_{3}\) halide-based perovskite solar cells are engaging the research community, because of its unique properties like excellent light absorption, narrow band gap, etc. Until now, 7.1% highest power conversion efficiency (PCE) is reported for \({{\text{MASnI}}}_{3}\) perovskite solar cells (PSCs). The focus of the research is the design and analysis of lead-free tin-halide-based perovskite solar using SCAPS TCAD tool. Moreover, the proposed device is analyzed by consider some parameters such as absorber layer thickness, variations of different electron transport layer (ETL) and hole transport layer (HTL) and thickness variation of ETL and HTL. In this work, 12.76% highest power conversion efficiency is attained by the optimized device. Furthermore, the focused research work could be consider for climatic conditions analysis, fabrication opportunities and tandem applications.
