Design and simulation of a highly efficient eco-friendly, non-toxic perovskite solar cell

Abstract A highly efficient and nontoxic material methylammoniumtin(II) iodideperovskite solar cell is proposed. This proposed solar cell uses CH 3 NH 3 SnI 3 as the absorber layer, TiO 2 as an Electron transport layer (ETL), Indium tin oxide as a buffer layer, and Copper(I) oxide as the hole transport layer (HTL). The device is simulated using the SCAPS-1D simulation tool. This study details the optimization of a set of parameters, including the defect densities and the thickness of the absorber layer. The proposed structure is highly optimized result of 31.73% of enhanced power conversion efficiency (PCE), a J SC of 24.526 mA/cm 2 (short-circuit current), FF of 81.40% (fill factor), and a V OC of 1.56 V…
