The great demand for renewable energy has greatly contributed to the development of solar cell industry. Recently, silicon cells have dominated world market. ease processing gives perovskite (PSCs) an advantage over conventional cells. Regular photovoltaics require expensive, multi-step processes accomplished in a specialized ultraclean-chamber facility at elevated temperature (>1000 °C) and highly vacuumed workspace. Hence, researchers industry focused on PSC as rival Despite this, highest efficiency was obtained from lead-based PSC, which considerably high toxicity issue low stability related lead content, so research field pays attention lead-free In this digital simulation, tin-based paper, methylammonium tin iodide (MASnI3) with use cerium oxide (CeO x ) electron transporting layer (ETL) varying percentages oxygen, means different shallow donor densities (ND). optimum value thickness absorber (perovskite) made, current-voltage characteristics calculations were also best cell. Then improvement made by changing ND CeO , best-optimized parameters were: open circuit voltage (VOC) 0.92 V, short current density (JSC) 30.79 mA cm-2, power conversion (PCE) 17.77%, fill factor (FF) 62.86%.
