Tin based perovskite solar cell have gained the significant attention in recent year due to its potential to revolutionize the field of photovoltaic. The substitution of lead with tin in perovskite solar cells helps address the toxicity issues associated with lead based material. Formamidinium tin triiodide (FASnI3) had a more solid perovskite structure, wider bandgap of 1.41 eV and is more temperature stable than methylammonium tin triiodide (MASnI3). These are the reasons we chose FASnI3 in this study. In this work we simulated FASnI3 based perovskite solar cell using tungsten trioxide (WO3) as an electron transport material and cuprous oxide (Cu2O) as an hole transport material using SCAPS simulation. We investigated the impact of varying the thickness and doping concentration of different layer of PSC. Additionally, the effect of interface defect density and temperature dependence on device performance are examined. Further, various metal back contacts such as Au, Ag, Cu, Pt and Ni are investigated to enhance the power conversion efficiency (PCE) of final structure. The initial design was founded on an reported simulation that achieved the PCE of 14.03 %. The proposed solar cell structure has shown an efficiency of 23.44 % with a Jsc of 22.83 (mA/cm²), a Voc of 1.18 V, and a FF of 86.95 %. It is the highest reported efficiency of FASnI3 based perovskite solar cell using WO3 as an ETL till date. [ABSTRACT FROM AUTHOR] |
