Enhancing the Performance of CsSnCl3-Based Perovskite Solar Cells Through SCAPS Simulation Optimization

Recently, there has been a lot of interest in the development and manufacturing of lead-free perovskite compounds for the fabrication of PSCs. A promising and effective absorption material for free-of-lead PSC is CsSnCl3 (Cesium tin chloride). This research paper focuses on investigating the effect of the thickness of CsSnCl3 layer on the PV (photovoltaic) parameters using the SCAPS tool. Perovskite solar cells (PSCs) are an obtainable device for creating renewable energy because of their greater efficiency and low manufacturing costs. The effect of thickness variance on device efficacy has been investigated. The suggested ITO/TiO2/CsSnCl3/Cu2O/Au device structure is developed. The thickness of the CsSnCl3 absorber in this suggested study ranges from 50 to 500 nm, with a bandgap of 1.52 eV. After altering the layer's thickness of the absorbing layer, the following PV measurements are displayed: PCE of 21.33%, VOC of 1.14 V, JSC of 24.58 mA/cm2, and FF of 85.75%.
