The present work represents the study of numerical simulation of Cesium Titanium (IV) Halide thin film based lead-free Perovskite Solar Cells (PSCs) using Solar Cell Capacitance Simulator (SCAPS). For this study, an alternative inorganic material cell architecture CuSCN/Cs2TiX6/CdS/Si has been proposed, where X is halide like Br, I, F and Cl. The effects of variation in absorbing layer thickness and device working temperature on the solar cell performance were simulated through SCAPS simulator. This simple cell architecture has helped us to study and optimize the device parameters. The 1D optimization for the proposed lead-free Perovskite based solar cell resulted in optimized active layers thickness, device temperature and quantum efficiency for Cs2TiBr6, Cs2TiI6, Cs2TiF6 and Cs2TiCl6 active materials. The study resulted in optimized thickness of 1.0 mu m, 1.5 mu m, 1.5 mu m and 1.5 mu m for Cs2TiBr6, Cs2TiI6, Cs2TiF6 and Cs2TiCl6 active materials, respectively. The optimized device temperature was found to be at 80 degrees C for Cs2TiBr6, 60 degrees C for Cs2TiI6, 75 degrees C for Cs2TiF6 and 75 degrees C for Cs2TiCl6.
