Optimizing Tin-based Solar Cells: Unleashing the Potential of CsSnI3 Perovskite for a Sustainable Energy Future

A sustainable and environmentally conscious future is provided by renewable energy sources, notably solar energy, which have become a crucial element of the global energy revolution. Tin (Sn)-based solar cells are thought to be a competitive challenger in the PV (photovoltaic) market. PV devices based on cesium tin triiodide (CsSnI
3
) material are still trailing in performance, and they have not yet attained high conversion efficiency. The influence of thickness variability has been researched to examine the effectiveness of the device. For all device simulations, SCAPS-1D is the simulation tool of choice. ITO/ PCBM(ETL)/ CsSnI

absorber's thickness in the suggested research ranges from 50 to 500 nm in 10 equal steps. After experimenting, the device's performance is optimized at 500 nm, which offers better PV, short circuit current (J
