This research work presents a lead-free, environment-friendly, tin-halide-based perovskite solar cell (PSC). In our research, we employed Cs₂SnI₆ as an absorber layer, which is coupled with several different inorganic electron transport layers (ETLs) and hole transport layers (HTLs) for experimental purposes. These various permutations of the device structure are simulated and optimized in the SCAPS-1D simulator to achieve the highest possible efficiency. In our work, we suggested the architecture of ZnO/Cs₂SnI₆/Cu₂O which is the most suitable for effective and long-lasting PSCs with exceptional device performance. In addition, we investigated and evaluated the impact of several parameters like HTLs, ETLs, absorber thicknesses, defect densities, operating temperature and series resistance over device performance. The proposed configuration displayed excellent power conversion efficiency (PCE) of 30.11% with 1.49$$V, 27.25 mA/cm² and 73.66% of open-circuit voltage ($V_{\mathrm{\text{OC}}})$, short-circuit current ($J_{\mathrm{\text{SC}}})$ and fill factor (FF), respectively, and is pertinent for lead-less, tin-halide-based PSCs in the future.
