The lead-free perovskite solar cells (PSCs) have drawn much research interest due to the P_b toxicity of the lead halide perovskite. CH₃NH₃SnI₃ is a viable alternative to CH₃NH₃PbX₃. In this work, we designed a tin-based perovskite simulated model with the novel architecture of (TCO)/buffer (TiO₂)/absorber (Perovskite)/hole transport material (HTM) and analyzed using the solar cell capacitance simulator (SCAPS-1D), which is well adapted to study the photovoltaic architectures. In the paper, we studied the influences of perovskite thickness and the doping concentration on the solar cell performance through theoretical analysis and device simulation. The results are indicating that the lead-free CH₃NH₃SnI₃ is having the greatpotential to be an absorber layer with suitable inorganic hole transport materials like CuI (PCE: 23.25%), Cu
