The photovoltaic devices based on perovskite have witnessed a rapid increase in performance and are moving towards commercialization due to their low-cost electricity production. In this simulation work, we studied the photovoltaic performance of solar cells based on methylammonium tin iodide (MASnI3) perovskite materials using the numerical simulation tool SCAPS-1D. The main objective is to improve the performance of this solar cell by determining the optimum properties for its operation. The influence of different key parameters, such as the thickness of the absorber layer and the doping acceptor density in the same layer, is thoroughly analyzed through SCAPS-1D. The optimized absorber layer with a thickness of 700 nm shows the highest power conversion efficiency of 26.21%. An increase in the doping density in the perovskite layer roughly increases the efficiency performance of the device to 30.21%. Based on our simulation results, it can be concluded that the TiO2/MASnI3/Spiro-OMeTAD structure for PSC is a potential alternative to the third generation of solar cells. It has the potential to be efficient and inexpensive in future research
