High Efficiency of Tandem Perovskite Solar Cells: Optical-Electrical-Thermal Simulation

The SCAPS-1D simulation tool was employed to conduct photoelectric simulation of perovskite solar cells in this paper. To begin with, a MAPbI 3 /MASnI 3 layer was used as the perovskite absorption layer to investigate the performance of tandem perovskite solar cells. The influence of defect density and the work function of the front electrode on the device performance were studied. Additionally, the impact of temperature variations on device performance was studied. The results indicate that the MAPbI 3 /MASnI 3 tandem perovskite solar cells achieve higher efficiency (30.05%) than the single-junction perovskite solar cells. Moreover, low defect density and temperature were found to be beneficial for higher performance. The heat distribution inside the device was studied using the finite element method. Furthermore, the influence of different hole transport materials and electron transport materials on the performance of perovskite solar cells with the hybrid perovskite layer (MAPbI 3 /MASnI 3 ) was investigated and find out the appropriate transport layer materials. This research provides a reference for the perovskite solar cells.
