Numerical study of Methylammonium Lead Iodide Perovskite solar cells using SCAPS-1D simulation program

Due to the high cost of experimenting and manufacturing solar cells, researchers have turned to numerical simulation. The optimization by simulation has the advantage of being easy, not costly, and we can predict the optimal parameters that contribute to the manufacture of a cell with the best performance. This work aims to simulate the essential properties of a perovskite solar cell. The solar cell capacitance simulator in one dimension has been carried out to design the proposed ITO/PEDOT: PSS/CH3NH3PbI3/ ZnO/SnO2: F and simulate its performance. The main idea behind this analysis is to study the variation of electrical parameters like Voc, Jsc, g and FF with the variation in materials parameters such as the perovskite absorber layer (CH3NH3PbI3) and the electron-transporting layer (ZnO). Thickness, series resistance and temperature, were varied to study the optimized performance. Simulations results using SCAPS-1D software show that the highest efficiency of the solar cell can be reached where the thicknesses of CH3NH3PbI3 and ZnO are 0.6 mm and 0.2 mm respectively, and for the optimal value of temperature equal to 300 K. A conversion efficiency of 20.2524 % along with a fill factor of FF = 94.684 %, a shortcircuit current density of Jsc = 25.595 mA/cm2, and an open-circuit voltage Voc = 0.835 V is obtained for the proposed structure.
