Numerical Analysis and Optimization of CH3NH3PbI3-xCIx Based Perovskite Solar Cells
Abstract
Due to unique properties of perovskite materials, the solar cells technologies based on those materials rapidly advance to the maximum theoretical conversion efficiency of about 32 %. This study reports the simulation results of CH3NH3PbI3-xCIx based perovskite solar cells using SCAPS-1D software. ZnO is used as common electron transfer medium (ETM), whereas Cu2O, CuI and CuO materials are separately used for hole transfer medium (HTM) each time. The cell basic parameters (Voc, Jsc, FF and efficiency) are simulated at various conditions. CuO is found to be the best HTM material, whereas the maximum efficiency of ̴26.8 % is obtained at 0.55 µm thickness of CH3NH3PbI3-xCIx material with a donor atom density of about 1017 cm-3.
