Simulation and analysis of effect of halide lons of perovskite-on- perovskite solar cells performance [Abstract]. In A.A.G.A.

In this study, the effect of Halide Ions of perovskite on PSCs performances were studied using solar cell capacitance simulator (SCAPS). Perovskite solar cells with MAPbI3 and PSCs with MAPbBr3 as the lightabsorbing materials have been simulated and compared the effect of the halide ion on solar cell performances. The efficiency of MAPbI3 and MAPbBr3 were reached 16.8% and 5.1% respectively. Also, the thickness of each MAPbI3 and MAPbBr3 was varied from 0.1 μm to 1.2 μm and the best results were observed at 0.5 μm and 0.4 μm thickness of MAPbI3 and MAPbBr3 films, respectively. A considerable effect of halide ions on PSC performances has been observed and it can be attributed to the variation of light absorption with the halide ions.enPerovskite solar cellsHalide ionsPerformancesThicknessConference-AbstractEngineeringDepartment of Materials Science and Engineering2021Materials Engineering Symposium on Innovations for Industry 2021Katubeddap. 18Innovative materials throughout mathematical modeling and simulationssewvangiga@yahoo.lk
