Numerical Study of Opto-Electrical Properties of a Mixed Halide Methylammonium Lead Halide (MAPbBr3-nIn; n=0, 1, 2 and 3) Based Perovskite Solar Cell

Abstract

In This research article represents the study of optical, and electrical properties of Methylammonium lead (MAPbBr3-nIn; n=0, 1, 2 and 3) (CH3NH3PbI3, CH3NH3PbI2Br, CH3NH3PbIBr2, and CH3NH3PbBr3) based Perovskite solar cell. An FTO/TiO2/ MAPbBr3-nIn/Spiro-OMeTAD/Al based structure with TiO2 as electron transport layer and Spiro-OMeTAD hole transport layer has been used for this study. The opto-electrical properties such as resonance time period, indirect and direct band gap have been studied. The results shows that the resonance time period, indirect band gap, and direct band gap for each of the Perovskite layer CH3NH3PbI3 is 9.09 µs, 1.4 eV and 2.6 eV, for CH3NH3PbI2Br is 6.25 µs, 1.5 eV and 2.7 eV, for CH3NH3PbIBr2 is 6.25 µs, 1.7 eV, and 2.8 eV and for CH3NH3PbBr3 is 5.55 µs, 2.1 eV and 2.9 eV respectively.
