Organo-Lead Halide Perovskite Materials CH3NH3PbI2X, X is I, Br, or Cl, in Solar Cell Applications

Abstract

The optoelectronic response of organic perovskite solar cells (OPSCs) exhibits a variety of unique and distinguishing characteristics. In this study, OPSCs with photosensitizers, CH3NH3PbI2X, where X is I, Br, or Cl, are created using TiO2 as the electron transport material (ETM) and CuO as the hole transport material (HTM). The perovskite materials’ structural and optical characteristics, as well as the OPSCs’ ETM layers, are investigated. Next, the OPSC’s performance is evaluated. The integrated cell tester, which includes the I-V photovoltaic measurements system and the solar simulation system, was used to measure the I-V curves of the OPSCs. The photovoltaic devices with MAPbI3 as an efficient absorption layer had the best power conversion efficiency [Formula: see text]. Measurements of the OPSC’s performance were tested at 100[Formula: see text]mW/cm2 of light intensity.
