Abstract

According to the recent remarkable developments of lead halide perovskite solar cells, investigation of the optical and electronical properties of perovskite structures seems necessary. In this paper, firstly Organic–inorganic CH₃NH₃PbX₃ perovskite hybrids with X= Cl, Br and I were prepared by solution chemistry method. The effect of halogen atom on the electronical properties in this structure was studied experimentally. Our study concludes that the band gap energy can be tuned by varying the halogen atoms. Thus we believe that our studies will be beneficial for the fabrication of electronic and optical devises.
