Growth and Characterization of Hybrid Organolead Halide CH3NH3PbI3 Thin Films Prepared by Single Source Thermal Evaporation

doi:10.15541/jim20150098

Abstract

Abstract:

Hybrid organolead halide CH₃NH₃PbI₃ thin films were prepared by thermal evaporation with single source. The microstructure, composition, surface morphology and optical properties of the thin films were characterized by X-ray diffractometry (XRD), X-ray dispersive spectroscope (EDS), scanning electron microscope (SEM) and spectrophotometer technique, respectively. The comparison on properties for the films prepared by different methods (thermal evaporation and spin coating) was illustrated. Compared to the film prepared by spin coating, uniform, the nonporous and complete surface coverage perovskite thin film with high level of phase purity and good crystallization is formed by single source thermal evaporation. A direct bandgap of 1.57 eV for CH₃NH₃PbI₃ thin films is obtained which makes this material to be a good light absorber.

Key words: thermal evaporation, CH3NH3PbI3 thin films, perovskite solar cell, microstructure
