摘要：
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. ©, 2015, Science Press. All right reserved.
