英文摘要: In this paper, a new layered hybrid perovskite film ((EDA)(MA)(2)[Pb3I10]) was synthesized through one-step method. Ethylenediamine (EDA) cation was introduced into the perovskite lattice to synthesize a layered structure with improved resistance to degradation by humidity. The effects of humidity and time on crystal structure, composition, morphology and absorption spectra of (EDA)(MA)(2)[Pb3I10] were analyzed by in situ grazing incidence X-ray diffraction (GIXRD), scanning electron microscope (SEM), and UV-Vis spectroscope. The results reveal that a (EDA)(MA)(2)[Pb3I10] film is more moisture resistant than a CH3NH3PbI3 film which is widely used in the perovskite solar cell now. UV-Vis spectroscopy result also shows that the layered structure film is a suitable solar absorber with a bandgap (1.67 eV), which is close to the optimum value for solar photoelectric conversion. Compared to CH3NH3PbI3, the low-cost perovslcite structure offers greater tunability on a molecular level for further material optimization and possibility for widely used in the future.
