翻译摘要	The invention provides a preparation method of a two-dimensional layered perovskite film based on hot air blowing. The preparation method comprises the following steps of : spreading a two-dimensional layered perovskite precursor solution on the surface of a substrate by using a drop coating method; and blowing the surface of the substrate by using hot air to obtain the two-dimensional layered perovskite film. The two-dimensional layered perovskite thin film prepared by the invention has compact micro-morphology, crystal orientation which grows perpendicular to the substrate and higher crystal phase purity, thereby having excellent photoelectric properties; Accordingly, the two-dimensional layered perovskite solar cell prepared based on the method of the invention exhibits excellent photoelectric conversion efficiency and stability. The method of the present invention is simple in operation and improves the efficiency of material use; The preparation method provided by the invention can be used for preparing the two-dimensional layered perovskite and the large-area uniform film which are insensitive to the humidity. in addition, the preparation method provided by the invention is suitable for preparing different types of high-quality two-dimensional perovskite films and corresponding high-performance solar cell devices.
