More Information
Summary:The invention discloses a preparation method of an RP type two-dimensional perovskite thin film. The method comprises the following steps: mixing hydriodic acid and a solvent, adding an alicyclic amine compound into an ice-water bath, stirring, and removing the solvent to obtain organic spacer cations; the alicyclic amine compound is R-CH2-NH2, wherein R is selected from naphthenic bases containing 3 to 6 carbon atoms; the preparation method comprises the following steps: mixing organic spacer cations, formamidine hydriodate, methyl amine iodide and lead iodide according to a molar ratio of 2: 3.6: 0.4: 5, adding the mixture into a mixed solvent, and stirring to obtain a perovskite precursor solution; and preparing the RP type two-dimensional perovskite thin film from the perovskite precursor solution by adopting a solution spin-coating method. In addition, the invention further provides a perovskite solar cell, the photoelectric conversion efficiency of the perovskite solar cell can reach 16.70% at most, and
