Abstract

The invention discloses a preparation method of inorganic perovskite solar cell with indium sulfide thin film and a product thereof. The preparation method of the inorganic perovskite solar cell disclosed by the invention has the advantages of low preparation temperature, convenient and simple preparation conditions, no annealing and the like, so that the inorganic perovskite solar cell can be directly prepared on a flexible substrate, thereby preparing a solar cell with high photoelectric conversion efficiency. The solar cell prepared by the invention comprises a transparent conductive FTO base layer, an In2S3 electron transport layer, a CsPbIBr2 perovskite light absorbing layer, a Spiro- An OMeTAD hole transport lay and a metal back electrode, As that electron transport lay, In2S3 is helpful to form the high quality perovskite absorbing lay, and the conduction band of the In2S3 electron transport layer is close to that of the CsPbIBr2 perovskite absorbing layer, which can reduce theopen-circuit voltage los of the solar cell to a certain extent, thereby improving the photoelectric conversion efficiency of the solar cell.

Description
