Zusammenfassung:The invention discloses an indium sulfide film and a preparation method thereof, and an inorganic perovskite solar cell based on the indium sulfide film and a preparation method thereof. The preparation method of the indium sulfide film comprises the following steps: mixing mercaptoacetic acid, ethylene glycol monomethyl ether and soluble salt of indium, and carrying out stirring to obtain an indium sulfide precursor solution; and carrying out heating to 80-120 DEG C, carrying out condensation reflux to obtain indium sulfide sol, and coating conductive glass with the indium sulfide sol to obtain the compact pinhole-free indium sulfide film. The method has the advantages of low preparation temperature, high production efficiency, controllable film morphology and thickness and the like, theobtained indium sulfide film is good in quality, compact, free of pinholes, high in electron mobility and good in stability, and the solar cell prepared from the indium sulfide film is better in output performance. 本发明公开了硫化铟薄
