The invention belongs to the field of perovskite solar cells, and in particular relates to an anion and cation co-doped inorganic perovskite thin film and a preparation method and application thereof. The molecular formula of the thin film is MX:CsPbI (3‑x) Br x , wherein the doping concentration of MX is 0.125-0.5%, and the inorganic perovskite solar cell includes, from bottom to top, transparent conductive glass, hole transport layer , the above-mentioned perovskite layer, non-organic electron transport layer and metal electrode. The inorganic perovskite thin film prepared by co-doping with anions and cations in the present invention has no impurity phase, has a purer phase, and has more excellent air stability. The solar cell of the present invention has more excellent photovoltaic performance, and the device structure without the organic layer electron transport layer can greatly improve the thermal stability of the overall device of the cell. |
