Perovskite thin film preparation method and perovskite thin film product

The invention discloses a perovskite film preparation method and a product thereof, and the method comprises the steps: enabling a solution containing polymerizable zwitterionic gel to cover a substrate coated with a transmission layer, and then carrying out the illumination curing at room temperature, and obtaining a uniform gel interface layer; coating the upper part of the gel interface layer with a perovskite precursor liquid, and carrying out annealing treatment to obtain a compact and uniform perovskite thin film; according to the method, the defects of the bottom interface of the perovskite thin film can be obviously reduced, the non-radiation coincidence is reduced, the performance and stability of the perovskite solar cell are improved, the process is simple, the requirement for equipment is low, the stability and repetition rate are high, good universality is achieved, the dependence degree on the environment is low, and the cost is low. 本发明公开了一种钙钛矿薄膜制备方法及其产品，将含可聚合两性离子凝胶的溶液覆盖在涂覆有传输层的基底上，随后在室温条件下进行光照
