Perovskite cell preparation method based on high-stability perovskite organic precursor solution

The invention discloses a perovskite cell preparation method based on a high-stability perovskite organic precursor solution. The perovskite material is prepared by adopting a two-step method, the perovskite thin film layer is prepared by coating the perovskite organic precursor solution on the inorganic halide thin film layer, and the method is suitable for preparation of a formal-structure perovskite solar cell and a trans-structure perovskite solar cell. According to the method, the stability of the perovskite organic precursor solution is improved by regulating and controlling the perovskite organic precursor solution, the service life of the perovskite organic precursor solution is prolonged, and the prepared cell has excellent photoelectric conversion efficiency; according to the invention, the development of a two-step perovskite thin film preparation process is improved, and a new thought is provided for commercialization of perovskite solar cells. 本发明公开一种基于高稳定性钙钛矿有机前驱体溶液的钙钛矿电池制备方法。采用两步法制备钙钛矿材料，通过在无机卤
