The application discloses a flexible perovskite solar cell based on an in-situ cross-linking organic small molecule and a preparation method thereof, realizes synchronization of a cross-linking process and a perovskite growth process, thereby achieving the effect of small molecule in-situ cross-linking regulation of perovskite crystallization, and can simply prepare a high-efficiency and mechanically stable flexible perovskite solar cell. Based on the in-situ cross-linking strategy, the perovskite thin film growth greatly reduces the dependence on a flexible conductive substrate through a simple doping method, and a perovskite thin film with high crystalline quality, large grain size and low defect density is obtained on the flexible conductive substrate. Based on the perovskite thin film, not only a high-efficiency flexible perovskite solar cell can be prepared, but also the preparation of a large-area flexible device is applicable. In addition, the organic small molecule is aggregated at a perovskite grain boundary after in-situ cross-linking, effectively releases mechanical stress in the bending process, and reduces the Young's modulus of the perovskite thin film, so that the obtained flexible device has excellent mechanical stability.
