摘要

<正>In recent years, the development of wearable devices has a growing demand for flexible solar cells. Among them, improving the efficiency of the cells, enhancing the stability of device performance during bending and achieving self-repairing are important focuses of researchers. Perovskite materials have been found to be one of the new materials to improve the efficiency of flexible solar cells [1,2]. At present, the problem to be solved is the degradation of device performance during bending,
