Problems solved by technology

[0003] With the rapid improvement of device efficiency, the poor moisture resistance of three-dimensional organic-inorganic hybrid perovskite materials has become the focus of attention from all parties. Poor moisture resistance can easily lead to device performance degradation, which in turn affects the life of the device. ; Moreover, the organic-inorganic hybrid perovskite quantum dots prepared by traditional methods still have complex packaging problems, which has become a major obstacle to the practical application of hybrid perovskite materials
