This study aims to explore the completion of perovskite solar cell technology with a large-area blade coating process. In this study, the structural transformation will be carried out, and the dual active layer will be added to the solar cell structure design and combined with the 2D/3D heterojunction. Using two-dimensional perovskite to reduce the surface defects of three-dimensional perovskite, it finally has excellent performance on solar cells, and the highest efficiency of 15.96% is achieved by the blade coating process in the high humidity atmospheric environment. The device with high stability, after 35 days still keeps the high performance above 15%.
