Enhancing UV Stability of Perovskite Solar Cells with Transparent Fluorinated Polyimide
Ultraviolet (UV)-induced degradation is one of the major problems in the field of perovskite solar cells (PSCs).Therefore, exploring materials and techniques to prevent UV light from penetrating into the device is urgently necessary.Here, we developed a special transparent fluorinated polyimide (FPI) resin, which can be directly spin-coated on the
