High-performance perovskite solar cells have demonstrated commercial viability, but still face the risk of contamination from lead leakage and long-term stability problems caused by defects. Here, an organic small molecule (octafluoro-1,6-hexanediol diacrylate) is introduced into film to form a polymer through in situ thermal crosslinking, which carbonyl group anchors uncoordinated Pb2+ reduces lead, along with -CF2 - hydrophobic protecting water invasion. Additionally, passivates varieties Pb-related I-related defects coordination hydrogen bonding interactions, regulating crystallization reduced trap density, releasing lattice strain, promoting carrier transport extraction. The optimal efficiencies polymer-incorporated devices are 24.76 % (0.09 cm2 ) 20.66 (14 ). More importantly, storage stability, operational been significantly improved.
