Thermally Crosslinked F‐rich Polymer to Inhibit Lead Leakage for Sustainable Perovskite Solar Cells and Modules

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 the perovskite film...
