Jianfei Hu1,2†, Qingbin Cai3†, Yuexin Lin4†, Yuanhui Xiao5†, Li Yang1,2,6*, Kun Wei1, Cuiping Zhang1, Xiaofeng Li1, Zhihan Liao1, Qingming Huang5, Yuanyuan Li1, Ye Yang5, Chao Liang4*, Jinbao Zhang1,2* Thermal annealing improves the crystallinity of perovskite films and boosts their power conversion efficiencies (PCEs) in solar cells but also induces surface iodine loss and local lattice degradation. We demonstrate a molecular press annealing (MPa) strategy in which a 2-pyridylethylamine film is thermally and pressure-bonded to the perovskite surface. real-time healing of iodine vacancies occurred during annealing and the lead-iodine framework was stabilized through optimized ligand engineering, resulting in enhanced structural integrity and long-term stability of perovskite films. …
