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. …
