Amidination of Ligands for Chemical and Field-Effect Passivation Stabilizes Perovskite Solar Cells
Published in Science 2024, 386 (6724), 898–902, 2024
Amidination converts carboxylate surface ligands into amidine groups that provide simultaneous chemical passivation (bonding to Pb) and field-effect passivation (permanent dipole), stabilizing >25% efficient cells.
