Passivating defects using organic halide salts, especially chlorides, is an effective method to improve power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) arising from the stronger Pb-Cl bonding than Pb-I and Pb-Br bonding. However, Cl- anions with a small radius are prone incorporation into lattice that distorts lead octahedron, degrading photovoltaic performance. Here, we substitute atomic-Cl-containing molecules for widely used ionic-Cl which not only retain efficient...

Abstract Synergistic morphology and defects management at the buried perovskite interface are challenging but crucial for further improvement of inverted solar cells (PerSCs). Herein, an amphoteric organic salt, 2‐(4‐fluorophenyl)ethylammonium‐4‐methyl benzenesulfonate (4FPEAPSA), is designed to optimize film energy level alignment interface. 4FPEAPSA treatment promotes growth a void‐free, coarse‐grained, hydrophobic by inducing crystal orientation. Besides, dual‐functional can chemically...
