Furan‐Substituted Phosphine‐Oxide as an Efficient Interfacial Modifier for Wide‐Bandgap Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
We report phosphine‐oxide interlayers for wide‐bandgap perovskite solar cells, in which tuned P = O Lewis basicity enables selective passivation of buried NiOx/perovskite interfaces and introduces interfacial dipoles that strengthen the built‐in field.
