In‐Situ Solution Complexation for n‐Type Surface‐Energetics Reconstruction in 2.0 eV Ultra‐Wide‐Bandgap Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
A reactive in situ solution complexation strategy reconstructs the surface of 2.0 eV ultra‐wide‐bandgap perovskites via proton transfer. This chemical modulation eliminates metallic defects and induces a degenerate‐like n‐type surface, establishing an Ohmic tunneling contact.
