Solar water splitting using metal–insulator–semiconductor junctions has proven efficient, but these junctions degrade very rapidly. Here, the authors engineer metal–insulator–semiconductor interfaces in which Fermi-level pinning is reduced, producing an efficient and durable photoanode for solar-driven water oxidation.
