Enhanced Photoelectrochemical Activity in All‐Oxide Heterojunction Devices Based on Correlated “Metallic” Oxides

n-n Schottky, n-n ohmic, and p-n Schottky heterojunctions based on TiO2/correlated “metallic” oxide couples exhibit strong solar-light absorption driven by the unique electronic structure of the “metallic” oxides. Photovoltaic and photocatalytic responses are driven by hot electron injection from the “metallic” oxide into the TiO2, enabling new modalities of operation for energy systems.
