For high performance photoanodes such as Si, GaAs, and GaP, amorphous TiO<sub>2<\/sub> protective overlayers, deposited by atomic layer deposition, are conductive for holes via a defect band in the TiO<sub>2<\/sub>. However, when coated on simply prepared, low-cost photoanodes such as metal oxides, no charge transfer is observed through amorphous TiO<sub>2<\/sub>. Here, we report a hybrid polyethyleneimine\/TiO<sub>2<\/sub> layer that facilitates hole transfer from model oxides BiVO<sub>4<\/sub> and Fe<sub>2<\/sub>O<sub>3<\/sub>, enabling access to a broader scope of available materials for practical water oxidation. A thin polyethyleneimine layer between the light absorber and the hybrid polyethyleneimine\/TiO<sub>2<\/sub> acts as a hole-selective interface, improving the optoelectronic properties of the photoanode devices. These polyethyleneimine\/TiO<sub>2<\/sub> modified photoanodes exhibit high photostability for solar water oxidation over 400 h.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1038\/s41467-024-53754-9 Authors: Sanghyun Bae, Thomas Moehl, Erin Service, M.
