Abstract

Abstract : Photoelectrochemical water splitting is far more efficient thanks to the novel ZnOSe/ZnO/BZO thin‐film photoanodes fabricated in this work. A novel structure is developed for simultaneously suppressing the charge recombination in the ZnO bulk and at the semiconductor–electrolyte interface. This structure achieves a five‐fold enhancement in water‐splitting performance, compared to that of pristine ZnO photoanodes, when illuminated using visible light.
