Abstract: A photoelectrode includes a double-layer homojunction of metal oxide semiconductor films without heteroatoms incorporated. The metal oxide semiconductor films are uniform in large size with rich oxygen vacancies. For BiVO4 films, Bi precursor can be electrodeposited on a substrate under atmospheric pressure and air atmosphere. The electrolytes for electrodeposition are acidic or alkaline with controllable pHs. The electrodeposited substrate is transferred to the muffle furnace for thermal evaporation with V precursor. Film thickness and size can be controlled by electrodeposition parameters. The BiVO4 double-layer homojunction is a safer and cheaper material in photo-driven devices, hydrogen producers, and solar cells, and is an economical replacement of costly III-V compounds, polymers, and valuable fossil.
