| Abstract | We report a new fabrication method of flat, uniform BiVO4 films on an electrically conductive transparent indium tin oxide (ITO) film based on a solution process for depositing bismuth precursor films and a hightemperature calcination process with an organic vanadium precursor. The synthesised BiVO4 films, composed as a monolayer of crystallites (diameter # 1 mm) fixed on the ITO, realised half-cell solar-tohydrogen energy conversion efficiencies of over 1.5% by the aid of impregnated CoOx and atomic-layerdeposited NiO when tested as oxygen-evolving photoanodes for water splitting under solar simulator AM 1.5G illumination. Stoichiometric oxygen and hydrogen were generated with Faraday efficiencies of unity over 12 h at 0.6–0.9 VRHE. This morphology of our bulky semi-transparent BiVO4 films exhibited state-of-the-art solar water splitting performances. |
