Triple electrode photogalvanic cell with energy storage capability

摘要

A photogalvanic cell includes a glass substrate with a transparent electrode which receives irradiating light energy. A second electrode is positioned in spaced relationship from the first electrode and has a thin film of charge storing tungsten oxide deposited thereon. Spaced from both the transparent electrode and the tungsten oxide thin film is a counterelectrode. An electrolyte having TiO2 powder mixed therein forms a photoactive site at the surface of the transparent electrode. By physically separating the tungsten oxide thin film from the transparent electrode, more light irradiates the TiO2 thereby increasing the photoconversion of the cell.
