Abstract
A photogalvanic cell has a glass substrate through which irradiating light passes. A light transparent conductive thin film serves as an electrode, the film being deposited upon the glass substrate. Another layer is an electrolyte and includes an aqueous medium having TiO.sub.2 suspended therein, the TiO.sub.2 forming photoactive sites with the remaining ingredients of the electrolyte. The electrolyte layer further includes N-methylphenazine methosulfate dye which has photoconversion and electrical storage properties. During irradiation the cell may drive a load, or stored energy resulting from irradiation may drive a load after the source of irradiation is removed.
