Abstract
A number of aligned and spaced photogalvanic cells/compartments have interior passages formed therebetween to permit the free passage of electrolyte. Each compartment includes spaced electrodes and a TiO.sub.2 -electrolyte photoactive site. A layer of charge storing material, such as tungsten oxide may be incorporated in each compartment. As a result, each compartment is capable of converting light energy to electrical energy and also storing charge within the cell after light irradiation ceases. By connecting the various electrodes of the compartments in parallel, greater current flow may be appreciated.
