Abstract
Abstract Photoelectrogenerative cell means comprising, in combination, cell means including an anolyte cell and a catholyte cell, with means being provided for the transmission of solar radiation into the anolyte cell. The anolyte cell includes an electroconductor solution, along with a photoelectrogenerative compound in admixture therewith, the photoelectrogenerative material being dispersed or dissolved in the electroconductive solution. The catholyte cell comprises an electroconductor in solution, and an electrolytically permeable cell isolation means separates the anolyte cell from the catholyte cell. Electrically conductive electrodes are immersed in each of the respective anode compartments and cathode compartments, and are arranged in electrical contact with the respective anolytes and catholytes. This photoelectrogenerative cell recovers energy produced by photoelectrochemical reactions when placed in a cell configuration.
