ABSTRACT:
A changeable optical energy charging type half cell which essentially comprises a metal electrode with a lead wire, and a thin plate of photoactive-semiconductor in contact with the metal electrode. The metal electrode and thin plate are immersed in an electrolyte containing metal ions from which metal is deposited. The thus constituted half cell is used to form a photochemical battery incorporating an oxidation-reduction system half-cell. The two half-cells are connected to each other through a material which does not interrupt the movement of ions therebetween.
