ABSTRACT:
A photochemical energy storage system includes at least one electrolytic solution containing a reduction-oxidation couple, one species of which can be stored in a second phase. The device includes a charging system and an energy delivery system. The charging system includes an n-or p-type photosensitive electrode at which, under illumination, an oxidation or reduction reaction occurs. In the charging cycle, one species is oxidized while the other is reduced, and one of these products is stored in a phase other than the phase in which the reaction occurs. The energy delivery system transfers electrons to or from the high energy product on demand for delivery through an electrical load to an electrode at which the original reactants can be reconstituted.
