Patent ID: 7981261

Claim:
A system for separating oppositely-charged charge carriers, the system comprising: a) an electrically conductive support; b) a semiconductor attached to the support, the semiconductor adapted to receive radiation so as to generate electrons and holes; c) a ligand covalently attached to said semiconductor to form a construct; whereas the holes are localized on the ligand; d) an electric conduit attached to said ligand so as to physically isolate the construct from adjacent structures or fluids; e) a porous resin wafer fabricated from ion exchange resins in electrical communication with the electric conduit; f) an electron hole transport membrane such that said resin wafer is positioned intermediate the construct and said membrane; g) a cathodic compartment containing electrolyte, such that said membrane is positioned between the cathodic compartment and resin wafer; and h) an electrical connection between said cathodic compartment and the conductive support.
