Integrated device and substrate for separating charged carriers and reducing photocorrosion and method for the photoelectrochemical production of electricity and photocatalytic production of hydrogen
The invention provides a system for separating oppositely-charged charge carriers, the substrate comprising a semiconductor; a ligand in electrical communication with said semiconductor; an ion-exchange resin attached to the semiconductor; an ion-exchange membrane; and an electrical conduit attaching said resin to said membrane. Also provided is a method for producing hydrogen gas, comprising: inducing charge separation in semiconductor particles so as to produce electrons and holes; oxidizing water with the holes to produce oxygen ions and protons, wherein the protons are sequestered from the oxygen ions as the protons are produced; and directing the sequestered protons to a cathode. The invention also provides a method to produce electricity comprising, inducing charge separation in semiconductor particles so as to produce electrons and holes, and completing the circuit with an electron hole transporter.
