Solid state photoelectrochemical cell
Patent
·
OSTI ID:6638571
A solid state photoelectrochemical cell is described providing in-situ electrochemical energy storage having a homogeneous solid electrolyte matrix and associated ionic conductors with a central electrolyte separator portion providing ionic conductance and an oxidant portion on one side and a reductant portion on the other side each having redox couples in fixed lattice positions and possessing ionic and electronic conductivity. At least one photosensitive photoelectrode is in ionic communication with the oxidant and/or reductant portion(S) whereby electrons or electron holes are transmitted to that portion while the photoelectrode is illuminated causing oxidation or reduction of the redox couple. The apparatus and process provide conversion of solar to electrical energy using a solid state photoelectrochemical cell.
