Abstract: A photoactive article includes a substrate including a semiconductor to absorb light and to produce a plurality of charge carriers; a dielectric layer disposed on the substrate; a conductive member disposed on the dielectric layer and opposing the substrate such that the dielectric layer is exposed by the conductive member, the conductive member to receive a portion of the plurality of charge carriers from the substrate; and an electrolyte disposed on the dielectric layer and the conductive member. Making a photoactive article includes forming a dielectric layer on a substrate by rapid thermal oxidation, the dielectric layer comprising an oxide of a semiconductor; and forming a conductive member disposed on the dielectric layer.
