Claim Text:
1. A field-enhancing energy collection device, comprising: a substrate comprising a base surface, the base surface comprising a recessed structure having one or more angled wall surfaces that taper downward away from the base surface, between which one or more angled wall surfaces is formed a recess void, the recess void being empty or filled with a transparent or translucent material, the one or more angled wall surfaces coming in contact or close proximity to one another at a distance from the base surface, the one or more angled surfaces comprising an electromagnetic energy conducting waveguide optically exposed to the recess void, wherein the electromagnetic energy conducting waveguide is formed of a metallic material; and an electrode adjacent or in close proximity to the substrate, thereby forming a gap between the electrode and the electromagnetic energy conducting waveguide, wherein the gap comprises a photovoltaic material, and wherein the field-enhancing energy collection device comprises a field enhancement region separated from the electrode.
