1. A nanostructured material system for efficient collection of photo-excited carriers, comprising:
(a) a plurality of nanostructured elements, each nanostructured element including:
(i) a plasmonic transparent conductive oxide core material element coupled with a corresponding semiconductor material element, and
(ii) a plurality of catalytic metal nanoparticles separately deposited on a surface of each semiconductor material element; and
(b) a substrate upon which each of the plurality of nanostructured elements is mounted;
wherein the nanostructured elements are each configured to form ohmic junctions at the surface of the semiconductor material elements or in close proximity with the semiconductor material elements, wherein the nanostructured elements are operable to absorb broadband light to enhance hot carrier generation.
