Abstract
An apparatus and method for solar conversion using nanocoax structures are disclosed herein. A nano-optics apparatus for use as a solar cell comprising a plurality of nano-coaxial structures comprising an internal conductor surrounded by a semiconducting material coated with an outer conductor; a film having the plurality of nano-coaxial structures; and a protruding portion of the an internal conductor extending beyond a surface of the film. A method of fabricating a solar cell comprising: coating a substrate with a catalytic material; growing a plurality of carbon nanotubes as internal cores of nanocoax units on the substrate; oxidizing the substrate; coating with a semiconducting film; and filling with a metallic medium that wets the semiconducting film of the nanocoax units.
