Abstract
A surface-plasmon enhanced photovoltaic device including: a first metallic electrode having an array of apertures, an illuminated surface and an unilluminated surface, at least one of the surfaces having an enhancement characteristic resulting in a resonant interaction of incident light with surface plasmons; a second electrode spaced from the first metallic electrode; and a plurality of spheres corresponding to the array of apertures and disposed between the first metallic and second electrodes, each sphere having a first portion of either p or n-doped material and a second portion having the other of the p or n-doped material such that a p-n junction is formed at a junction between the first and second portions.
