Abstract
Official abstract text for this publication.
Photovoltaic devices and techniques for enhancing efficiency thereof are provided. In one aspect, a photovoltaic device is provided. The photovoltaic device comprises a photocell having a photoactive layer and a non-photoactive layer adjacent to the photoactive layer so as to form a heterojunction between the photoactive layer and the non-photoactive layer; and a plurality of high-aspect-ratio nanostructures on one or more surfaces of the photoactive layer. The plurality of high-aspect-ratio nanostructures are configured to act as a scattering media for incident light. The plurality of high-aspect-ratio nanostructures can also be configured to create an optical resonance effect in the incident light.
First claim
