NOVELTY - A hybrid photovoltaic device (300) comprises a conducing layer on a top surface of substrate (301), which forms an electrode; a nanostructure supporting layer (303) on the conducting layer where nanostructures (310) are arranged in a two dimensional array and project vertically upwards from the surface of the layer; a matrix comprising two nanostructure-surrounding layers (304, 305) to surround and embed the nanostructures; and another conducting layer that forms another electrode having an opposite polarity from that of the first electrode.    USE - Hybrid photovoltaic device useful for photovoltaic power generation.    ADVANTAGE - The hybrid photovoltaic device is cost effective because it integrates nanostructure technology with photovoltaic device technology for high efficiency. It is a clean energy source and is an alternative to fossil fuels and nuclear energy.    DETAILED DESCRIPTION - A hybrid photovoltaic device (300) comprises substrate (301) with bottom and top surfaces; a conducing layer on the top surface of substrate, which forms an electrode; a nanostructure supporting layer (303) on the conducting layer where nanostructures (310) are arranged in a two dimensional array and project vertically upwards from the surface of the layer; a matrix comprising nanostructure-surrounding layer (304) on nanostructure supporting layer that fills space between nanostuctures and partially embedding the nanostructures, and another nanostructure-surrounding layer (305) that fills remaining space between nanostructures and fully embedding the nanostructures in the matrix; and another conducting layer that forms another electrode having an opposite polarity from that of the first electrode. In response to an incident photon flux, photo-carriers is generated in the hybrid photovoltaic device. Each photo-carrier has an electric charge, positive or negative, but not both, and upon being collected according to their charge, by the electrodes, the photo-carriers generate an electric current. The nanostructures comprise nanocylinders, nanopillars, or nanowires. They are constructed from a material different from the supporting and surrounding layers. Each nanostructure has a nominal height and a nominal footprint diameter. The nominal height is substantially larger than the nominal footprint diameter, such that the total surface area of the nanostructures is substantially larger than the total footprint area. An INDEPENDENT CLAIM is included for a method of generating electric current in a hybrid photovoltaic device.
