NOVELTY - The device has an electrode (203a) electrically connected to a layer of an electrical conductive material. Another electrode (203b) is electrically connected to a substrate (200) such that vertical rods (201) of a two-dimensional array are connected to the latter electrode comprising opposite polarity relative to the layer. The layer forms charge separating junctions at interfaces with the rods of the array and the substrate. A common carrier panel comprises a top surface and a bottom surface. Photovoltaic cells are connected to the top and bottom surfaces of the panel, respectively.    USE - Photovoltaic device i.e. solar device, for generating electric power used in an enormous application. Uses include but are not limited to space application, commercial application, residential application and industrial application.    ADVANTAGE - The device provides high power generation capability per unit area. The device reduces recombination of carriers such that the absorption of light can be increased, thus effectively increasing the photogenerated carriers. The rods are made of electronic materials such as silicon, germanium, and glass such that cost of the rods material can be decreased. The device captures most of wavelengths belonging to a solar spectrum such that more than 80% of conversion efficiency can be provided. The device generates electric power when the sun is available or not.    DETAILED DESCRIPTION - The common carrier panel is made of dielectric material, insulator material, and polymer material. The photovoltaic cells are made of materials suitable for absorbing radiation from visible spectrum and infrared radiation. The substrate is made of polymer and ceramic.
