NOVELTY - The PV power module includes several rear contact PV cells mounted on a single conductive receiver board, in which the first and second conductive surfaces of each rear contact PV cell are respectively and electrically connected to the first and second conductive paths of the conductive receiver board. A primary lens sheet (48), comprising of lenses corresponding to the rear contact PV cells, is provided for concentrating the light rays. Each lens of the primary lens sheet focuses the light rays across the photoactive surface of each rear contact PV cell.    USE - PV power module for use in space applications.    ADVANTAGE - Uses small lenses concentrating onto small high-efficiency rear contact solar cells, in which small lenses formed into a sheet, concentrating onto small PV cells dispersed over the entire module area, shortens the required focal length. Ensures that heat dissipation from several small PV cell sites is efficient and economically attained. Ensures that the lens efficiency is very high since there are no Fresnel facets to obscure light transmission. Ensures that the lenses are relatively small allowing for a high efficiency lens that is thin, which minimizes the lens material. Ensures that the integration of lens design with rear contact PV cells, as opposed to front and back contact PV cells, allows for higher concentration, higher efficiency and simple, automated assembly techniques. Ensures that the rear contact PV cells may be soldered to a standard surface mount printed circuit board or similar substrate or receiver sheet using well-known robotic assembly and soldering methods. Ensures that the PV cells, in combination with the receiver sheet, may be encapsulated for environmental protection. Ensures that the receiver sheet assembly may also be encapsulated with a small secondary lens over each PV cell to further enhance the acceptance angle, relaxing the tracking accuracy requirements. Includes a secondary lens that improves the light distribution received by the PV cell from the primary optical element. Includes point focus optics and small PV cells dispersed onto a large receiver sheet, allowing the heat to be effectively dissipated without the use of auxiliary cooling devices.    DETAILED DESCRIPTION - The first conductive path is electrically isolated from the second conductive path of the conductive receiver board. A secondary lens sheet (72) is disposed between the primary lens sheet and photoactive surface of each rear contact PV cell for uniformly distributing the light rays on each PV cell. An INDEPENDENT CLAIM is also included for the PV power module manufacture method.
