  • Photovoltaic cells for converting light energy to electric energy and photoelectric battery
    Patent number: 5158618
    Abstract: A solar photovoltaic cell with a conductive current collecting contacts embedded in a block of optical transparent polymer material between the semiconductor wafer and protective cover in such a manner that at least the section thereof which are in contact with the surface of the semiconductor wafer protrude from the polymer block. This provides for a reliable ohmic contact between the current collecting contacts and the semiconductor wafer. The disclosed geometry of the solar cell reduces the shadowing area of the semiconductor wafer by up to 90%.
