Patents by Inventor Wolfgang Kruhler

Wolfgang Kruhler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20060102976
    Abstract: A photovoltaic component with a silicon wafer that has a basic doping, a light-receiving side, and an electric bonding side opposite the light-receiving side. At least one interdigital semiconductor structure is arranged on the electric bonding side. The interdigital semiconductor structure has at least one n-type semiconductor part-structure and at least one p-type semiconductor part-structure arranged at a certain interval to the n-type semiconductor part-structure. One of the semiconductor part-structures and the silicon wafer form a p-n junction.
    Type: Application

  • Patent number: 7029943
    Abstract: A photovoltaic component with at least one silicon wafer that has a certain basic doping, a light-receiving side, and electric bonding side opposite the light-receiving side, and at least one interdigital semiconductor structure arranged on the electric bonding side with at least one n-type semiconductor part-structure and at least one p-type semiconductor part-structure arranged at a certain interval to the n-type semiconductor part-structure. One of the semiconductor part-structures and the silicon wafer thus forms a p-n junction. The silicon wafer may be a tri-crystalline wafer.

  • Publication number: 20040043528
    Abstract: A photovoltaic component with at least one tricrystalline wafer (2) that has a certain basic doping, a light-receiving side (3), an electric bonding side (4) opposite the light-receiving side (3), and at least one interdigital semiconductor structure (5) arranged on the electric bonding site (4) with at least on n-type semiconductor part-structure (6) and at least one p-type semiconductor part-structure (7) arranged at a certain interval (8) to the n-type semiconductor part-structure (6). One of the semiconductor part-structure and the silicon wafer (2) thus form a p-n junction (9).

  • Patent number: 4001704
    Abstract: A highly doped optical amplifier in the form of a thin layer or fiber wherein the pump light is directed transversely to the surface of the layer or fiber. A transparent substrate is provided underneath the layer or fiber and a solar cell is provided in light receiving relationship to light passing through the layer or fiber on the opposite side of the substrate.
