  • Patent number: 10763003
    Abstract: A method of manufacturing a charge dissipative surface layer on a member made from or consisting of a dielectric polymeric material or polymer-based composite which is intended to be used in space and other extreme environments, the member having at least one surface, in particular two opposing surfaces, each of the surfaces having a flat or a three-dimensional shape. The method includes carbonizing the at least one surface of the member in a vacuum environment through ion bombardment with simultaneous surface renewal in a dynamic way, by bombardment of the at least one surface with an ion beam formed in a gaseous linear high-current technological ion beam source of rare gas and added predetermined amount of a carbonaceous gas in the same ion beam gas admixture in order to achieve a treated carbonized surface layer with a uniform surface resistivity in a charge-dissipative range.

    Abstract: A hinge assembly comprises first and second tape spring elements, wherein each of the spring elements is configured to connect a first element of a space structure to a second element of the space structure. Each of the first and the second tape spring elements is movable from a folded state into an unfolded state by releasing stored strain energy, to deploy the first and the second element of the space structure. The first tape spring element is connected to a first direct current source and configured to conduct direct current of a first polarity supplied to the first tape spring element from the first direct current source. The second tape spring element is connected to a second direct current source and configured to conduct direct current of a second polarity, opposite to the first polarity, supplied to the second tape spring element from the second direct current source.

  • Patent number: 8355561
    Abstract: A method for screening of multi-junction solar cells to be operated in a high sun intensity and high temperature (HIHT) environment. An electroluminescence image of a homogeneous pn-junction at a predefined bias current is acquired for each of the solar cells. The spatial intensity distribution in the electroluminescence image is analyzed to determine whether there are local intensity variations that possibly dissipate power in a HIHT environment. The solar cells are sorted such that solar cells having no local intensity variations in their electroluminescence image are put into a first group and solar cells having at least one local intensity variation in their electroluminescence image are put into a second group cells for further screening. The solar cells of the first group are suitable for a HIHT environment and solar cells of the second group are assumed to be potentially critical in a HIHT environment.

  • Patent number: 8306309
    Abstract: A process detects defects in a semiconductor device, particularly a solar cell or solar cell arrangement, having at least one pn junction in a semiconductor layer of a semiconductor material with an indirect band junction. A voltage is applied to the at least one pn junction to operate it in the transmitting direction; and the radiation behavior of the semiconductor layer generated by the applied voltage, at least for partial ranges of the semiconductor layer, is optically detected and automatically examined for essentially one-dimensional intensity changes in order to detect mechanical defects.
