  • System and Method for High Yield Deposition of Conductive Materials onto Solar Cells
    Publication number: 20110277823
    Abstract: A system for reducing damage to solar cells during a process for depositing a conductive material on a solar cell is disclosed where an electrical bias or floating potential is applied to the solar cell; and/or an electrical bias is applied to an external electrode(s) so that charged particles of a certain type are redirected away from the solar cells, avoiding the creation of a sufficiently high reverse bias on the solar cell to breakdown the cell.
    Type: Application
    Filed: May 19, 2009

    Applicants: MWOE SOLAR, INC., UNIVERSITY OF TOLEDO
    Inventors: Qi Hua Fan, Michael Deng, Xianbo Liao, Xunming Deng
  • Hybrid window layer for photovoltaic cells
    Patent number: 8030120
    Abstract: A novel photovoltaic solar cell and method of making the same are disclosed. The solar cell includes: at least one absorber layer which could either be a lightly doped layer or an undoped layer, and at least a doped window-layers which comprise at least two sub-window-layers. The first sub-window-layer, which is next to the absorber-layer, is deposited to form desirable junction with the absorber-layer. The second sub-window-layer, which is next to the first sub-window-layer, but not in direct contact with the absorber-layer, is deposited in order to have transmission higher than the first-sub-window-layer.
    Type: Grant

    Date of Patent: October 4, 2011
    Assignee: The University of Toledo
    Inventors: Xunming Deng, Xianbo Liao, Wenhui Du
