  • Window structure for solar cell
    Patent number: 8766087
    Abstract: A multilayer window structure for a solar cell comprises one or more layers where the bottom layer has an intrinsic material lattice spacing that is substantially the same as the emitter in the plane perpendicular to the direction of epitaxial growth. One or more upper layers of the window structure has progressively higher band gaps than the bottom layer and has intrinsic material lattice spacing is substantially different than the emitter intrinsic material lattice spacing.
    Type: Grant
    Filed: May 10, 2011
    Date of Patent: July 1, 2014
    Assignee: Solar Junction Corporation
    Inventors: Rebecca Elizabeth Jones-Albertus, Ferran Suarez-Arias, Michael West Wiemer, Michael J. Sheldon, Homan Yuen
