  • Thin-film solar cells and method of making
    Patent number: 7041342
    Abstract: There are now provided thin-film solar cells and method of making. The devices comprise a low-cost, low thermal stability substrate with a semiconductor body deposited thereon by a deposition gas. The deposited body is treated with a conversion gas to provide a microcrystalline silicon body. The deposition gas and the conversion gas are subjected to a pulsed electromagnetic radiation to effectuate deposition and conversion.
    Type: Grant
    Filed: October 10, 2003
    Date of Patent: May 9, 2006
    Assignee: Schott Glas
    Inventors: Manfred Lohmeyer, Stefan Bauer, Burkhard Danielzik, Wolfgang Möhl, Nina Freitag
