Polycrystalline GaAs solar cells on low-cost Silicon-Film super(TM) substrates
Conference record of the IEEE Photovoltaic Specialists Conference

Abstract
We assess the potential of a low-cost, large-area Silicon-Film super(TM) sheet as a substrate for thin-film polycrystalline GaAs solar cells. Silicon-Film super(TM) is a relatively inexpensive material on which large-grain ( > 2 mm) polycrystalline GaAs films can be formed. The GaAs epitaxial layers are grown by a simple close-spaced vapor transport (CSVT) technique using water vapor as a transport agent. A recrystallized Ge sub(1-x)Si sub(x) buffer layer between the GaAs epilayer and Silicon-Film super(TM) substrate can facilitate growth of the GaAs. Selective epitaxy on patterned, oxide-masked substrates is effective in reducing thermal stress effects.
