  • Fabrication of photovoltaic devices by solid phase epitaxy
    Patent number: 4165558
    Abstract: Fabrication of photovoltaic devices by solid phase epitaxy; devices produced by this method consisting of a semiconductor base and a semiconductor junction-forming epitaxial layer. The epitaxial layer grown by solid phase means from a metal-semiconductor alloy or from a sandwich structure of semiconductor/metal on the semiconductor base.
