ABSTRACT:
Disclosed is a method of fabricating a vertical multi-junction cell and the solar cell produced thereby, utilizing an orientation dependent etch to selectively provide parallel grooves in monocrystalline silicon body, followed by the introduction of doping impurities of the opposite conductivity type from the silicon body to provide PN junctions. In some instances the grooves are filled with silicon of the same conductivity type as the silicon body.
