ABSTRACT:
Surface recombination in solar cells that is produced by band bending at the surface of the semiconductor which is in turn caused by defect states which pin the Fermi level at the surface, may be improved by applying a surface layer which may be a plasma oxide that has been hydrogen annealed and this layer may also be useful as an antireflecting coating.
