Abstract
A photovoltaic device includes a monocrystalline or polycrystalline semiconductor layer of one conductivity type, a substantially intrinsic substantially amorphous semiconductor layer having a predetermined thickness small enough to avoid producing carriers therein. The substantially intrinsic, substantially amorphous layer is formed on the one conductivity type semiconductor layer, and a substantially amorphous semiconductor layer of the opposite conductivity type is formed on the intrinsic, semiconductor layer.
