1. A photovoltaic device comprising:

  • a crystalline semiconductor substrate;

    a substantially intrinsic amorphous semiconductor thin-film layer containing hydrogen and provided on the crystalline semiconductor substrate;

    a doped amorphous semiconductor thin-film layer containing hydrogen and provided on the intrinsic amorphous semiconductor thin-film layer; and

    a hydrogen-diffusion reducing area provided between the doped amorphous semiconductor thin-film layer and the intrinsic amorphous semiconductor thin-film layer and reducing hydrogen diffusion from the intrinsic amorphous semiconductor thin-film layer to the doped amorphous semiconductor thin-film layer.
