    摘要: An improved p-type semiconductor alloy film, an improved substantially intrinsic amorphous semiconductor alloy film, improved photovoltaic and photoresponsive devices incorporating such films and r.f. and microwave glow discharge methods for fabricating same. The improved semiconductor alloy films preferably include at least silicon deposited by the glow discharge of a compound containing at least silicon and a boron species that remains substantially monoatomic as it is incorporated into the silicon matrix. The p-type film is particularly stable, is characterized by a non-narrowed band gap, reduced bulk stress, improved morphology, growth and adhesion and reduced peeling and cracking. The substantially intrinsic film is characterized by substantially reduced Staebler-Wronski degradation. The method includes the novel step of introducing a boron species that does not form higher order boron hydrides or other boron polymers or oligomers in the glow discharge plasma.

    摘要: An optically enhanced back reflector for a photovoltaic device includes a back reflector layer of aluminum having a multi-layered, reflectivity enhancement member deposed thereon. The multi-layer enhancement member includes at least one pair of first and second layers, the first layer having a low index of refraction and the second layer having a high index of refraction. A layer of transmissive conductive oxide is disposed between the optically enhanced back reflector and the photovoltaic device.

    摘要: The disclosure is directed to photovoltaic devices having enhanced short circuit currents and efficiencies. The devices are made by depositing on a previously deposited doped amorphous semiconductor alloy layer a body of intrinsic amorphous semiconductor alloys including a first intrinsic layer, adjacent the doped layer, formed from the deposition of a non-etching starting material and a second intrinsic layer different in composition from the first intrinsic layer. The second intrinsic layer preferably includes silicon and fluorine while the first intrinsic amorphous alloy layer does not include fluorine. The first intrinsic layer may be formed by the glow discharge decomposition of silane gas alone. The thicknesses of the first and second intrinsic layers are adjusted so as to match the respective potential drops thereof with the first intrinsic layer being relatively thin as compared to the second intrinsic layer.
