    摘要: A deposition apparatus of the present invention is arranged so that a surface area of a radio-frequency power applying cathode electrode disposed in a glow discharge space, in a space in contact with discharge is greater than a surface area of the whole of a ground electrode (anode electrode) including a beltlike member in the discharge space. This structure can maintain the potential (self-bias) of the cathode electrode disposed in the glow discharge space automatically at a positive potential with respect to the ground (anode) electrode including the beltlike member. As a result, the bias is applied in the direction of irradiation of ions with positive charge to a deposit film on the beltlike member, so that the ions existing in the plasma discharge are accelerated more efficiently toward the beltlike member, thereby effectively giving energy to the surface of deposit film by ion bombardment. Accordingly, since the structural relaxation of film is promoted even at relatively high deposition rates, a microcrystal semiconductor film can be formed at the relatively high deposition rates with good efficiency, with high uniformity, and with good reproducibility.

    摘要: A photovoltaic device comprises a semiconductor region having at least one set of semiconductor layers comprised of a first semiconductor layer having a first conductivity type, an intrinsic or substantially intrinsic second semiconductor layer, and a third semiconductor layer having a conductivity type opposite to that of the first conductivity type, the layers being formed in this order, and first and second electrodes provided such that the electrodes interpose the semiconductor region; wherein the density of a dopant impurity determining the conductivity type of the first semiconductor layer in a set of semiconductor layers which is in contact with the first electrode is varied so as to be lower on the side of the first electrode, or the grain size of crystals in the first semiconductor layer is varied so as to be smaller on the side of the first electrode. This provides a photovoltaic device that does not exhibit great lowering of characteristics even when short circuits locally occur in the semiconductor layers during long-term service.
