摘要:
A process is provided for producing a photovoltaic element which has at least one pin junction, and a buffering semiconductor layer constituted of plural sublayers between an n-type layer and an i-type layer and/or between an i-type layer and a p-type layer, through production steps of introducing a source material gas into an electric discharge space in a reaction chamber, and decomposing the source material gas by plasma discharge to form a non-monocrystalline semiconductor layer. In the process, in electric discharge generation for formation of at least one of the sublayers, the polarity of the electrode confronting the substrate for formation of a first sublayer and the polarity of the electrode confronting the substrate for formation of a second sublayer adjacent to the first sublayer is made different from each other, or the potential of one of the electrodes is set at zero volt. Thereby, diffusion of the dopant from the p-type layer or the n-type layer into the i-type layer is prevented effectively. The produced photovoltaic element is improved in the output properties, the open-circuit voltage, and the fill factor, and these properties deteriorate less.

摘要:
An apparatus for forming a non-single-crystal semiconductor thin film comprising a film deposition chamber having a film-forming space surrounded by a film deposition chamber wall and a beltlike substrate, and an external chamber surrounding the deposition chamber wall is provided. While the beltlike substrate is moved in a longitudinal direction, a film-forming gas is introduced through a gas supply device into the film-forming space and microwave energy is radiated from a microwave applicator into the film-forming space to induce a microwave plasma, and thereby form a non-single-crystal semiconductor thin film on a surface of the beltlike substrate. A cooling mechanism and a temperature-increasing mechanism are provided to cover a part of an outside surface of the deposition chamber wall. An apparatus for forming a non-single-crystal semiconductor thin film where the gas supply device comprises a gas manifold set apart from the deposition chamber wall is another embodiment.
