Abstract:
A process for producing a photovoltaic element having at least one pin junction above a substrate, and a buffering semiconductor layer constituted of plural sublayers between at least an n-type layer and an i-type layer 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, wherein, in electric discharge generation for formation of at least one of the buffering semiconductor layer, 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.
