    摘要: A silicon based film is provided which comprises a crystal phase formed on a substrate with a surface shape represented by a function f, wherein the silicon-based film is formed on a substrate with a surface shape having a standard deviation of an inclination arctan (df/dx) from 15° to 55° within the range of a sampling length dx from 20 nm to 100 nm. Raman scattering strength resulting from an amorphous component in the silicon-based film is not more than a Raman scattering strength resulting from a crystalline component. A difference between a spacing in a direction parallel to a principal surface of the substrate and a spacing of a single crystal silicon is within the range of 0.2% to 1.0% with regard to the spacing of the single crystal silicon.

    摘要: An object of the present invention is to provide a photovoltaic device and a method of producing the photovoltaic device which can prevent recombination of photo-excited carriers and which permits increases in the open circuit voltage and the carrier range. The photovoltaic device of the present invention has a laminate structure composed of at least a p-type layer of a silicon non-single crystal semiconductor, a photoactive layer having a plurality of i-type layers, and an n-type layer. The photoactive layer has a laminate structure composed of a first i-type layer deposited on the side of the n-type layer by a microwave plasma CVD process, and a second i-type layer deposited on the side of said the p-type layer by an RF plasma CVD process. The first i-type layer deposited by the microwave plasma CVD process contains at least silicon and carbon atoms, and has a minimum band gap between the center thereof and the p-type layer, and the second i-type layer deposited by the RF plasma CVD process contains at least silicon atoms and has a thickness of 30 nm or less.
