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： A method of manufacturing a photoelectric transducer forms a functional film on a conductive substrate. The method comprises applying ultrasonic cleaning with a cleaning liquid containing water to the conductive substrate, then allowing the surface of the conductive substrate to contact purified water so as to import uniform oxidation and then forming the functional film thereon. The functional film is characterized in being formed with a metal layer as light-reflecting layer, a reflection enhancing layer, and a semiconductor photovoltaic device layer, prepared by a plasma CVD method, comprising a non-monocrystalline material containing silicon atoms as the matrix.

摘要： A photovoltaic element has a first conduction type semiconductor layer 103 of the n+-type or the p+-type, an intrinsic semiconductor layer 108 of the i-type, and a second conduction type semiconductor layer 105 of the p+-type or the n+-type successively stacked on a substrate 101. When a unit 107 is defined as a set of a first microcrystal silicon base semiconductor layer 103 and a second microcrystal silicon base semiconductor layer 104 of mutually different absorption coefficients at 800 nm, the i-type layer 108 includes at least two such units. This makes it possible to provide the photovoltaic element that can absorb the light efficiently with avoiding the light degradation phenomenon (Staebler-Wronski effect) specific to amorphous semiconductors and that has good electric characteristics (mobility &mgr;, lifetime &tgr;) and the like.
