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.

A film, typically a silicon-based film, is formed on a substrate by means of a plasma CVD process using a high frequency wave in a condition where a resistance element made of a different material than that of the substrate is provided on the electric path between the substrate and the earth.

A method for manufacturing a photoelectric conversion device including a forming a semiconductor film by a plasma CVD method. The semiconductor film is an amorphous film of SiGe-based compound or a microcrystalline film of SiGe-based compound. The plasma CVD controls bandgap in thickness direction of the semiconductor film by varying the ON or OFF time of electric power applied to generate a plasma and intermittently supplying the power. The ON time and OFF time of the power fall in a range where the duty ratio ON time/(ON time+OFF time)×100(%) is 10% or more and 50% or less.

In a zinc oxide film having a plurality of texture constituents comprised of hills each having structure wherein a first surface borders on a second surface along one curved line, texture constituents in which first surfaces the hills of the texture constituents have have an average angle of inclination in a size within the range of from 30 degrees or more to 60 degrees or less and second surfaces have an average angle of inclination in a size within the range of from 10 degrees or more to 35 degrees or less account for at least a half of the plurality of texture constituents. This enables improvement in characteristics and durability of zinc oxide films used as optical confinement layers in photovoltaic devices, and also enables formation thereof at a low cost.
