ABSTRACT:
A photovoltaic element of the present invention is a photovoltaic element having a plurality of pin junctions each formed of a p-type semiconductor layer, an i-type semiconductor layer, and an n-type semiconductor layer each comprising a non-single-crystal material comprising a Group IVA element as a principal component, the photovoltaic element having a first pin junction comprising microcrystal silicon carbide (hereinafter referred to as microcrystal SiC) as a principal component of the i-type semiconductor layer and a second pin junction comprising microcrystal silicon (hereinafter referred to as microcrystal Si) as a principal component of the i-type semiconductor layer, wherein the first pin junction is provided closer to the light incidence side than the second pin junction. Provided thereby are a low cost photovoltaic element which exhibits little photodeterioration and with a high photoelectric conversion efficiency, and production method of the photovoltaic element capable of forming i-type microcrystal silicon and microcrystal SiC at a practical deposition rate.
