<p>PROBLEM TO BE SOLVED: To prevent Na from a translucent insulating board from entering a photovoltaic element and deteriorating characteristics since the amount of oxygen is large, and to reduce absorption at a long wavelength. SOLUTION: The photovoltaic module 30 has a plurality of photovoltaic elements 31 having the lamination structure of a transparent conductive film 6, an amorphous or a microcrystalline conductive type semiconductor layer 4, and a crystal-based semiconductor substrate 1 from the surface of a light reception surface side at least at the light reception surface side of nearly a plate-like photovoltaic module 31. In the transparent conductive film 6 of the photovoltaic element 31, carrier density is set to less than 6×10<20> /cm<3> . The amount of oxygen is large, thus preventing Na from a translucent insulating board from entering the photovoltaic element and deteriorating characteristics, and reducing the absorption at the long wavelength.</p> |
