Abstract
A photovoltaic device according to the present disclosure includes: a first-conductivity-type semiconductor film provided on a back side of a semiconductor substrate; a second-conductivity-type semiconductor film in which at least a part thereof is provided in a position different, in plan view, from a position of the first-conductivity-type semiconductor film on the back side of the semiconductor substrate; a protective film, which is formed on a back side of the first-conductivity-type semiconductor film and a back side of the second-conductivity-type semiconductor film, and which includes a conductive portion and a non-conductive transformed portion; and an electrode film formed on a back side of the conductive portion. The transformed portion of the protective film is provided along a conduction path between a back surface of the first-conductivity-type semiconductor film and a back surface of the second-conductivity-type semiconductor film.
