Abstract
A photovoltaic device includes: a p- or n-type semiconductor substrate; a p-type amorphous semiconductor film and an n-type amorphous semiconductor film on a first-face side; p-electrodes on the p-type amorphous semiconductor film; and n-electrodes on the n-type amorphous semiconductor film, wherein: the p-electrodes and the n-electrodes are arranged at intervals; the p-type amorphous semiconductor film surrounds the n-type amorphous semiconductor film in an in-plane direction of the semiconductor substrate; the n-type amorphous semiconductor film has an edge portion providing an overlapping region where the n-type amorphous semiconductor film overlaps the p-type amorphous semiconductor film; and the n-electrodes are disposed in areas of the n-type amorphous semiconductor film that are surrounded by the overlapping region.
