The purpose of the present invention is to provide a photovoltaic device that has a high fill factor. This photovoltaic device (10) is provided with a multilayer photovoltaic element (11), a first collection member (12) laminated to one surface of said photovoltaic element (11), and a second collection member (13) laminated to the other surface of the photovoltaic element (11). The photovoltaic element (11) has the following: an n-type crystalline semiconductor substrate (14); a first intrinsic amorphous silicon thin film (15), a p-type amorphous silicon thin film (16), and a first transparent conductive film (17) layered in that order on the side of the n-type crystalline semiconductor substrate (14) facing the first collector member (12); and an n-type amorphous silicon thin film (19) and a second transparent conductive film (20) layered in that order on the side of the n-type crystalline semiconductor substrate (14) facing the second collector member (13). The p-type amorphous silicon thin film (16) is less than 6 nm thick, and the maximum width (S1) of the regions (25) of the surface of the first transparent conductive film (17) not covered by the first collector member (12) is less than 2 mm. |
