<p>A photovoltaic device in which, by optimizing the structures for a substrate-side transparent electrode layer, an intermediate layer, and a back electrode layer, the extracted electrical current can be increased. The photovoltaic device (100) includes at least a transparent electrode layer (2), a photovoltaic layer (3) and a back electrode layer (4) provided on a substrate (1), wherein the surface of the transparent electrode layer (2) on which the photovoltaic layer (3) is disposed includes a textured structure composed of ridges (2a) and a fine micro-texture (2b) provided on the surface of the ridges (2a), the pitch of the textured structure is not less than 1.2 µm and not more than 1.6 µm, the height of the ridges (2a) is not less than 0.2 µm and not more than 0.8 µm, the pitch between peaks in the fine micro-texture (2b) is not less than 0.05 µm and not more than 0.14 µm, and the height of peaks is not less than 0.02 µm and not more than 0.1 µm.</p> |
