PURPOSE:To simplify a constitution, to make an effective area large and to improve manufacturing efficiency, by connecting a plurality of photovoltaic elements, which form a continuous annular shape without cut parts, in series on a substrate. CONSTITUTION:A light-transmitting insulating substrate 1 is formed in a disk shape. On the main surface of the substrate, a transparent electrode 2, an amorphous semiconductor layer 3 and a back surface electrode 4 are formed and laminated in this order. Photovoltaic elements A and B in an continuous annular shape without cut parts are arranged at the inside and outside in a concentric pattern. The inner and outer photovoltaic elements A and B are connected in series. |
