PURPOSE:To improve the reliability of a photovoltaic device by connecting a photovoltaic element using an amorphous silicon film with an amorphous silicon film to become low resistance at the time of emitting a light to form the device, thereby eliminating use of at least one of a metal electrode film and a transparent conductive film. CONSTITUTION:Photovoltaic elements 10 formed by isolating on a glass substrate 1 have a pin structure containing p type layers 11, i type layer 12 and n type layer 13, and generates photovoltaic power with the light incident through a glass plate 1. The layers 11, 13 respective have connectors 14, 15, both of which are made of amorphous silicon film. The elements 10 are bonded by superposing the connectors 14, 15 of the p type and n type layers. Since the p type and n type layers become low resistance upon emitting of the light, i.e., upon generating of photovoltaic power of the elements 10, the photovoltaic powers are connected in series or in parallel with low power loss. |
