PURPOSE:To ensure quick connection without causing troubles such as short circuits, by coating an element part, to which conductivity is not desired to be applied, by an insulating body, applying a conductive paste thereon, and connecting photovoltaic elements. CONSTITUTION:A CdS thin film 2 is formed on a glass substrate 1 by a screen printing method and heat treatment. A CdTe thin film 3 is formed thereon by the same way. A carbon thin film 4 including a minute amount of acceptor impurities is provided thereon. Thus a photovoltaic element is formed. When the element is used as a single body, ohmic electrodes 5 and 6 are attached to said CdS thin film 2 and carbon thin film 4, respectively, and the photovoltaic force can be taken out by lead wires. When plurality of elements are connected and used, the ohmic electrode 5 and the ohmic electrode 6 of the other element must be connected. Therefore, an insulator 9 is coated on the ohmic electrode 6. Then, a conductive paste 7 is applied so as to coat both the ohmic electrode 6 on the left side element and the ohmic electrode 5 of the right side element. |
