Description of the Related Art An amorphous semiconductor thin film formed by glow discharge decomposition of a raw material gas or photo CVD is formed at a low temperature, so that it can be easily formed on a flexible substrate such as a polymer material. Therefore, it is expected as a material for a solar cell to be installed on a building material, an automobile sunroof, or any other object having a curved surface. In order to obtain a large electric power with such an amorphous solar cell, it is necessary to electrically connect a plurality of cells. Therefore, conventionally, the solar cells are arranged on the same plane, and the electrode portions at the ends are connected to each other by a conductive tape. FIG. 2 shows a solar cell device using a conductive tape, which is formed on a flexible insulating substrate 1 such as a polymer material having a light-transmitting property with respect to a power generation wavelength range of a solar cell made of SnO 2 or ZnO. A transparent electrode 2 having translucency and conductivity is formed, and an amorphous semiconductor thin film 3 which is a photovoltaic generation part, and then a metal electrode 4 are sequentially laminated on the transparent electrode 2. The solar cells 11 and 12 having such a structure are arranged on the same plane, and adjacent solar cells are sequentially connected in series. In this case, since the flexible insulating substrate 1 has poor solder wettability and a low melting point, connection by soldering is difficult, and the adjacent metal electrodes 41, 42 are electrically connected by the conductive tape 5 having adhesiveness. Connect to each other. However, the electrodes glued with conductive tape
Since the portions 41 and 42 have the same potential, they do not contribute to power generation, and the power generation efficiency per unit area is low.

ことが困難になる。However, when a plurality of solar cells are connected in series by using a conductive adhesive as shown in FIG. 3, the connection strength of the connecting portion is not sufficient, especially at high temperature.
Due to the low reliability of adhesion under high humidity, it is not possible to construct a solar cell device with only a flexible substrate, and the glass substrate 10
Must be held using. Therefore, it is impossible to install on a material having a curved surface while using a flexible substrate. It is desirable to be able to utilize brazing, such as soldering, to make a connection that has high strength and low resistance and can be electrically connected. If a solar cell in which a flexible substrate having a metal electrode on its surface is bent at 180 ° C. and a metal electrode is extended to the back side of the end portion described in the patent publication, the metal electrodes can be soldered together. Although it is possible to connect a flexible substrate, since the thickness of the connecting portion is 3 to 4 times that of the substrate, it is difficult to bend that portion along a curved surface.
