利点を応用した太陽電池モジユールが出始め、次
第に普及する兆が見えている。Conventional configuration and its problems Recently, solar cells have been attracting attention as a means of energy supply. The reason for this is that electrical energy can be easily extracted directly from the almost infinite amount of clean solar energy. However, due to the high cost of producing the electrical energy, it has not yet reached a stage where it is fully widespread. However, solar cell modules that utilize the above-mentioned advantages have begun to appear, and there are signs that they will gradually become popular.

つた。 In planning to put solar cells into practical use, it is of course important to reduce the cost of the electricity produced by them, but it is also important to ensure that the usable life of the solar cell modules produced is as long as possible. Must be. That is, the long-term reliability of the product must be high, and for this reason, efforts have been made to improve the reliability and long-term life of solar cell modules, but there are still some points that cannot be said to be sufficient.

モジユールへの悪影響とそのためのエネルギーを
必要とし、経済的にも不利となつている。 Electricity generated by a solar cell element is collected at its positive and negative poles, and conventionally, thin plate-shaped lead wires or stranded wire lead wires were connected directly to each electrode using silver paint. Such a connection part lacks mechanical strength and is problematic in use, which causes a decrease in reliability. As a means to improve the lack of strength of such conventional connections,
A method has been proposed in which each of the positive and negative electrodes is once connected to a glass frit-filled silver electrode, and a thin plate-shaped lead wire or stranded lead wire for an external terminal is soldered to the glass frit-filled silver electrode. In this case, external terminals could be soldered to the glass fritted silver electrode, which improved the strength and reliability of the connection to some extent, and made mechanization possible, but the process of forming the glass fritted silver electrode This not only increases the process cost, but also requires heat fusing treatment at a temperature of at least 400°C, which has an adverse effect on the solar cell module due to heat and requires energy, which is economically disadvantageous. It is becoming.

がある。 Furthermore, as another means to improve the lack of strength of conventional connections, a conductive adhesive layer is provided on a portion of the positive and negative electrodes of the solar cell element, and an insulating adhesive layer is provided around it. , a conductive metal plate is bonded on both the conductive adhesive layer and the insulating adhesive layer, and thus each of the electrodes and the conductive metal plate are electrically connected via the conductive adhesive layer. A solar cell module has been proposed in which the metal plates are connected and firmly bonded via the insulating adhesive layer, and lead wires are soldered to the metal plates. In this case, the external lead wire is electrically connected to the positive and negative electrodes of the solar cell element with a conductive adhesive and a thin conductive metal plate, and at the same time, the external lead wire is connected with a conductive metal plate and a thin conductive metal plate with an insulating adhesive layer. Since each electrode is firmly connected, and the lead wire itself is soldered to a conductive metal plate, it has superior strength compared to the conventional structure in which the lead wire is attached directly to each electrode. There will be less damage, the lifespan of the solar cell module will be longer, and the reliability will be improved. Once a module with this structure is completed, it is highly reliable and has a long life as described above, but it is difficult to bond the conductive metal plate while maintaining the insulating adhesive layer at an appropriate thickness. , sometimes short-circuited. In other words, it has the disadvantage that it is difficult to manufacture and the yield is reduced.

る。Effects of the Invention In the solar cell module according to the present invention, the external lead wire is electrically connected to the positive and negative electrodes of the solar cell element using a conductive adhesive, metal foil laminated to an insulating resin plate, or solder. At the same time, the insulating resin plate with metal foil is firmly adhered to the solar cell element with an insulating adhesive. Therefore, compared to the conventional structure in which lead wires are attached directly to each electrode,
Needless to say, it has excellent strength. As a result, damage and the like are reduced, the life of the solar cell module is extended, and reliability is improved. Further, a conductive adhesive layer is provided on a part of the positive electrode and the negative electrode of the solar cell element described above, and an insulating adhesive layer is provided around it, and the conductive adhesive layer and the insulating adhesive layer are provided around the conductive adhesive layer. A conductive metal is bonded on both layers of the conductive metal plate, thereby electrically connecting each of the electrodes and the conductive metal plate through the conductive adhesive layer and firmly connecting the electrodes with the conductive metal plate through the insulating adhesive layer. There is no longer any need to maintain an appropriate thickness of the insulating adhesive layer, which was difficult during the manufacture of solar cell modules, which involves bonding and further soldering lead wires onto the metal plates, thereby eliminating short-circuit accidents. There is no such thing, and the yield improves. Manufacturing is also much easier.

い。 In the present invention, if the insulating resin plate to which the metal foil is bonded is widened, even if the adhesive strength of the thin film constituting the element to the substrate is minute, a large adhesive strength can be obtained overall. Of course, no matter how wide the insulating plate is made, there is no fear of short circuit with the element.
