本発明は太陽電池モジュール、特に各電極と外部リード
線との接続部を改良した太陽電池モジュールに関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a solar cell module, and particularly to a solar cell module in which the connection between each electrode and an external lead wire is improved.
従来例の構成とその問題点
最近エネルギー供給の一手段として太陽電池が注目され
ている。その理由は無限ともいえるクリーンな太陽エネ
ルギーから直接電気エイ・ルギーが容易に取り出せるか
らである。しかしながら現在では上記電気エネルギー製
造原価が高いため充分に普及する段階にまで至ってい々
い。しかし上記利点を応用した太陽電池モジュールが出
始め、次第に普及する兆が見えている。Conventional configurations and their problems Recently, solar cells have been attracting attention as a means of energy supply. The reason for this is that electricity can be easily generated directly from the almost limitless clean solar energy. However, at present, due to the high cost of producing the above-mentioned electrical energy, it has not reached the stage where it is sufficiently widespread. However, solar cell modules that take advantage of the above advantages have begun to appear, and there are signs that they will gradually become popular.

あった。In planning the practical use of solar cells, it is of course important to reduce the cost of electricity produced by them, but it is also important to extend the usable life of the solar cell modules as long as possible. There must be. That is, the product must have high long-term reliability, and although efforts have been made to improve the reliability and long-term life of solar cell modules, there are still some points that cannot be said to be sufficient.
例えば従来の太陽電池モジュールにおいて信頼性を低下

一つに太陽電池素子から外部へ電気を取り出すだめの接
続部分の強度不足があげられる。For example, several drawbacks have been pointed out that cause a decrease in reliability in conventional solar cell modules, one of which is the lack of strength at the connecting portions that extract electricity from the solar cell elements to the outside.

）入り銀電極に外部端子用の薄い板状のＩＪ−ド線捷た
はより線のリード線を半田付けする方法が提案された。Electricity generated by a solar cell element is collected at its positive and negative poles, and conventionally, thin plate-shaped lead wires or stranded 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 connection parts, each of the positive and negative electrodes is once connected to a silver electrode containing a glass frit, and the glass frit IJ7
) A method was proposed in which a thin plate-shaped IJ-cord lead wire for an external terminal was soldered to a silver electrode containing twisted or stranded wire.

と１〜、経済的にも不利となっている。In this case, the external terminal can be soldered to the glass frit-filled silver electrode, which improves the strength of the connection somewhat.
Reliability has improved and mechanized processing has become possible, but the process of forming silver electrodes with glass frits is added, which not only increases process costs, but also requires heat fusing at a temperature of at least 400°C. solar type 1' due to heat.
It has a negative impact on the pond and requires a lot of energy, making it economically disadvantageous.

点がある。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 placed around it. A conductive metal plate is bonded on both the conductive adhesive layer and the insulating adhesive layer, and thus each electrode and the conductive metal plate are electrically connected through the conductive adhesive layer. A solar cell module has been proposed in which the lead wires are connected to the metal plate and firmly bonded via the insulating adhesive layer, and lead wires are soldered onto the metal plate. 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. Damage, etc. is reduced, the life of the solar cell module is extended, and reliability is improved. Once a module with this structure is completed, it is highly reliable and has a long lifespan as described above, but it is important to keep the insulating adhesive layer at an appropriate thickness and then glue the conductive metal plate. Difficult and sometimes short-circuited. It has the disadvantage that it is difficult to manufacture by kneading and the yield is reduced.
