Definitions
- the present invention relates to a method for manufacturing a solar cell module in which connection electrodes of a plurality of solar cells are connected by tab wires, and a solar cell module.
- Solar cells are attracting attention as a new environment-friendly energy source because they can directly convert sunlight, which is a clean and inexhaustible energy source, into electricity.
- the output per solar cell is about several watts, so it is not used for each solar cell, but output by connecting a plurality of solar cells in series. Is used as a solar cell module whose power is increased to 100 W or more.
- a plurality of adjacent solar cells are connected by tab wires made of solder-coated ribbon-like copper foil.
- one end side of the tab wire is connected to the front surface electrode of one solar battery cell, and the other end side is connected to the back surface electrode of the adjacent solar battery cell so that each solar battery cell is connected in series.
- connection between the solar battery cell and the tab wire is made up of a bus bar electrode formed by screen printing of silver paste on the light receiving surface of the solar battery cell, an Ag electrode formed on the back surface connection portion of the solar battery cell, and a tab.
- the wires are connected by soldering.
- region other than a connection part is formed with the Al electrode on the back surface of the photovoltaic cell.
- the plurality of solar cells are protected by covering the bus bar electrode side with a surface cover via a sheet of sealing resin and covering the back electrode side with a back sheet via a sheet of sealing resin.
- a tab wire having a thickness of 0.1 mm to 0.2 mm is used in the solar cell module.
- the output of the solar cell module is reduced due to the electrical resistance of the tab wire itself.
- the thickness of the tab wire is increased, the electrical resistance of the tab wire itself is lowered, so that the output of the solar cell module can be improved.
- the stress due to expansion and contraction of the tab wire increases. End up. For this reason, in soldering, there are concerns about cracking of the solar cells, peeling of the tab wires, and deterioration of long-term reliability when the tab wires are connected.
- a method of connecting the tab wire, the bus bar electrode, and the back electrode there is a method of using a conductive adhesive film that can be connected by a thermocompression treatment at a temperature lower than soldering (see, for example, Patent Document 1). .

次に、太陽電池モジュール1の各構成について説明する。太陽電池モジュール1は、上述したように複数の太陽電池セル2を備える。
第1のシート10及び第2のシート11は、第1の封止樹脂層及び第2の封止樹脂層に相当するものである。この第1のシート10及び第2のシート11は、例えば、エチレンビニルアセテート樹脂(EVA)、ウレタン樹脂等からなるシート状の透光性封止材である。この第1のシート10及び第2のシート11は、マトリクス9と表面カバー12との間、マトリクス9とバックシート13との間に介在し、マトリクス9に表面カバー12及びバックシート13を接着する。また、この第1のシート10及び第2のシート11は、タブ線6の周囲を覆っており、タブ線6が熱により伸縮した際に、このタブ線6の伸縮による応力を吸収し、タブ線6の剥離及び太陽電池セル2にクラックが発生することを防止する。
表面カバー12は、例えば、ガラスや透光性プラスチック等の透光性の材料が用いられる。また、バックシート13は、ガラスやアルミニウム箔を樹脂フィルムで挟持した積層体等が用いられる。

実施例8では、図8に示すような、タブ線の両面に、凹凸部が形成されたものを用い、バスバー電極及び裏面電極に凹凸部が接続するようにタブ線の厚み(A)、第1のシート及び第2のシートのそれぞれの厚み(B)、厚みの比(B/A)を表1に示すようにしたこと以外は、実施例1と同様にして太陽電池モジュールを作製した。
比較例1~比較例5は、タブ線の厚み(A)、第1のシート及び第2のシートのそれぞれの厚み(B)、厚みの比(B/A)を表2に示すようにしたこと以外は、実施例1と同様にして太陽電池モジュールを作製した。
比較例6、7では、バスバー電極及び裏面電極と、タブ線との接続を半田づけにより行い、タブ線の厚み(A)、第1のシート及び第2のシートのそれぞれの厚み(B)、厚みの比(B/A)を表2に示すようにしたこと以外は、実施例1と同様にして太陽電池モジュールを作製した。
ラミネート性の評価は、表面カバー及びバックシートの周囲から第1のシート及び第2のシートを構成するEVA樹脂がはみ出している部分において、最もはみ出している部分の大きさで評価した。表1及び表2において、最大のはみ出し量が0mm以上、1.5mm未満の場合には◎で示し、はみ出し量が1.5mm以上、3.0mm未満の場合には○で示し、はみ出し量が3.0mm以上の場合には×で示した。また、第1のシート及び第2のシート中に気泡が残存しているかどうかを目視にて確認し、残存している場合には、△で示した。
発電効率の評価は、発電効率測定機器としてソーラーシュミレーター(日清紡メカトロニクス株式会社製 型式PVS1116i)を用いて発電効率を測定し、評価した。測定条件は、JIS C8913(結晶系太陽電池セル出力測定方法)に準拠して行った。表1及び表2において、初期の発電効率が16.30%以上の場合には◎で示し、発電効率が16.00%以上、16.29%以下の場合には○で示し、発電効率が15.70%以上、15.99%以下の場合には△で示し、発電効率が15.69%以下の場合には×で示した。
