Description
(1)有機過酸化物が、ジアルキルパーオキサイド系化合物である。
エチレン−メタクリル酸メチル共重合体(EMMA)は、モノマーとしてエチレン及びメタクリル酸メチル(MMA)を用いて得られる共重合体であり、本発明において、エチレン−メタクリル酸メチル共重合体におけるメタクリル酸メチルの含有率は25〜35質量%、好ましくは25〜30質量%である。25質量%より低いと透明性が低下する場合があり、35質量%より高いと加工性が低下する場合がある。
本発明において架橋剤は、エチレン−メタクリル酸メチル共重合体の架橋構造を形成することができるものである。架橋剤としては、接着力、耐湿性、耐貫通性の温度依存性が改善された封止膜が得られることから、有機過酸化物を用いる。
本発明に使用するシランカップリング剤は、メタクリロキシ系シランカップリング剤(メタクリロキシ基を含むシランカップリング剤のことをいう。)である。例えば、γ−メタクリロキシプロピルトリメトキシシラン、γ−メタクリロキシプロピルメチルジエトキシシラン、γ−メタクリロキシプロピルトリエトキシシラン、γ−メタクリロキシプロピルメチルジメトキシシランが好ましく、中でもγ−メタクリロキシプロピルトリメトキシシランが特に好ましい。これらシランカップリング剤は、単独で使用しても、又は2種以上組み合わせて使用しても良い。
架橋硬化前の太陽電池用封止膜は、更に架橋助剤を含んでいてもよい。前記架橋助剤は、エチレン−メタクリル酸メチル共重合体の架橋密度を向上させ、封止膜の接着性及び耐久性を更に向上させることができる。
上述した本発明の太陽電池用封止膜を形成するには、公知の方法に準じて行えばよい。例えば、上述した各成分を含む組成物を、通常の押出成形、又はカレンダ成形(カレンダリング)等により成形してシート状物を得る方法により製造することができる。また、前記組成物を溶剤に溶解させ、この溶液を適当な塗布機(コーター)で適当な支持体上に塗布、乾燥して塗膜を形成することによりシート状物を得ることもできる。尚、製膜時の加熱温度は、架橋剤が反応しない或いはほとんど反応しない温度とすることが好ましい。例えば、50〜90℃、特に40〜80℃とするのが好ましい。本発明の太陽電池用封止膜の厚さは特に制限されないが、0.05〜2mmである。
本発明の太陽電池の構造は、本発明の太陽電池用封止膜を用いていれば、特に制限されない。例えば、表面側透明保護部材と裏面側保護部材との間に、本発明の太陽電池用封止膜を介在させて架橋一体化させることにより太陽電池用セルを封止させた構造などが挙げられる。なお、本発明において、太陽電池セルの光が照射される側(受光面側)を「表面側」と称し、太陽電池セルの受光面とは反対面側を「裏面側」と称する。
表1〜5に示す配合で各材料をロールミルに供給し、70℃において混練して太陽電池用封止膜組成物を調製した。前記太陽電池用封止膜組成物を、70℃において、カレンダ成形し、放冷後、太陽電池用封止膜を作製した。
(1)初期のガラス接着力
3mmのフロートガラス上に上記の太陽電池用封止膜(厚さ0.6mm)を載置し、100℃に設定した真空ラミネーターで10分加圧して仮圧着した後、この積層体を155℃に設定したオーブンで45分架橋させた。この積層体について、JIS K 6854に従い、図2に示すように、ガラス板21と太陽電池用封止膜23との間の一部を剥離して、太陽電池用封止膜23を180°折り返して引張試験機(島津製作所社製、オートグラフ)を用いて引張速度100mm/分時の引き剥がし力をガラス接着力(N/cm)として測定した。
(2)耐湿熱性試験後のガラス接着力
(1)と同様にして作製した積層体を、85℃、85%の環境に設定した湿熱オーブン内に4000時間静置した後、ガラス接着力を(1)と同様にして測定した。
(3)発泡試験
上記太陽電池用封止膜(厚さ0.6mm)を、ガラス(表面側保護部材)/太陽電池用封止膜/太陽電池素子/太陽電池用封止膜/裏面側保護部材(ポリアミド樹脂製バックシート:ISOVOLTA社製、ICOSOLAR3554)の順で積層し、100℃に設定した真空ラミネーターで10分加圧して仮圧着した積層体を、155℃に設定したオーブンに入れ、フクレが発生するまでの時間を計測した。
(4)光線透過率
2枚の離型PET(厚さ100μm)で太陽電池用封止膜(厚さ0.6mm)を挟持した積層体を、90℃条件にて真空2分、プレス8分の真空ラミネーターによる仮圧着工程を経て、155℃に設定したオーブンにて45分間架橋させた。この積層体について、分光光度計(U−4100:日立製作所製)にて300〜1200nmのスペクトル測定を実施し、その平均値を光線透過率とした。
表1及び2に示されているように、実施例の太陽電池用封止膜は、比較例と比べ、発泡が抑制され、初期の接着力が高く、耐湿熱性条件下での接着力の低下が小さいことが認められた。特に、架橋剤/シランカップリング剤の質量比が0.2〜0.5である実施例3,8,9,14,19及び20の封止膜は発泡が顕著に抑えられ、接着力が特に高いことが示されている。なお、表における架橋剤/シランカップリング剤の質量比の値は、小数点第2位を四捨五入した値である。また、実施例の太陽電池用封止膜の光線透過率は、従来から使用されているEVAを用いた封止膜(比較例1〜8)と同等の値を有しており、封止膜として使用するのに適していることが示された。
