本発明の合わせガラスは、一対のガラス板と、前記一対のガラス板により挟持された前記合わせ前記ガラス用中間膜とからなる。
本発明の太陽電池モジュールは、接着フィルムの接着性が良好で剥離等の不具合が生じにくい。
本発明の接着フィルムは、封止用樹脂と、シランカップリング剤と、pKbが5~12の塩基性化合物(以下、塩基性化合物(A)という。)と、を含む。また、本発明の接着フィルムは、封止用樹脂、シランカップリング剤及び塩基性化合物(A)以外の他の添加剤を含んでもよい。本発明の封止材は、接着フィルムからなる。
封止用樹脂としては、封止材に通常使用される樹脂を使用することができる。
封止用樹脂としては、透明性、加工性及び架橋性に優れる点から、エチレン-極性基含有モノマー共重合体が好ましい。
前記極性基としては、例えば、エステル基(-C(O)O-R又はR-C(O)O-(ただし、Rはアルキル基)等)、カルボキシル基等が挙げられる。
なお、質量平均分子量は、ゲルパーミエーションクロマトグラフィを用いて測定した値である。
封止用樹脂は、1種を単独で使用してもよく、2種以上を併用してもよい。
シランカップリング剤は、太陽電池セル、透明保護材、バックシート等と封止材との接着性を改善する役割を果たす。シランカップリング剤としては、封止材に通常用いられるシランカップリング剤を使用することができる。
シランカップリング剤の具体例としては、例えば、3-メタクリロキシプロピルトリメトキシシラン、3-メタクリロキシプロピルトリメチルジメトキシシラン、アリルトリメトキシシラン、3-グリシドキシプロピルトリメトキシシラン、3-メルカプトプロピルトリメトキシシラン、ビニルトリメトキシシラン、3-グリシドキシプロピルメチルジメトキシシラン、等が挙げられる。
シランカップリング剤は、1種を単独で使用してもよく、2種以上を併用してもよい。
塩基性化合物(A)は、pKbが5~12の塩基性の化合物である。塩基性化合物(A)を用いることで、保管時における封止材中のシランカップリング剤の加水分解反応及び縮合反応の速度を低下させることができる。その結果、封止材を保管している際にシランカップリング剤が経時変化することを抑制できるため、封止材の接着性の低下が抑制される。
なお、pKbは、日本工業規格JIS K 2501中和価測定の電位差滴定法により測定できる。
塩基性化合物(A)は、1種を単独で使用してもよく、2種以上を併用してもよい。
他の添加剤としては、紫外線吸収剤、光安定剤(a)以外の光安定剤、酸化防止剤、架橋剤、架橋助剤、顔料、染料、可塑剤、充填材等が挙げられる。本発明の封止材は、架橋剤を含むことが好ましく、架橋剤及び架橋助剤を含むことがより好ましい。
架橋剤としては、公知の有機過酸化物(パーオキシケタール類、ジアルキルパーオキサイド類、パーオキシエステル類等)、光増感剤等が挙げられる。
架橋助剤としては、例えば、トリアリルイソシアヌレート、トリアリルシアヌレート、トリメチロールプロパントリメタクリレート等が挙げられる。
本発明の封止材におけるシランカップリング剤の含有量は、封止用樹脂の100質量部に対して、0.1~2質量部が好ましく、0.2~1.0質量部がより好ましい。シランカップリング剤の含有量が前記下限値以上であれば、優れた接着性が得られやすい。シランカップリング剤の含有量が前記上限値以下であれば、コスト的に有利である。
本発明の封止材が架橋助剤を含む場合、架橋助剤の使用量は、封止用樹脂100質量部に対して、0質量部超5質量部以下が好ましく、0質量部超2質量部以下がより好ましい。
本発明の封止材の製造方法は、特に限定されず、例えば、封止用樹脂、シランカップリング剤及び塩基性化合物(A)と、必要に応じて使用する他の添加剤を混合して樹脂組成物を得た後に、前記樹脂組成物をシート化する方法等が挙げられる。
シート化方法としては、例えば、Tダイを用いた押出成形法、プレス成形法等が挙げられる。また、樹脂組成物を溶液とする場合、離型シートに樹脂組成物を塗工し、乾燥することにより、シート化することもできる。
以上説明した本発明の封止材においては、特定のpKbの塩基性の低い塩基性化合物(A)が含まれているため、封止材の保管中にシランカップリング剤が加水分解や縮合によって経時変化することが抑制される。また、シランカップリング剤の縮合反応部位の構造や配位数を調節して縮合反応の速度を低下させる必要がないため、シランカップリング剤の接着性が充分に得られる。
以上のことから、本発明の封止材は、長期保管後であっても良好な接着性を有しており、剥離等の不具合が生じにくい太陽電池モジュールを製造することができる。
以下、本発明の太陽電池モジュールの一例について図1に基づいて説明する。
本実施形態の太陽電池モジュール10は、図1に示すように、複数の太陽電池セル11,11・・・と、一対の太陽電池用封止材12,12(以下、封止材12という。)と、透明保護材13と、バックシート14とを備える。
太陽電池セル11は、一対の封止材12,12に挟持されて固定されている。また、封止材12,12は、透明保護材13とバックシート14との間に配置されている。
封止材12は、本発明の封止材である。
太陽電池セル11としては、例えば、p型とn型の半導体を接合した構造を有するpn接合型太陽電池素子が挙げられる。
pn接合型太陽電池素子としては、例えば、シリコン系(単結晶シリコン系、多結晶シリコン系、アモルファスシリコン系等)、化合物系(GaAs系、CIS系、CdTe-CdS系)等が挙げられる。
本実施形態例では、複数の太陽電池セル11は、導線及び半田接合部を備えたタブストリング15を介して電気的に直列に接続されている。
透明保護材13としては、太陽電池モジュールの表面側を保護するために通常使用さていれる部材が使用でき、例えば、ガラス板、樹脂板等が挙げられる。
ガラス板としては、光透過性の点から、表面に凹凸を形成した型板ガラスが好ましい。型板ガラスの材料としては、鉄分の少ない白板ガラス(高透過ガラス)が好ましい。
バックシート14としては、太陽電池モジュールのバックシートとして通常使用されているものが使用できる。
バックシート14の材料としては、例えば、ポリフッ化ビニル、ポリエステル(ポリエチレンテレフタレート等)、ポリオレフィン(ポリエチレン等)、ガラス、金属(アルミニウム等)等が挙げられる。
バックシート14は、単層であってもよく、複層であってもよい。
本発明の太陽電池モジュールの製造方法は、本発明の封止材を用いる以外は公知の製造方法を採用できる。
例えば、太陽電池モジュール10の製造方法としては、以下の方法が挙げられる。
タブストリング15を用いて電気的に接続した複数の太陽電池セル11,11・・・を一対の封止材12,12で挟み、さらに封止材12,12を透明保護材13とバックシート14とで挟む。その後、加熱して、封止材12,12同士、封止材12と透明保護材13、封止材12とバックシート14とを接着する。
以上説明した本発明の太陽電池モジュールは、良好な接着性を有する本発明の封止材を用いるため、剥離等の不具合が生じにくい。
なお、本発明の太陽電池モジュールは、前記した太陽電池モジュール10には限定されない。
例えば、前記接着フィルムからなる合わせガラス用中間膜を用いてもよい。
また、一対のガラス板と、前記一対のガラス板により挟持された前記ガラス用中間膜とからなる合わせガラスを用いてもよい。
