熱接着性層12における他の樹脂の含有率は、0~20質量%程度である。
次に、図1を参照して、太陽電池モジュール用保護シート10の製造方法について説明する。
太陽電池モジュール用保護シート10を製造するには、Tダイ押出機やTダイ製膜機を用いた押出成形により、熱接着層を形成する樹脂材料を溶融・混練し、基材フィルム11を一定の速度にて移動させながら、その基材フィルム11の一方の面11aに、溶融した樹脂材料を押し出して積層し、基材フィルム11の一方の面11aに、樹脂材料からなる熱接着性層12を形成し、太陽電池モジュール用保護シート10を得る。
図2は、本発明の太陽電池モジュール用保護シートの第二の実施形態を示す概略断面図である。
図2において、図1に示した太陽電池モジュール用保護シート10と同じ構成要素には同一の符号を付して説明を省略する。
この実施形態の太陽電池モジュール用保護シート20は、第一の実施形態と同様に、太陽電池モジュールのフロントシートまたはバックシートに適用される。
この実施形態では、基材フィルム11および熱接着性層12は、第一の実施形態と同様な構成である。
蒸着層13を形成する蒸着方法としては、例えば、プラズマ化学気相成長法、熱化学気相成長法、光化学気相成長法などの化学気相法、または、真空蒸着法、スパッタリング法、イオンプレーティング法などの物理気相法が用いられる。これらの方法の中でも、操作性や層厚の制御性を考慮した場合、スパッタリング法が好ましい。
これらの金属の酸化物、窒化物、酸窒化物としては、例えば、酸化ケイ素、酸化アルミニウム、酸化スズ、窒化珪素、酸窒化珪素、酸窒化アルミニウムなどが挙げられる。
蒸着層13が複数種の無機材料からなる場合、各無機材料からなる層が順に蒸着された積層構造の蒸着層であってもよく、複数種の無機材料が同時に蒸着された蒸着層であってもよい。
図3は、本発明の太陽電池モジュール用保護シートの第三の実施形態を示す概略断面図である。
図3において、図1に示した太陽電池モジュール用保護シート10、および、図2に示した太陽電池モジュール用保護シート20と同じ構成要素には同一の符号を付して説明を省略する。
この実施形態の太陽電池モジュール用保護シート30は、第一の実施形態および第二の実施形態と同様に、太陽電池モジュールのフロントシートまたはバックシートに適用される。
この実施形態では、基材フィルム11および熱接着性層12は、第一の実施形態と同様な構成であり、蒸着層13は、第二の実施形態と同様な構成である。
この接着層を構成する接着剤としては、ポリアクリル系接着剤、ポリウレタン系接着剤、エポキシ系接着剤、ポリエステル系接着剤、ポリエステルポリウレタン系接着剤などが用いられる。これらの接着剤は1種を単独で用いてもよく、2種以上を組み合わせて用いてもよい。
PVFを主成分とする樹脂としては、例えば、「Tedlar(商品名、E.I.du Pont de Nemours and Company社製)」が用いられる。
ECTFEを主成分とする樹脂としては、例えば、「Halar(商品名、Solvay Solexis社製)」が用いられる。
ETFEを主成分とする樹脂としては、例えば、「Fluon(商品名、旭硝子社製)」が用いられる。
塗料に含まれるフッ素含有樹脂としては、硬化性官能基を有するフルオロオレフィン樹脂を用いることが好ましい。このフルオロオレフィン樹脂としては、テトラフルオロエチレン(TFE)、イソブチレン、フッ化ビニリデン(VdF)、ヒドロキシブチルビニルエーテルおよびその他のモノマーからなる共重合体、並びに、TFE、VdF、ヒドロキシブチルビニルエーテルおよびその他のモノマーからなる共重合体が用いられる。
これらの中でも、耐候性および顔料分散性などの観点から、CTFEを主成分としたポリマーおよびTFEを主成分としたポリマーが好ましく、「LUMIFLON」および「ZEFFLE」が最も好ましい。
「ZEFFLE」は、TFEと有機溶媒可溶性の炭化水素オレフィンとの共重合体であり、なかでも反応性の高い水酸基を備えた炭化水素オレフィンを含むものが、溶剤可溶性、架橋反応性、基材密着性および顔料分散性に優れるので好ましい。
三元重合体としては、例えば、VdFとTFEとヘキサフルオロプロピレンとの三元重合体である「Dyneon THV(商品名、3M Company社製)」が用いられる。このような三元重合体は、それぞれのモノマーが有する特性を樹脂に付与することができるので好ましい。例えば、「Dyneon THV」は、比較的低温で製造することができ、エラストマーや炭化水素ベースのプラスチックにも接着でき、柔軟性や光学的透明度にも優れるので好ましい。
このような溶媒のなかでも、塗料中の含有成分の溶解性および塗膜中への残留性の低さ(低い沸点温度)の観点から、溶媒としては、キシレン、シクロヘキサノンまたはMEKから選択されるいずれか1種または2種以上の有機溶媒を含む溶媒が好ましい。
架橋剤としては、本発明の効果を損なうものでなければ特に限定されず、金属キレート類、シラン類、イソシアネート類またはメラミン類が好適に用いられる。バックシート20を屋外において30年以上使用することを想定した場合、耐候性の観点から、架橋剤としては、脂肪族のイソシアネート類が好ましい。
この組成物の組成比は、塗料全体を100質量%としたとき、フッ素含有樹脂の含有率は3~80質量%が好ましく、25~50質量%がより好ましく、顔料の含有率は5~60質量%が好ましく、10~30質量%がより好ましく、溶媒の含有率は20~80質量%が好ましく、25~65質量%がより好ましい。
また、触媒としては、例えば、ジブチルジラウリン酸スズが用いられ、この触媒はフッ素含有樹脂とイソシアネートとの架橋を促進するために用いられる。
蒸着層13に塗布した塗料の乾燥温度は、本発明の効果を損なわない温度であればよく、蒸着層13および基材フィルム11への影響を低減する観点からは、50~130℃の範囲であることが好ましい。
図4は、本発明の太陽電池モジュール用保護シートの第四の実施形態を示す概略断面図である。
図4において、図1に示した太陽電池モジュール用保護シート10と同じ構成要素には同一の符号を付して説明を省略する。
この実施形態の太陽電池モジュール用保護シート40は、第一の実施形態と同様に、太陽電池モジュールのフロントシートまたはバックシートに適用される。
この実施形態では、基材フィルム11および熱接着性層12は、第一の実施形態と同様な構成である。
接着層15を構成する接着剤としては、ポリアクリル系接着剤、ポリウレタン系接着剤、エポキシ系接着剤、ポリエステル系接着剤、ポリエステルポリウレタン系接着剤などが用いられる。これらの接着剤は1種を単独で用いてもよく、2種以上を組み合わせて用いてもよい。
図5は、本発明の太陽電池モジュール用保護シートの第五の実施形態を示す概略断面図である。
図5において、図1に示した太陽電池モジュール用保護シート10および、図4に示した太陽電池モジュール用保護シート40と同じ構成要素には同一の符号を付して説明を省略する。
この実施形態の太陽電池モジュール用保護シート50は、第一の実施形態および第四の実施形態と同様に、太陽電池モジュールのフロントシートまたはバックシートに適用される。
この実施形態では、基材フィルム11および熱接着性層12は、第一の実施形態と同様な構成であり、接着層15および金属シート16は、第四の実施形態と同様な構成である。
フッ素樹脂層17の厚みは、耐候性、耐薬品性、軽量化などを考慮して設定され、5μm~50μmの範囲が好ましく、10μm~30μmの範囲がより好ましい。
図6は、本発明の太陽電池モジュールの一実施形態を示す概略断面図である。
太陽電池モジュール100は、結晶シリコン、アモルファスシリコンなどからなる太陽電池セル101と、太陽電池セル101を封止する電気絶縁体からなる封止材(充填層)102と、封止材102の表面に積層された表面保護シート(フロントシート)103と、封止材102の裏面に積層された裏面保護シート(バックシート)104とから概略構成されている。
ポリオレフィン系樹脂としては、低密度ポリエチレン(LDPE、密度:0.910g/cm3以上、0.930g/cm3未満)、中密度ポリエチレン(MDPE、密度:0.930g/cm3以上、0.942g/cm3未満)、高密度ポリエチレン(HDPE、密度:0.942g/cm3以上)などのポリエチレン、ポリプロピレン(PP)、オレフィン系エラストマー(TPO)、シクロオレフィン系樹脂、エチレン-酢酸ビニル共重合体(EVA)、エチレン-酢酸ビニル-無水マレイン酸共重合体、エチレン-(メタ)アクリル酸共重合体、エチレン-(メタ)アクリル酸エステル-無水マレイン酸共重合体などが用いられる。
このようにすれば、第一~第五の実施形態の太陽電池モジュール用保護シートの熱接着性層12と封止材102との親和性が大きくなり、熱接着性層12と封止材102との大きな接合力が得られる。
この実施形態では、太陽電池モジュール100は、上述の第一~第五の実施形態における太陽電池モジュール用保護シートが、フロントシート103およびバックシート104として設けられたものである。
さらに、太陽電池モジュールを構成する太陽電池セルにフレキシブル基板を用い、上記の第一~第五の実施形態の太陽電池モジュール用保護シートをフロントシートおよびバックシートとして設けることにより、フレキシブル性を有する太陽電池モジュールを得ることができる。このように、太陽電池モジュールをフレキシブル化することにより、ロールtoロールで大量生産することが可能となる。また、フレキシブル性を有する太陽電池モジュールは、アーチ状や放物線状の壁面を有する物体にもフィットさせることができるので、ドーム状の建築物や高速道路の防音壁などに設置することが可能となる。
