Title (EN) POLYESTER FILM FOR SOLAR CELL BACK SURFACE PROTECTION FILM
(FR) FILM POLYESTER POUR COUCHE DE PROTECTION DE SURFACE ARRIÈRE DE CELLULE SOLAIRE
(JA) 太陽電池裏面保護膜用ポリエステルフィルム
Abstract:
(EN) Provided is a polyester film for a solar cell back surface protection film for a thin film silicon solar cell, which has excellent durability under high temperature and high humidity. The polyester film for a solar cell back surface protection film is characterized in that: whiteness is 50 or greater; 3‑50 mass% of microparticles, the mean particle size of which is 0.1‑3 µm, are contained; and a film acid value is at least 1 (eq/ton) and not more than 30 (eq/ton).
(FR) L'invention concerne un film polyester pour couche de protection de surface arrière de cellule solaire présentant, pour une cellule solaire à silicium à couche mince, des propriétés excellentes de durée de vie dans des conditions de température et d'humidité élevées. Le film polyester pour couche de protection de surface arrière de cellule solaire se caractérise par le fait que son degré de blancheur est supérieur ou égal à 50; par le fait qu'il possède de 3 à 50% en masse de microparticules dont le diamètre de particule moyen est compris entre 0,1 et 3μm; et par le fait que son indice d'acidité est supérieur ou égal à 1 (eq/ton) et inférieur ou égal à 30 (eq/ton).
(JA) 【課題】薄膜シリコン太陽電池において高温高湿度下での耐久性に優れた太陽電池裏面保護膜用ポリエステルフィルムを提供する。 【解決手段】白色度が50以上で、平均粒径が0.1~3μmの微粒子を3~50質量%含有し、フィルムの酸価が1(eq/ton)以上30(eq/ton)以下であることを特徴とする太陽電池裏面保護膜用ポリエステルフィルム。
