Abstract
(EN) The purpose of the present invention is to provide a solar cell module back sheet, the temperature of which hardly rises by being irradiated with solar rays even if taking on a black color in appearance and the color of which hardly changes even if being used over a long period of time while a cost increase is suppressed. This solar cell module back sheet is equipped with a colored layer including three or more kinds of color materials each having a different hue and a lightness value (L*) of 45 or more, wherein said colored layer has a lightness value (L*) of 40 or less. It is preferable that said three or more kinds of color materials are at least a red color material, a blue color material, and a yellow color material. It is also preferable that the solar cell module back sheet is equipped with a base sheet on which said colored layer is laminated. It is preferable that said base sheet is colored white and said colored layer is laminated on the surface side of said base sheet. It is also preferable that the base sheet is equipped with a base film and a white layer laminated on the surface side of said base film.
(FR) Le but de la présente invention est de fournir une feuille arrière de module de cellule solaire, dont la température s'élève à peine en étant irradiée par des rayons solaires même si elle prend une couleur noire en apparence, et dont la couleur change à peine, même en étant utilisée pendant une longue période de temps, une augmentation de coût étant ainsi supprimée. Cette feuille arrière de module de cellule solaire est pourvue d'une couche colorée comprenant trois ou plusieurs types de matériaux de couleur, chacun ayant une teinte différente et une valeur (L *) de clarté de 45 ou plus, faisant en sorte que ladite couche colorée ait une valeur de clarté (L *) de 40 ou moins. Il est préférable que lesdits trois ou plusieurs types de matériaux de couleur soient au moins un matériau de couleur rouge, un matériau de couleur bleue, et un matériau de couleur jaune. Il est également préférable que la feuille arrière de module de cellule solaire soit équipée d'une feuille de base sur laquelle ladite couche colorée est laminée. Il est également préférable que la feuille de base soit équipée d'un film de base et d'une couche blanche, laminée sur le côté de surface dudit film de base.
(JA)  本発明は、外観上黒色を呈しても太陽光線の照射によって温度上昇がしにくいとともに、コスト高となることを抑制しつつ長期間使用しても変色しにくい太陽電池モジュール用バックシートの提供を目的とするものである。 本発明の太陽電池モジュール用バックシートは、互いに色相の異なる明度L45以上の三種以上の色料を含む着色層を備え、上記着色層の明度Lが、40以下である構成を備える。この三種以上の色料は、少なくとも赤色系色料、青色系色料及び黄色系色料であることが好ましい。さらに、この着色層が積層される基材シートを備えることが好ましい。この基材シートは白色で、この基材シートの表面側に上記着色層が積層されていることが好ましい。また、基材シートは、基材フィルムとこの基材フィルムの表面側に積層される白色層とを備えることが好ましい。
