Patent

CA 2666666

This invention provides an organic rare earth metal complex, which emits fluorescence with a wavelength in the range of 550 to 900 nm, particularly a fluorescent resin composition comprising an ethylene-vinyl acetate copolymer containing 0.01 to 10% by mass of an organic rare earth metal complex represented by general formula (see above formula), wherein R represents an aliphatic or aromatic hydrocarbon group; Ln represents a rare earth metal; A represents group -CH=CH-; and n is 0 or 1. There are also provided a solar battery module using the fluorescent resin composition as a sealing material between a front cover and a crystalline silicon cell, and a solar battery with high conversion efficiency.

L'invention concerne un complexe organique de métaux des terres rares, qui émet une fluorescence présentant une longueur d'onde comprise dans la plage de 550 à 900 nm, en particulier une composition de résine fluorescente comprenant un copolymère d'éthylène-acétate de vinyle contenant entre 0,01 et 10% en masse d'un complexe de métaux des terres rares représenté par la formule générale (I), dans laquelle R représente un groupe hydrocarbure aliphatique ou aromatique; Ln représente un métal des terres rares; A représente un groupe -CH=CH-; et n représente 0 ou 1. L'invention concerne également un module de batterie solaire utilisant la composition de résine fluorescente en tant que matériau d'étanchéité entre un couvercle frontal et une cellule au silicium cristallin, ainsi qu'une batterie solaire à rendement de conversion élevé.
