Title
(EN) ADHESIVE COMPOSITION, LIGHT REDIRECTING FILM AND SOLAR CELL MODULE
(FR) COMPOSITION ADHÉSIVE, FILM DE REDIRECTION DE LUMIÈRE ET MODULE DE CELLULE SOLAIRE
Abstract
(EN)
An adhesive composition comprises a resin base material, a peroxide crosslinking agent, a non-peroxide crosslinking agent, a coupling agent, an ultraviolet absorber, and an ultraviolet stabilizer, wherein the adhesive composition undergoes an exothermic reaction at a temperature of 95°C or more and has an exothermic amount of 2-40 J/g. The invention further provides a light redirecting film which comprises a reactive adhesive layer comprising the adhesive composition. Furthermore, the invention further provides a solar cell module comprising the light redirecting film. When the adhesive composition according to the present invention is used as an adhesive layer for adhering a light redirecting film to a back sheet during the assembly of a solar cell module, the formation of bulges in the adhesive layer during high moisture-heat aging may be avoided while maintaining the high adhesion of the adhesive layer, and the relative positional drift of the light redirecting film during the high temperature laminating process may be greatly reduced.
(FR)
La présente invention concerne une composition adhésive qui comprend un matériau de base de résine, un agent de réticulation peroxyde, un agent de réticulation non peroxyde, un agent de couplage, un absorbeur d'ultraviolets et un stabilisant vis-à-vis des ultraviolets, la composition adhésive subissant une réaction exothermique à une température de 95 °C ou plus et ayant une quantité exothermique de 2 à 40 J/g. L'invention concerne en outre un film de redirection de lumière qui comprend une couche adhésive réactive comprenant la composition adhésive. En outre, l'invention concerne également un module de cellule solaire comprenant le film de redirection de lumière. Lorsque la composition adhésive selon la présente invention est utilisée en tant que couche adhésive pour coller un film de redirection de lumière à une feuille de support pendant l'assemblage d'un module de cellule solaire, la formation de bosses dans la couche adhésive pendant le vieillissement thermique à humidité élevée peut être évitée tout en maintenant l'adhérence élevée de la couche adhésive, et la dérive positionnelle relative du film de redirection de lumière pendant le processus de stratification à haute température peut être fortement réduite.
