Title (EN) MULTILAYER FILM AND PHOTOVOLTAIC MODULE INCLUDING SAME
(FR) FILM MULTICOUCHE ET MODULE PHOTOVOLTAÏQUE INCLUANT LEDIT FILM
(KO) 다층 필름 및 이를 포함하는 광전지 모듈
Abstract: front page image
(EN)The present invention relates to a multilayer film, to a back sheet for a photovoltaic module, to a method for manufacturing same, and to a photovoltaic module. The multilayer film of the present invention is prepared by forming a resin layer on a base material, wherein the resin layer includes a fluorine-based polymer and a polymer having oxazoline groups. Thus, the resin layer including the fluorine-based polymer can have superior durability and weather resistance, and also have strong interfacial adhesion with the base material. In the process for manufacturing the multilayer film, a drying process can be performed at a relatively low temperature, thereby reducing manufacturing costs, improving productivity, and preventing deterioration in quality by thermal deformation and thermal shocks. The multilayer film of the present invention can be used effectively, for example, as a back sheet for various types of photovoltaic modules.
(FR)La présente invention concerne un film multicouche, une feuille arrière pour un module photovoltaïque, un procédé de fabrication de celui-ci, et un module photovoltaïque. Le film multicouche de la présente invention est préparé en formant une couche de résine sur un matériau de base, la couche de résine incluant un polymère à base de fluor et un polymère ayant des groupes oxazoline. Ainsi, la couche de résine incluant le polymère à base de fluor peut avoir une durabilité supérieure et une résistance aux intempéries supérieure, et avoir aussi une forte adhérence interfaciale avec le matériau de base. Dans le procédé de fabrication du film multicouche, un procédé de séchage peut être effectué à une température relativement basse, en réduisant de cette façon les coûts de fabrication, en améliorant la productivité, et en prévenant la détérioration de la qualité par déformation thermique et chocs thermiques. Le film multicouche de la présente invention peut être utilisé efficacement, par exemple, comme feuille arrière pour divers types de modules photovoltaïques.
(KO)본 발명은 다층 필름, 광전지 모듈용 이면 시트, 그 제조 방법 및 광전지 모듈에 관한 것이다. 본 발명의 다층 필름은, 불소계 고분자 및 옥사졸린기 함유 고분자를 포함하는 수지층을 기재 상에 형성함으로써, 불소계 고분자를 포함하는 수지층이 우수한 내구성 및 내후성을 가지는 동시에, 기재와 높은 계면 접착력을 발휘할 수 있다. 또한, 본 발명에서는, 상기 다층 필름의 제조 과정에서 건조 공정을 비교적 저온에서 진행할 수 있도록 하여, 제조 비용을 줄이고, 생산성을 높이며, 열변형 또는 열충격 등에 의한 제품의 품질 저하를 방지할 수 있다. 이와 같은, 본 발명의 다층 필름은, 예를 들면, 다양한 형태의 광전지 모듈에서 이면 시트로서 효과적으로 사용될 수 있다.
