Title
(EN) SOLAR CELL MODULE
(FR) MODULE DE CELLULES SOLAIRES
Abstract
(EN)
A solar cell module comprises a light transmissive element, a front encapsulation layer, a plurality of solar cells spaced apart from each other, a post encapsulation layer, and a back sheet disposed in a thickness direction of the solar cell module in turn. The solar cell module further includes a light redirecting film which comprises a concave-convex reflective structure, and the concave-convex reflective structure includes an array of abutting triangular prisms. An angle between an orthographic projection of an orientation direction of the array of abutting triangular prisms on the back sheet and an orthographic projection of the solar cell strings on the back sheet is in a range of 45-80 degrees. A vertical distance between a plane where apexes of the concave-convex reflective structure are located and a plane where the solar cells are located is in a range of 200 - 600 μm. The solar cell module can achieve high power generation efficiency while satisfying safety.

L'invention concerne un module de cellules solaires comprenant un élément de transmission de lumière, une couche d'encapsulation avant, une pluralité de cellules solaires espacées les unes des autres, une couche de post-encapsulation, et une feuille arrière disposée dans une direction d'épaisseur du module de cellules solaires à son tour. Le module de cellules solaires comprend en outre un film de redirection de lumière qui comprend une structure réfléchissante concave-convexe, et la structure réfléchissante concave-convexe comprend un réseau de prismes triangulaires contigus. Un angle entre une projection orthographique d'une direction d'orientation du réseau de prismes triangulaires adjacents sur la feuille arrière et une projection orthographique des chaînes de cellules solaires sur la feuille arrière est dans une plage de 45 à 80 degrés. Une distance verticale entre un plan où les sommets de la structure réfléchissante concave-convexe sont situés et un plan où les cellules solaires sont situées est dans une plage de 200 à 600 µm. Le module de cellules solaires peut atteindre une efficacité de génération de puissance élevée tout en satisfaisant la sécurité.
