Abstract

L'invention concerne un module photovoltaïque, comprenant une plaque de couvercle (10), une pellicule adhésive de couche supérieure (20), une chaîne de batteries (30), une pellicule adhésive de couche inférieure (40) et une plaque arrière (50) qui sont disposées de haut en bas dans cet ordre. La chaîne de batteries comprend un élément de batterie (31) et un organe connecteur (32) pour la connexion de l'élément de batterie, et l'élément de batterie est placé de manière inclinée ou perpendiculaire par rapport à la plaque de couvercle ou à la plaque arrière. Par conséquent, les dimensions de longueur et de largeur du module restant inchangées, un grand nombre d'éléments de batteries peuvent être encapsulés dans le module de sorte que l'aire efficace totale des éléments de batteries est équivalente ou supérieure à l'aire du module, aidant ainsi à améliorer le rendement de conversion du module.
