Abstract

La présente invention a trait à un module de cellule solaire qui est doté de multiples cellules solaires sur lesquelles cinq lignes de languette ou plus sont formées. La présente invention a également trait à un procédé permettant de produire ledit module de cellule solaire. Des cellules solaires (12) sont placées sur des feuilles de câblage (16a, 16b), sur lesquelles des électrodes de barre omnibus (14a) sont prévues, et un contact est formé entre les cellules solaires (12) et les électrodes de barre omnibus (14a) qui sont câblées sur les feuilles de câblage (16a, 16b). Par conséquent, il n'est pas nécessaire d'utiliser un ruban de brasure tendre lors de la connexion des cellules solaires en série ni d'utiliser un dispositif de chauffage en vue de chauffer le ruban de brasure tendre comme cela était le cas dans l'art antérieur. En conséquence de quoi, le nombre de lignes de languette qui sont formées sur les cellules solaires (12) n'est plus restreint par le nombre de dispositifs de chauffage, et il est possible de produire un module de cellule solaire (10) qui est doté de multiples cellules solaires (12) sur lesquelles cinq lignes de languette sont formées.
