Abstract
(EN)
Disclosed is a densely-arranged solar cell string and a preparation method, and an assembly and a system thereof. The preparation method mainly comprises the steps of: manufacturing a solar cell, H-shaped electrodes being formed on front and back surfaces of the cell, a main grid (11) being a segmented electrode, and a welding point being arranged on one end of the main grid (11); printing a strip hot melt glue (13) at the position of the welding point in a direction perpendicular to the main grid (11), with the welding point emerging from the hot melt glue; cutting the cell, along a cell cutting region (12), into a plurality of smaller cells; coating the position of the welding point of the main grid (11) on the front surface of each of the smaller cells with a conductive adhesive or soldering paste (14); superposing the welding point of the main grid (11) on the back surface of one of the smaller cells onto that of the main grid (11) on the front surface of another one of the smaller cells, and then heating same, so that the two smaller cells are electrically connected by means of the conductive adhesive or the soldering paste (14); and sequentially connecting the plurality of smaller cells to form the solar cell string. The method increases the utilization area of the cells in an active region of the assembly and increases the power of the assembly.

L'invention concerne une chaîne de cellules solaires agencées de manière dense et un procédé de préparation, et un ensemble ainsi qu'un système associés. Le procédé de préparation comprend principalement les étapes consistant à : fabriquer une cellule solaire, des électrodes en forme de H étant formées sur les surfaces avant et arrière de la cellule, une grille principale (11) étant une électrode segmentée, et un point de soudure étant disposé sur une extrémité de la grille principale (11) ; imprimer une colle thermofusible en bande (13) à la position du point de soudure dans une direction perpendiculaire à la grille principale (11), le point de soudure sortant de la colle thermofusible ; découper la cellule, le long d'une région de découpe de cellule (12), en une pluralité de cellules plus petites ; revêtir la position du point de soudure de la grille principale (11) sur la surface avant de chacune des cellules plus petites avec un adhésif conducteur ou une pâte à braser (14) ; superposer le point de soudure de la grille principale (11) sur la surface arrière de l'une des cellules plus petites sur celle de la grille principale (11) sur la surface avant d'une autre des cellules plus petites, puis les chauffer, de sorte que les deux cellules plus petites sont électriquement connectées au moyen de l'adhésif conducteur ou de la pâte à braser (14) ; et connecter de façon séquentielle la pluralité de cellules plus petites pour former la chaîne de cellules solaires. Le procédé augmente la zone d'utilisation des cellules dans une région active de l'ensemble et augmente la puissance de l'ensemble.
