Abstract
(EN)
A solar cell (100) includes: a first conductivity-type layer (21) and a second conductivity-type layer (22) each provided on a rear surface of a semiconductor substrate (10); first electrodes (41) provided on the first conductivity-type layer; and second electrodes (42) provided on the second conductivity-type layer. The first electrodes and the second electrodes are spaced apart from each other, and the first electrodes include a plurality of regions isolated from one another by the second electrodes disposed therebetween. Each of the plurality of regions of the first electrodes includes a non-mounting electrode section (410) and a wiring-mounting electrode section (411) having a larger electrode height than the non-connection electrode section. In two adjacent first electrode regions, an imaginary line connecting the top of the wiring-mounting electrode section of one of the regions and the top of the wiring-mounting electrode section of the other region does not cross the second electrode disposed between the two regions.

L'invention concerne une batterie solaire (100) qui est pourvue : d'une couche d'un premier type de conductivité (21) et d'une couche d'un second type de conductivité (22) qui sont disposés sur une surface arrière d'un substrat semi-conducteur (10) ; de premières électrodes (41) disposées sur la couche du premier type de conductivité ; et de secondes électrodes (42) disposées sur la couche du second type de conductivité. Les premières électrodes et les secondes électrodes sont espacées l'une de l'autre, et les premières électrodes comprennent une pluralité de régions séparées par les secondes électrodes disposées entre les premières électrodes. La pluralité de régions des premières électrodes comprennent chacune une partie d'électrode non de connexion (410) et une partie d'électrode de connexion de câblage (411) ayant une plus grande hauteur d'électrode que la partie d'électrode de non connexion. Dans deux régions de première électrode adjacentes, une ligne imaginaire reliant le sommet de la partie d'électrode de connexion de câblage de l'une des régions et le sommet de la partie d'électrode de connexion de câblage de l'autre région ne coupe pas la seconde électrode disposée entre les deux régions.
