Abstract
(EN)
Provided is a solar cell module that enables the modularization of various three-terminal type tandem solar cells. A solar cell module 100 comprises cell groups 3 each containing solar cells 1, and each solar cell 1 includes photoelectric conversion parts B, T, first and second terminals b, e for the photoelectric conversion part B, and first and third terminals b, f for the photoelectric conversion part T. N number of the photoelectric conversion parts B of the cell group 3 are connected in series. When the first terminal b on one end side of a first cell group 3 is configured to have a reference potential, the second terminal e on the other end side of the mth cell group 3 is connected to the first terminal b on one end side of another cell group 3, and N number of the third terminals f of the mth cell group 3 are respectively connected to N number of the first terminals b of an m+1th cell group 3. The difference in potential between the second terminal e on the other end side of the mth cell group 3 and the first terminal b on one end side of the other cell group 3, such terminals being connected together, is 10% or less of the difference in potential between the second terminal e and the first terminal b of the mth cell group 3.

L'invention concerne un module de cellules solaires qui permet la modularisation de diverses cellules solaires en tandem de type à trois bornes. Un module de cellules solaires 100 comprend des groupes de cellules 3 contenant chacun des cellules solaires 1, et chaque cellule solaire 1 comprend des parties de conversion photoélectrique B, T, des première et deuxième bornes b, e pour la partie de conversion photoélectrique B, et des première et troisième bornes b, f pour la partie de conversion photoélectrique T. Un nombre N des parties de conversion photoélectrique B du groupe de cellules 3 sont connectées en série. Lorsque la première borne b sur un côté d'extrémité d'un premier groupe de cellules 3 est configurée pour avoir un potentiel de référence, la deuxième borne e sur l'autre côté d'extrémité du mth groupe de cellules 3 est connectée à la première borne b sur un côté d'extrémité d'un autre groupe de cellules 3, et le nombre N des troisièmes bornes f du mth groupe de cellules 3 sont respectivement connectées au nombre N des premières bornes b d'un m+1th groupe de cellules 3. La différence de potentiel entre la deuxième borne e sur l'autre côté d'extrémité du mth groupe de cellules 3 et la première borne b sur un côté d'extrémité de l'autre groupe de cellules 3, ces bornes étant connectées ensemble, représente 10 % ou moins de la différence de potentiel entre la deuxième borne e et la première borne b du mth groupe de cellules 3.
