SOLAR MODULE AND MANUFACTURING METHOD THEREFOR

摘要

Provided is a solar module having improved photoelectric conversion efficiency and a method for producing this solar module. The wiring (32) has a first linear portion (32a) and a second linear portion (32b). The first linear portion (32a) is arranged at least partially on a finger portion (21a) of a first electrode (21). The first linear portion (32a) is connected electrically to the finger portion (21a) of the first electrode (21). The second linear portion (32b) is arranged at least partially on a finger portion (22a) of a second electrode (22). The second linear portion (32b) is connected electrically to the finger portion (22a) of the second electrode (22). Either the first linear portion (32a) or the second linear portion (32b) is narrower than the other.

主权项

1. A solar module comprising:
a plurality of solar cells each having a photoelectric conversion unit and a first electrode and a second electrode arranged on one main surface of the photoelectric conversion unit; a wiring member electrically connecting the first electrode of one adjacent solar cell to the second electrode of the other adjacent solar cell; and an adhesive layer bonding the wiring member and either the one adjacent solar cell or the other adjacent solar cell; the wiring member having an insulating substrate and wiring provided on the insulating substrate; the first electrode and the second electrode each having a plurality of finger portions; the wiring having a first linear portion arranged at least partially on a finger portion of the first electrode and connected electrically to the finger portion of the first electrode, and a second linear portion arranged at least partially on a finger portion of the second electrode and connected electrically to the finger portion of the second electrode; and one of the first linear portion and the second linear portion having a narrower width than the other.
