Solar cell module

A solar cell module comprising:

• a solar cell including a first main surface and a second main surface opposite to the first main surface;
• a first wiring member connected to the first main surface of the solar cell;
• and
• a second wiring member connected to the second main surface of the solar cell, wherein
• the solar cell comprises:
• a first electrode provided on the first main surface side of the solar cell and connected to the first wiring member, wherein the first electrode includes a plurality of first finger electrodes parallel to each other;
• and
• a plurality of second finger electrodes provided on the second main surface side of the solar cell and connected to the second wiring member, wherein the plurality of second finger electrodes are parallel to each other and face regions where the plurality of first finger electrodes are present, and the plurality of second finger electrodes are separated from each other in an area overlapping with the second wiring member, and
• each of the plurality of second finger electrodes includes a linear section and an auxiliary electrode section, wherein the auxiliary electrode section is provided in a region where the second wiring member is connected, a width of the auxiliary electrode section is greater than a width of the linear section, and the auxiliary electrode section comprises a same material as that of the linear section.

A solar cell module comprising:

• a solar cell including a light receiving surface and a rear surface opposite to the light receiving surface;
• a first wiring member connected to the light receiving surface of the solar cell;
• and
• a second wiring member connected to the rear surface of the solar cell, wherein
• the solar cell comprises:
• a first electrode provided on the light receiving surface side of the solar cell and connected to the first wiring member, wherein the first electrode includes a plurality of first finger electrodes parallel to each other;
• and
• a second electrode provided on the rear surface side of the solar cell and connected to the second wiring member, wherein
• the second electrode includes:
• a plurality of second finger electrodes parallel to each other and facing regions where the plurality of first finger electrodes are present;
