1. A solar cell comprising:
a plurality of first pad groups and a second pad group,
wherein the plurality of first pad groups and the second pad group are distributed along a first direction on a back surface of the solar cell, the second pad group is located in a region adjacent to a cut edge or a non-cut edge of the solar cell, and the plurality of first pad groups are distributed in a region away from the cut edge or the non-cut edge of the solar cell,
wherein a distance, along the first direction, between a pad in the second pad group and a pad in the plurality of first pad groups adjacent to the pad in the second pad group is greater than a distance, along the first direction, between adjacent pads in adjacent first pad groups of the plurality of first pad groups,
wherein the second pad group comprises two second pad groups distributed in the region of the solar cell adjacent to the cut edge, the two second pad groups are a third pad group and a fourth pad group respectively, and the fourth pad group is closer to the cut edge than the third pad group, and
wherein a distance between a pad in the third pad group and a pad in the first pad groups adjacent to the pad in the third pad group is equal to the distance between adjacent pads in adjacent first pad groups, and a distance between a pad in the fourth pad group and a pad in the first pad groups adjacent to the pad in the fourth pad group is greater than the distance between adjacent pads in adjacent first pad groups.
