Abstract: A solar cell includes: a first surface, a second surface, a first side surface and a second side surface; wherein first electrode strips are provided on the first surface, and second electrode strips are provided on the second surface; the first electrode strips include first discontinuous electrodes, each including at least two first electrode segments, and the second electrode strips include second discontinuous electrodes, each including at least two second electrode segments; and the first electrode segments include a first end electrode segment adjacent to the first side surface, the second electrode segments include a second end electrode segment adjacent to the first side surface, and a length of the first end electrode segment is different from a length of the second end electrode segment.

Abstract: A solar cell includes a light facing face provided with a plurality of front electrodes, and a shadow face provided with a plurality of back electrodes; the plurality of front electrodes are arranged separately in a length direction to form a front-electrode strip; the plurality of back electrodes are arranged separately in the length direction to form a back-electrode strip; a center line of the front-electrode strip in the length direction is a first center line; a center line of the back-electrode strip in the length direction is a second center line; a projection of the first center line in a first direction and a projection of the second center line in the first direction coincide; and a projection of a starting point of the front-electrode strip in the first direction and a projection of a starting point of the back-electrode strip in the first direction coincide.
