Abstract
A solar cell including: a semiconductor substrate having a first surface and a second surface opposite to each other, and a plurality of side surfaces adjacently connected between the first and the second surfaces; a passivated contact structure, located on a part of the first surface, including an interface passivation layer and a first doped semiconductor layer that are sequentially stacked. In a direction from the first surface to the second surface, respective side surface of the plurality of side surfaces includes a first region and a second region that are sequentially adjacent. The first region protrudes in a direction away from the respective side surface relative to the second region. The first doped semiconductor layer is located on a surface of the first region. The first doped semiconductor layer located in the first region and the first doped semiconductor layer located on the first surface are integrally continuous.
