Solar cell and photovoltaic module

A photovoltaic module, comprising a solar cell, wherein the solar cell comprises:

• a semiconductor substrate, wherein the semiconductor substrate comprises:
• a first surface and a second surface that are opposite to each other, and
• a plurality of side surfaces connected between the first surface and the second surface;
• and
• a passivated contact structure located on at least a portion of the first surface, wherein the passivated contact structure comprises an interface passivation layer and a first doped semiconductor layer that are stacked sequentially, and a first portion of the first doped semiconductor layer is located on the portion of the first surface:
• wherein a side surface of the plurality of side surfaces comprises a first region and a second region that are arranged along a first direction from the first surface to the second surface, the first region protrudes in a second direction away from the side surface relative to the second region,
• wherein a second portion of the first doped semiconductor layer is located on a first portion of a surface of the first region, the second portion of the first doped semiconductor layer is integrally continuous with the first portion of the first doped semiconductor layer,
• wherein a second portion of the surface of the first region adjacent to the second region is uncovered by the first doped semiconductor layer, and
• wherein a distance between the second portion of the first doped semiconductor layer and the second region along the first direction is greater than or equal to 1 μm.
