Abstract

The present application provides a solar cell and a photovoltaic module, and belongs to the technical field of solar cells. The solar cell includes a semiconductor substrate, where the semiconductor substrate has a first surface and a second surface that are opposite to each other and a plurality of side surfaces adjacently connected between the first surface and the second surface; and a passivated contact structure, at least located on a part of the first surface of the semiconductor substrate. The passivated contact structure includes 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 further located on a surface of the first region. A part of the first doped semiconductor layer located in the first region and another part of the first doped semiconductor layer located on the first surface are integrally continuous.
