Abstract

The present disclosure provides a solar cell, a solar cell string, and a photovoltaic module. The solar cell includes a cell substrate, a solder strip arranged on the cell substrate, and a reinforced limiting adhesive dot and an additional limiting adhesive dot that are attached to the solder strip and the cell substrate. The cell substrate includes an adhesion-enhanced region immediately adjacent to at least one edge of the cell substrate, and an additional region arranged at a side of the adhesion-enhanced region away from the at least one edge. The additional limiting adhesive dot is arranged in the additional region. The reinforced limiting adhesive dot is arranged in the adhesion-enhanced region. An adhesion force between the reinforced limiting adhesive dot and the solder strip is greater than that between the additional limiting adhesive dot and the solder strip.
