Abstract: OF THE DISCLOSURE 
Embodiments of the present disclosure relate to the photovoltaic field, and provide a solar 
cell and a photovoltaic module. The solar cell includes a substrate, a tunneling dielectric layer 
formed on the substrate, a doped conductive layer formed on the tunneling dielectric layer, at 
least one conductive connection structure, a passivation layer over the doped conductive layer 
and the at least one conductive connection structure, and a plurality of finger electrodes. The 
doped conductive layer has a plurality of protrusions arranged along a first direction, and each 
protrusion extends along a second direction perpendicular to the first direction. The at least one 
conductive connection structure is formed between two adjacent protrusions and connected 
with sidewalls of the two adjacent protrusions. Each finger electrode of the plurality of finger 
electrodes extends along the second direction to penetrate the passivation layer and connect to 
a respective protrusion. Embodiments of the present disclosure can at least improve 
performance of solar cells.
