Solar cell and photovoltaic module

A photovoltaic module, comprising:

• at least one cell string including a plurality of solar cells, wherein the plurality of solar cells are electrically connected in sequence;
• at least one encapsulation layer configured to cover a surface of the at least one cell string;
• and
• at least one cover plate configured to cover a surface of the at least one encapsulation layer facing away from the at least one cell string;
• wherein each of the plurality of solar cells includes:
• a substrate;
• a tunneling dielectric layer formed on the substrate;
• a doped conductive layer formed on the tunneling dielectric layer, wherein the doped conductive layer has a plurality of protrusions arranged along a first direction, and each protrusion of the plurality of protrusions extends along a second direction perpendicular to the first direction;
• at least one conductive connection structure formed between two adjacent protrusions and connected with sidewalls of the two adjacent protrusions;
• a passivation layer over the doped conductive layer and the at least one conductive connection structure;
• and
• a plurality of finger electrodes, wherein 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.
