Abstract

Embodiments of the present disclosure 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, 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.
