Abstract

Provided are a solar cell and a photovoltaic module. The solar cell includes a substrate, a passivation contact structure, a passivation layer, and at least one first electrode. The substrate has a first side and a second side opposite to the first side, where the first side includes metallization pattern regions and non-metallization pattern regions disposed alternatingly along a first direction, and the second side has a greater roughness than the metallization pattern regions. The passivation contact structure covers the metallization pattern regions and includes a first tunneling dielectric layer and a first doped conductive layer. The passivation layer is formed over the non-metallization pattern regions and the first doped conductive layer. A respective first electrode includes a respective connecting electrode over a respective metallization pattern region and a plurality of spot electrodes disposed at intervals along a second direction. The plurality of spot electrodes are disposed below the respective connecting electrode and connected to the respective connecting electrode, the plurality of spot electrodes penetrate the passivation layer to be in electrical contact with the first doped conductive layer, and the respective connecting electrode includes at least one material that is different from a material included in the plurality of spot electrodes.
