Abstract

See full text

A solar cell and a photovoltaic module are disclosed, including: a substrate; a tunneling dielectric layer and a doped conductive layer disposed on the substrate, the tunneling dielectric layer being disposed between the doped conductive layer and a surface of the substrate, the doped conductive layer having a N-type or P-type doping element and having a plurality of first heavily doped regions spaced apart from each other and extending in a first direction, a doping concentration in the first heavily doped regions being greater than that in other regions of the doped conductive layer; a passivation layer disposed on a surface of the doped conductive layer facing away from the substrate; and a plurality of electrodes spaced apart from each other, extending in a second direction and penetrating the passivation layer to contact the doped conductive layer, at least two first heavily doped regions contacting a same electrode.
