Abstract
The solar cell includes a substrate, a tunneling layer disposed on a first surface, and a first doped conductive layer disposed on a surface of the tunneling layer. The solar cell further includes a second doped conductive layer disposed on a surface of the first doped conductive layer, where the second doped conductive layer includes: multiple first portions and multiple second portions arranged alternately in a direction perpendicular to a predetermined direction and perpendicular to a thickness direction of the second doped conductive layer, each of the multiple first portions and the multiple second portions extends along the predetermined direction, a doping element concentration of the first doped conductive layer is lower than a doping element concentration of each of the multiple first portions, and the doping element concentration of each of the multiple first portions is lower than a doping element concentration of each of the multiple second portions.
