Solar cell and photovoltaic module

Abstract

The solar cell includes: a substrate; a tunneling dielectric layer disposed over a first surface of the substrate; a plurality of doped conductive layers arranged at intervals over the tunneling dielectric layer; a plurality of first electrodes each extending in a first direction, where the plurality of first electrodes are arranged at intervals along a second direction, and each first electrode is disposed on and electrically connected to a corresponding one of the plurality of doped conductive layers; and at least one conductive transport layer, where the at least one conductive transport layer includes a respective conductive transport layer between every two adjacent doped conductive layers and in contact with a side surface of each of the two adjacent doped conductive layers. The at least one conductive transport layer and the plurality of doped conductive layers are doped with doping ions of a same type.
