Abstract

The solar cell includes: a substrate; a tunneling dielectric layer located on the first surface of the substrate; multiple doped conductive layers, where the multiple doped conductive layers are located on a surface of the tunneling dielectric layer away from the substrate, and are disposed at intervals; multiple first electrodes, where the multiple first electrodes are disposed at intervals, extend along a first direction, are arranged on a side of the multiple doped conductive layers away from the substrate, and are electrically connected to the multiple doped conductive layers; at least one conductive transport layer, where the at least one conductive transport layer is located between every two adjacent doped conductive layers in the multiple doped conductive layers, and is in contact with a side surface of the multiple doped conductive layers.
