Claim 0:
1. A solar cell, comprising:
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, wherein the plurality of first electrodes respectively correspond to the plurality of doped conductive layers and are arranged at intervals along a second direction perpendicular to the first direction, and each of the plurality of first electrodes is disposed on and electrically connected to a corresponding one of the plurality of doped conductive layers;
a plurality of conductive transport layers arranged in a plurality of columns of conductive transport layers disposed at intervals along the first direction, each respective column of conductive transport layers including a respective set of conductive transport layers disposed at intervals along the second direction, wherein at least one conductive transport layer is located between every two adjacent doped conductive layers in the plurality of doped conductive layers, and in contact with a side surface of each of the two adjacent doped conductive layers, wherein conductive transport layers in adjacent columns of conductive transport layers are arranged in a staggered manner along the first direction.
