Claim 0:
1. A solar cell, comprising:
a front electrode on a side of an illuminated surface;
a back electrode;
a functional layer disposed between the front electrode and the back electrode;
wherein the front electrode and the back electrode are disposed opposite to each other;
wherein the front electrode comprises a high-conductivity region and a low-conductivity region that are adjacent to each other, and the back electrode comprises a high-conductivity region and a low-conductivity region that are adjacent to each other;
wherein the low-conductivity region of the front electrode comprises a transparent conductive oxide layer and a first conductive mesh layer embedded in the transparent conductive oxide layer;
wherein the first conductive mesh layer is electrically connected to the functional layer;
wherein the high-conductivity region of the front electrode comprises the transparent conductive oxide layer and a second conductive mesh layer embedded in the transparent conductive oxide layer;
wherein the second conductive mesh layer is electrically connected to the functional layer; and
wherein a side length of the second conductive mesh layer in the high-conductivity region of the front electrode is less than a side length of the first conductive mesh laver in low high-conductivity region of the front electrode.
