The disclosure is applicable to the technical field of solar cells and provides a solar cell. In the solar cell, a P-type silicon substrate is used as a base layer, a first surface of the P-type silicon substrate is not completely covered with P-type doped layers, and a second surface of the P-type silicon substrate is not completely covered with N-type doped layers. Moreover, on the P-type silicon substrate, the P-type doped layers are locally arranged on a light-facing surface. In addition, the Ntype doped layers are locally arranged on a light-sheltered surface, and a total area of all third regions is set to be greater than that of all first regions
