Photovoltaic cell and photovoltaic module

Abstract

The application belongs to the technical field of solar cells, and particularly relates to a photovoltaic cell and a photovoltaic module. The surface of the photovoltaic cell is provided with a plurality of grid lines arranged at intervals, and the grid lines are provided with solder pads. The solder pad comprises a body, the body is provided with a hollow area, the hollow area is provided with a connecting part, the solder pad further comprises a supporting part arranged on one side of the connecting part, and the connecting part is electrically connected with the grid line. The connecting part is used for connecting with a first conductive wire, and the supporting part is used for positioning the first conductive wire. Through the above design, the offset of the first conductive wire during soldering with the solder pad can be avoided, and the offset during lamination can also be avoided. In addition, the body of the solder pad is provided with a hollow area, so that the area of the solid part of the body is reduced. When the body of the solder pad is prepared, the coating area of the metal paste can be reduced, and the metallization cost is reduced.
