Solar cell and solar module

The utility model provides a solar cell and a solar module. The solar cell includes a silicon chip body, at least four main grid lines, and a plurality of auxiliary grid lines. The at least four main grid lines extend on the light receiving surface of the silicon chip body in the vertical direction and are spaced apart in the horizontal direction, the plurality of auxiliary grid lines extend on the light receiving surface of the silicon chip body in the horizontal direction and are spaced apart in the vertical direction. The main grid lines are linear lines, the auxiliary grid lines are non-linear lines, the main grid lines and the auxiliary grid lines are intersected, the auxiliary grid lines at the two side of each main grid line are symmetrically arranged. According to the utility model, the auxiliary grid lines are non-linear lines, electronic transmission distance can be reduced as much as possible under the condition of guaranteeing the shielding area, and therefore, the losses of photoelectric current are reduced, and the conversion efficiency of the cell is improved.
