Abstract
The embodiment of the present application provides a solar cell and a photovoltaic system. The solar cell comprises a cell substrate, the cell substrate comprises a substrate, a boron-doped layer and a phosphorus-doped layer, the boron-doped layer and the phosphorus-doped layer are located on opposite sides of the substrate; the boron-doped layer and the phosphorus-doped layer away from the substrate are provided with conductive layers; a metal foil layer is located on the side of the conductive layer away from the substrate, and conductive glue is arranged between the conductive layer and the metal foil layer; wherein the metal foil layer has a grid structure. The solar cell has higher double-side rate and photoelectric performance.
