NOVELTY - The utility model claims a dye-sensitized solar cell. dye-sensitized solar battery of the utility model comprises a combined counter electrode, a working electrode and an electrolyte, wherein the composite electrode includes a platinum layer and a porous graphene layer on the platinum layer. Because the porous graphene layer has many holes, so it can increase the electron transfer, to improve the conversion efficiency of the dye-sensitized solar cell.
