Metal grids covered by graphene were used as transparent conductive electrodes in dye sensitized solar cells. The efficiency of dye sensitized solar cells with graphene-on-Pt grids was 0.4%. Compared to the control group, in which the platinum grids were used as a transparent conductive layer, the efficiency of dye sensitized solar cells with graphene was more than 2 times better. To our knowledge, it is the most efficient dye sensitized solar cell to use a graphene-based transparent conductive electrode without a conductive oxide support such as fluorine-doped tin oxide or indium-doped tin oxide. The dye sensitized solar cell prepared by 150 °C as the low temperature processes, which are essential for fabricating flexible dye sensitized solar cells, was fabricated using a hybrid graphene on Ni grids transparent conductive electrode, and it exhibited an efficiency of 0.25%. The mechanical properties of the flexible hybrid transparent electrode are better than the oxide-based transparent conductive electrode in both bending and stretching tests. Therefore, the long-term stability of the flexible dye sensitized solar cells could be enhanced by using this new transparent conductive layer.
