Carbon black was embedded in mixtures of poly(ethylene oxide) and poly(vinylidene fluoride-hexafluoropropylene) to make a carbon/polymer composite slurry, which was deposited onto a transparent conducting glass substrate by a doctor-blade coating for application in dye-sensitized solar cells (DSSCs) as a counter-electrode (CE) material. The experiments indicated that the photovoltaic parameters of the DSSCs were strongly dependent on the carbon concentration in the slurry. The device with a carbon CE whose mass ratio was 1 : 1 (mass ratio carbon black mass to polymer mass) exhibited an overall energy conversion efficiency of 4.62%; this was comparable to that of a device with platinum as a CE (5.32%) under the same test conditions. The better electrocatalytic activity of CE-1.0 (where 1.0 indicates the mass ratio of carbon black to polymer) for the reduction of triiodide resulted a higher performance of the DSSC with such a CE.
