A polymeric ionic liquid issued from an ionic liquid monomer composed of a methacrylate polymerizable group, a polar tri(ethylene oxide) spacer, a trifluoromethane sulfonic anion and a free imidazolium cation was employed as a solid electrolyte for dye-sensitized solar cells. The simple device configuration based on dip-coated nanoporous TiO 2 electrode sensitized by N3 ruthenium-based dye gave the conversion efficiency of up to 1.74% under AM 1.5 simulated solar light illumination. Effect of TiO 2 porous film thickness on overall energy conversion efficiency was discussed. It has been found that the most appropriate thickness for the polymeric ionic liquid based electrolyte dye sensitized solar cell is around 7 µm.
