Dye-sensitized solar cells (DSSCs) were discovered by O'Reagan and Grätzel in 1991. Lots of research has been done since then, trying to improve the cell efficiency in generating electrical power from sunlight. The most efficient DSSCs used today are based on ruthenium(II) bipyridyle complexes as sensitizers, combined with an electrolyte consisting of iodide/triiodide redox couple in an organic solvent. Volatility of the organic solvents limits industrial application of DSSCs, and relatively high price for ruthenium metal make it expensive to produce DSSCs using these materials on an industrial scale. Therefore, the less expensive organic dyes and non-volatile solvents like ionic liquids (ILs) are favorable to use. In this work, we present a study of two organic dyes (D9L6 and TH208 shown in Figure 1, left and right, respectively) and their behavior with deferent electrolytes in DSSCs.
