Abstract

The effects of 1,3-alkylimidazolium iodide derivatives in the electrolytic solution of dye-sensitized solar cell were investigated. The combination of lithium iodide and 1-ethyl-3-methylimdazolium iodide was revealed to exhibit higher effciency (8.6%) than 1-methyl-3-propylimidazolium iodide or 1-butyl-3-methylimidazolium iodide. The influence of guanidine thiocyanate was examined for the electrolyte of 1-ethyl-3-methylimidazolium iodide.
