| Research Abstract |
Ionic liquids have been regarded as promising electrolytes for dye-sensitized solar cells. In this work, new class of ionic liquids based on quaternary phosphonium cations containing phenyl group(s) was synthesized, physicochemically and electrochemically characterized in order to evaluate the possibility of the ionic liquids as dye-sensitized solar cell electrolytes. It was found that the ionic liquids showed favorable transport property and high thermal and electrochemical stabilities, which might be attributed to the interactions associated with aromatic rings in the phosphonium cations.
