Electrochemical stability on 1-ethyl-3-methylimidazolium bis (trifluoromethyl sulfonyl) imide ionic liquid for dye sensitized solar cell application

The usage of ionic liquids has recently became a promosing alternative for replacement of conventional volatile organic-based electrolyte for Dye Sensitized Solar Cells (DSSCs) due to its electrochemical stability, high conductivity and low vapor pressure. However, degradation of ionic liquid concen...

By using electro-oxidation method, this research aimed to evaluate the degradation of 1-Ethyl-3-Methylimidazolium bis (trifluoromethyl sulfonyl) imide EMIMN(Tf)2 ionic liquid by analyzing the change of concentration with respect to high voltage differences (i.e., 1 V, 2 V, 4 V, 6 V, 8 V and 10 V).
