Binary room-temperature ionic liquids based electrolytes solidified with Si02 nanoparticles for dye-sensitized solar cells

In this study, binary ionic liquids (bi-IL) of imidazolium salts containing cations with different carbon side chain lengths (C = 2, 4, 6, 8) and anions such as iodide (I − ), tetrafluoroborate (BF4 − ), hexafluorophosphate (PF6 − ) and trifluoromethansulfonate (SO3CF3 − ) were used as electrolytes in dye-sensitized solar cells
