![]() The highest efficiency of DSSCs is 6.85 % for 1-(3-hexenyl)-3-methyl imidazolium iodide and 5.93 % for 1-(3-butenyl)-3-methyl imidazolium iodide electrolyte, which is much higher than that of 5.17 % with the counterpart 1-hexyl-3-methyl imidazolium iodide electrolyte.ĭye-sensitized solar cell electrolyte ionic liquid viscosity. To read the full-text of this research, you can request a copy directly from. The cation also affects the viscosity of ionic liquids. LowViscosity Paramagnetic Ionic Liquids with Doubly Charged Co(NCS)42 Ions. This enhancement is detected by fabricating dye-sensitized solar cells (DSSCs) with electrolytes containing the two ILs and I 2. viscosity of fluids as being limited by the availability of holes. The low viscosity of the synthesized ionic liquids would enhance the diffusion of redox couples. It was found that the viscosity was sensitive to temperature and decreased dramatically when temperature is high. The viscosity of ionic liquids was measured over temperature range of 298 K to 348 K. The molecular dynamics simulation shows that the double bond introduced in the alkane chain greatly changes the molecular system space arrangement and diminishes the packing efficiency, leading to low viscosity. The four ionic liquids all showed good thermal stability with decomposition temperature higher than 600 K. ![]() Ionic liquid according to claim 1, characterised in that the chloride content of the ionic liquid is less than 1 00 ppm. These new ionic liquids exhibit high thermal stability and low viscosity (104 cP and 80 cP, respectively). Amino acid ionic liquids, composed of tetrabutylphosphonium (P4444) cation and both asparagic acid (Asp) and lysine (Lys) anions, are polar and of low. Ionic liquid comprising cations and anions, characterised in that the viscosity is 10 to 100 mm 2 /s and the electrochemical stability to reduction and oxidation is greater than 4.5 V. ILs are liquids showing high ion density. Two types of ionic liquids (ILs), 1-(3-hexenyl)-3-methyl imidazolium iodide and 1-(3-butenyl)-3-methyl imidazolium iodide, are synthesized by introducing an unsaturated bond into the side alkyl chain of the imidazolium cation. The main disadvantages are high density, high viscosity, and low conductivity.
