Synthesis of a novel alkylimidazolium iodide containing an amide group for electrolyte of dye-sensitized solar cells

Effects of the Alkyl Chain Length of Imidazolium Iodide in the Electrolyte Solution on the Performance of Black-Dye-Based Dye-Sensitized Solar Cells

“…The viscosity of imidazolium iodide is reported toincrease with increasing the alkyl chain length at the same temperature because Van der Waals forces between the alkyl chains induce the aggregation of imidazolium iodides [28][29][30][31][32][33]. Since the viscosity of the electrolyte solution of the DSC is one of the quite important parameters to obtain a higher conversion efficiency, internal resistances of the DSCs with five kinds of electrolyte solutions prepared in this study have been investigated by the electrochemical impedance spectroscopic (EIS) measurements.…”

Ionic conductivity improvement in poly (propylene) carbonate-based gel polymer electrolytes using 1-butyl-3-methylimidazolium iodide (BmimI) ionic liquid for dye-sensitized solar cell application

“…The main advantages of ionic liquids over organic solvents are low vapor pressure, high ionic conductivity, good chemical and thermal stability, non-flammability, as well as wide electrochemical stability window [6][7][8]. The imidazolium iodide-based ionic liquids are widely used in DSSC as it may play the roles of both conductive medium and nonvolatile plasticizers in electrolytes as well as provide better performance in dye-sensitized solar cells [9,10].…”

Effect of 1‐butyl‐3‐methylimidazolium iodide containing electrospun poly(vinylidene fluoride‐co‐hexafluoropropylene) membrane electrolyte on the photovoltaic performance of dye‐sensitized solar cells

“…To improve the photovoltaic efficiency of DSSCs, 1-butyl-3-methylimidazolium iodide (BMImI) has been evaluated as polymer electrolyte additive to enhance the physical diffusion of I 2 and I 2 3 ions. 7,8 Polymer electrolytes can be prepared by a number of processing techniques including drawing, template synthesis, casting, phase separation, and electrospinning. [9][10][11][12][13][14] Among these, electrospinning is a simple and cost-effective technique for producing electrospun polymer membranes that affords an average fiber diameter in the submicron range with high porosity, large surface area, and a fully interconnected pore structure with good mechanical strength.…”

“…Although polymer gel electrolyte‐based DSSCs do not suffer from electrolyte loss, they tend to have low power conversion efficiencies attributed to the lower ionic mobility of ions. To improve the photovoltaic efficiency of DSSCs, 1‐butyl‐3‐methylimidazolium iodide (BMImI) has been evaluated as polymer electrolyte additive to enhance the physical diffusion of and ions . Polymer electrolytes can be prepared by a number of processing techniques including drawing, template synthesis, casting, phase separation, and electrospinning .…”
