“…The stability constants of the mono complex CtCl 2 I 2 (β 1 = 2.39•10 3 ) and bis complex Ct(ClI 2 ) 2 (β 2 = 1.20•10 7 ) were calculated by the linear least squares method using the equation , (4) which describes the simultaneous coordination of two iodine molecules by an organic halide molecule. The stability of p xylylenebis(tetrahydrothiophenium) bis(triiodide) was estimated by stoichiometric dilution in a chloroform solution containing 5% acetonitrile.…”

“…The mixing ratio of DMSO and ionic liquid was taken to be the one providing the highest conductivity in is not similar to our results that the short current density is suppressed as the electric conductivity becomes higher. Some other researcher also reported a positive correlation between the short current density and electric conductivity [16] [17].…”

Fluorinated oligomer gel is suitable to the electrolyte of dye sensitized solar cell. This article studied mainly in the scope of electric conductivity, including ionic liquid in the electrolyte. It was found that the ratio of mixing with dimetyl sulfoxide and the concentration of LiI affect the conductivity. The behavior is different depending on the type of ionic liquid. Although the mixing ionic liquid enhances the conductivity, the short circuit current density of assembled solar cell with it was suppressed so much.

“…Many other ionic liquids, including ammonium [145], guanidinium [146,147], phosphonium [148,149], pyridinium, and sulfonium [150,151,152], have also been investigated for their potential use as solvent-free electrolytes in dye-sensitized solar cells. Nonetheless, these have not yielded good efficiencies, owing to their high viscosity as well as mass-transport problems [148,149,150,151,152].…”

Dye-sensitized solar cells (DSSCs) have been intensely researched for more than two decades. Electrolyte formulations are one of the bottlenecks to their successful commercialization, since these result in trade-offs between the photovoltaic performance and long-term performance stability. The corrosive nature of the redox shuttles in the electrolytes is an additional limitation for industrial-scale production of DSSCs, especially with low cost metallic electrodes. Numerous electrolyte formulations have been developed and tested in various DSSC configurations to address the aforementioned challenges. Here, we comprehensively review the progress on the development and application of electrolytes for DSSCs. We particularly focus on the improvements that have been made in different types of electrolytes, which result in enhanced photovoltaic performance and long-term device stability of DSSCs. Several recently introduced electrolyte materials are reviewed, and the role of electrolytes in different DSSC device designs is critically assessed. To sum up, we provide an overview of recent trends in research on electrolytes for DSSCs and highlight the advantages and limitations of recently reported novel electrolyte compositions for producing low-cost and industrially scalable solar cell technology.
