“…When the cells were rst assembled, the absolute efficiency of the liquid reference cell exceeded that of CNC40 by 0.27%. These results, as well as an assessment of previous studies, 7,[13][14][15]31 emphasize the detrimental effects of solvent evaporation and leakage occurring in liquid electrolyte DSSCs. The samples having no PEO at all (i.e.…”

“…Due to evaporation or leakage, the volume of electrolyte in the device may reduce over time, ultimately resulting in a drop of the cell performance. 7,[13][14][15] This problem can, in part, be addressed by using organic solvents of low volatility (e.g. 3-methoxypropionitrile in place of MeCN), and there is also active interest in replacing the organic solvent by water.…”

The study presented describes the preparation of solvent-free nano composite gel electrolytes in combination with copper(I)-based dye-sensitized solar cells (DSSCs). The electrolytes comprise poly(ethylene oxide) (PEO) and cellulose nano crystals (CNCs) and an I 3 À /I À redox shuttle. The quasisolid-state DSSCs show increased photoconversion performance with increased amount of CNC in the electrolyte. DSSC performances measured on the day that the devices are fabricated show that when the electrolyte is composed of 80% CNC, a cell efficiency of 1.09% is reached compared to 1.16% using a standard liquid I 3 À /I À electrolyte. DSSCs containing the nano composites and the copper(I)-based dye show robust stability over time, and after 60 days, DSSCs with the PEO/CNC/I 3 À /I À electrolyte outperform those containing the liquid electrolyte.

“…The plastic crystal has a body-centered cubic structure with two SN molecules per unit cell, in which the central C–C bonds orient along the diagonals of the cube and N atoms are at the center of the faces. This structure allows a high molecular diffusivity through trans-gauche isomerization and molecular jump from one diagonal of the cube to another. − Since the invention of this first succinonitrile-based electrolyte, numerous SN–XI–I 2 systems have been investigated, where X represents an IL cation. − A large size of cation, acting as a plasticizer, introduced amorphicity in the plastic crystal phase of the SN, which resulted in increased electrical conductivity of the electrolyte and thereby cell efficiency of the DSSC . Instead of an IL, an organic salt such as tetrabutylammonium iodide or tetraethylammonium iodide has also been used with SN and I 2 , in which the tetrabutylammonium iodide exhibited better electrolytic and photovoltaic properties. ,, …”

Understanding the Electrical Transport–Structure Relationship and Photovoltaic Properties of a [Succinonitrile–Ionic Liquid]–LiI–I₂ Redox Electrolyte

The properties of succinonitrile-based electrolytes can be enhanced by the addition of an ionic liquid (IL). Here, we have reported the relationship between the electrical transport properties and the structure of a new [(1 – x)succinonitrile:xIL]–LiI–I2 electrolyte, where the mole fraction (x) of the IL (1-butyl-3-methyl imidazolium iodide) was varied from 0 to 40%. Compositional variation revealed the optimum conducting electrolyte (OCE) at x = 10 mol %, possessing an electrical conductivity (σ25°C) of ∼7.5 mS cm–1 with an enhancement of ∼369%. The partial replacement of succinonitrile by the IL eliminated the abrupt change in the slope of the log σ vs T –1 plot at the melting temperature of the succinonitrile–LiI–I2 system, showing the Vogel–Tamman–Fulcher-type behavior owing to molecular chain disorder. Raman spectroscopy showed the I3 – concentration nearly twice the I5 – concentration for the OCE. Vibrational spectroscopy exhibited red shifts in the νCN, νCH2 , νa,CC, νa,N‑CH3 , and νs,N‑butyl modes, indicating an interaction between succinonitrile and the IL. The area ratio A CH2 /A CN increased slightly for x = 10 mol % (OCE) and largely for x > 10 mol %, indicating an increase in the C–H bond length. These observations indicated that the interaction between succinonitrile and the IL was enhanced at x > 10 mol %, which decreased the electrical conductivity of these electrolytes. Owing to fast ion transport, an OCE-based dye-sensitized solar cell showed a 40–55% decrease in the charge-transfer and Warburg resistances, resulting in ∼139 and ∼122% increases in J SC and η, respectively.

“…Accordingly, it is desirable to use a single-ion-conducting gel polymer electrolyte in which the cations are immobilized to the polymer backbone and the anions (I -) are highly mobile. Among the single-ion-conducting electrolytes, polymeric ionic liquids represent an important class of polymer electrolytes in which the cationic or anionic centers are confined to the repeating unit [20][21][22][23][24][25][26][27][28][29]. Although polymeric ionic liquid-based electrolytes have been extensively studied, their ionic conductivities are too low for practical applications at ambient temperature [30].…”

A polymeric ionic liquid, poly(1-methyl 3-(2-acryloyloxypropyl) imidazolium iodide) (PMAPII), was synthesized as a single-iodide-ion-conducting polymer and employed in a gel polymer electrolyte. Gel polymer electrolytes prepared from iodine, 4-tert-butylpyridine, γ-butyrolactone, and PMAPII were applied in quasi-solid-state dye-sensitized solar cells (DSSCs). The addition of 16 wt.% PMAPII provided the most favorable environment, striking a compromise between the iodide ion concentration and the ionic mobility, which resulted in the highest conversion efficiency of the resulting DSSCs. The quasi-solid-state DSSC assembled with the optimized gel polymer electrolyte exhibited a relatively high conversion efficiency of 7.67% under AM 1.5 illumination at 100 mA cm − 2 and better stability than that of the DSSC with a liquid electrolyte.
