“…Alternative approaches of using polymer electrolytes were reported earlier to overcome scale up challenges inherent with the liquid electrolyte based devices [11][12][13]. Ever since, different approaches were attempted with the use of ionic liquids or polymer gel electrolytes (PGEs) [14][15][16]. By using PAN-VA (poly(acrylonitrile-co-vinyl acetate)) co-polymers, the highest conversion efficiencies up to 10.5% were reported [17].…”

“…PGEs, a potential alternative to liquid and solid electrolytes, have high ionic conductivity and good stability. This is because the polymer matrix in PGEs can effectively trap the liquid solvent to inhibit evaporation and meanwhile provide channels for fast transport of redox couples [14][15][16]. Therefore, photovoltaic performances of the DSSCs fabricated with some specialized PGEs were found to be comparable to those of solar cells based on liquid electrolytes.…”

Phthaloylchitosan-based gel polymer electrolytes were prepared with tetrapropylammonium iodide, Pr4NI, as the salt and optimized for conductivity. The electrolyte with the composition of 15.7 wt.% phthaloylchitosan, 31.7 wt.% ethylene carbonate (EC), 3.17 wt.% propylene carbonate (PC), 19.0 wt.% of Pr4NI, and 1.9 wt.% iodine exhibits the highest room temperature ionic conductivity of 5.27 × 10−3 S cm−1. The dye-sensitized solar cell (DSSC) fabricated with this electrolyte exhibits an efficiency of 3.5% withJSCof 7.38 mA cm−2,VOCof 0.72 V, and fill factor of 0.66. When various amounts of lithium iodide (LiI) were added to the optimized gel electrolyte, the overall conductivity is observed to decrease. However, the efficiency of the DSSC increases to a maximum value of 3.71% when salt ratio of Pr4NI : LiI is 2 : 1. This cell hasJSC,VOCand fill factor of 7.25 mA cm−2, 0.77 V and 0.67, respectively.

“…Within few years, the energy conversion efficiency of such cells has been improved to 12% [2][3][4]. Although, at present, these liquid electrolyte-based solar cells have reached an efficiency of about 14% [5], and quasi-solid state configuration have attracted much attention due to their better stability, non-flammability, negligible vapor pressure, and simpler cell preparation techniques [6][7][8][9]. Although the performance of dye-sensitized PECSCs is largely governed by the charge transport and the nature of the ions in the electrolyte [10][11][12], detailed studies of these aspects are lacking in the literature.…”

Performance of dye-sensitized nano-crystalline TiO 2 thin film-based photo-electrochemical solar cells (PECSCs) containing gel polymer electrolytes is largely governed by the nature of the cation in the electrolyte. Dependence of the photovoltaic performance in these quasi-solid state PECSCs on the alkaline cation size has already been investigated for single cation iodide salt-based electrolytes. The present study reports the ionic conductivity dependence on the nature of alkaline cations (counterion) in a gel polymer electrolyte based on binary iodides. Polyacrylonitrile-based gel polymer electrolyte series containing binary iodide salts is prepared using one of the alkaline iodides (LiI, NaI, KI, RbI, and CsI) and tetrapropylammonium iodide (Pr 4 NI
