“…This significant enhancement of V oc with added Pr 4 NI, an iodide with relatively larger cation, can be attributed to the decrease of the recombination of electrons in the conduction band of TiO 2 with I 3 − in the electrolyte and to the shift of the resulting conduction band due to the cation adsorption by TiO 2 . A similar drop in V oc due to the large size cations, such as Pr 4 N + in the electrolyte in mixed cation systems has been reported by several other groups [11,17,20,22,26].…”

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

“…The TiO 2 photo-anode preparation has been described comprehensively in a previous work [26]. The dye adsorption to the double-layered TiO 2 film overlaid on FTO glass plates was conducted by immersing the TiO 2 -coated FTO plates in a 0.5 mM ethanolic solution of ruthenium 535-bis TBA (N719 dye).…”

“…Literature review reveals that solid polymer electrolytes have been widely studied as cation, mostly lithium ion, conductors with intention of applying as secondary batteries; however their utilization as anionic conductors is rather unexplored [5][6][7][13][14][15][16]. Anionic conductors are important not only for DSSCs but also for other electrochemical applications such as electrochromic devices and separation processes, which are also less studied [15,17].…”

“…One of the popular methods to increase the conductivity is the addition of plasticizers or co-solvents to the electrolyte complex [5,10,13,14]. Those plasticizers take part in enhancing the mobility of ions by lowering the local viscosity and thus increasing the segmental flexibility of polymer chains.…”

In this study, the electrical, dielectric and morphological analysis of composite solid polymer electrolytes containing polyethylene oxide, alumina nano-fillers and tetrapropylammonium iodide are conducted. The temperature dependence of conductivity shows activation energy of 0.23, 0.20 and 0.29 eV for electrolytes containing 0, 5 and 15 wt.% alumina, respectively, when data fitted to the Arrhenius equation. These activation energy values are in good agreement with those determined from dielectric measurements. The result confirms the fact that conductivity is activated by both the mobility and the charge carrier density. The conductivity isotherms demonstrated the existence of two peaks, at 5 and 15 wt.% Al 2 O 3 composition. The highest conductivity values of 2.4 × 10 −4 , 3.3 × 10 −4 and 4.2 × 10 −4 S cm −1 are obtained for the sample with 5 wt.% Al 2 O 3 at 0, 12 and 24°C, respectively, suggesting an enhancement of conductivity compared with that of alumina free samples.
