Description |
In this work, eight new ionic liquids (ILs) based on triethylammonium (TEA) or n-methylpiperidinium
(NMP) cations and perfluoro carboxylate (PFC) anions having different carbon chain lengths are synthesized
and their physico-chemical properties such as density, decomposition temperature, viscosity
and conductivity are determined. Photovoltaic characteristics of dye-sensitized solar cells (DSSCs) with
binary ionic liquids electrolytes, containing the mixture of the synthesized ILs and 1-methyl-3-propyl
imidazolium iodide (PMII) (v/v ¼ 35/65), are evaluated. Among the different ILs, solar cells containing
NMP based ILs show higher VOC than that of TEA, whereas, higher JSC is noted for the DSSCs incorporated
with the latter when compared to the former. Further, the photo-current of the DSSCs decreases with the
increase of the carbon chain length of perfluoro carboxylate anionic group of ILs. The cell performance of
the DSSC containing ternary ionic liquids-based electrolytes compose of NMP-2C/TEA-2C/PMII (v/v/
v ¼ 28/7/65) exhibits a JSC of 12.99 mA cm�2, a VOC of 639.0 mV, a FF of 0.72, and a cell efficiency of 6.01%.
The extraordinary durability of the DSSC containing the above combination of electrolytes stored in dark
at 50 �C is proved to be unfailing up to 1200 h.
