Table 4.

Parameters for DSCs using electrolytes based on imidazolium ionic liquids with different lengths of a side chain. Data for multiple DSCs are given in Table S3 in the Supporting Information section.

Electrolyte 1,2	JSC/mA cm−2	VOC/mV	ff/%	η/%	Rel. η/% 3
DMII	2.31	362	63	0.53	9.5
EMII	2.47	344	62	0.52	9.3
PMIIc	3.01	315	62	0.59	10.5
BMIIc	3.40	301	59	0.61	10.9
HMII	3.14	316	60	0.60	10.7
Reference cell with dye N719	12.53	654	68	5.60	100

¹ The electrolyte compositions are LiI (0.18 M), I₂ (0.05 M), and IL (0.6 M) in MPN. ² Data for PMIIc and BMIIc are repeated from Table 2 for convenience. ³ All DSCs are referenced to N719 sensitized DSC. Relative efficiencies are given with N719 PCE set to 100% [61].
