Photovoltaic properties of the DSCs with MWNT-PAni/PMII composite electrolyte and with bare PMII electrolyte using Pt/ITO as counter electrode^a.

Electrolyte	𝐽SC (mA cm^−2)	𝑉OC (V)	FF	𝜂 (%)
PMII	1.32	0.602	0.33	0.26
MWNT-PAni/PMII	9.87	0.560	0.57	3.15
Liquid electrolyte^b	15.21	0.701	0.72	7.68

^aConditions: sealed cells; dye: N719; coadsorbate: DCA 40 mM; photoelectrode: TiO₂ (0.25 cm²); irradiated light: AM 1.5 solar light (100 mWcm⁻²). 𝐽_SC: short-circuit photocurrent density; 𝑉_OC: open-circuit photovoltage; FF: fill factor; η: total power conversion efficiency. ^bLiquid electrolyte was composed of 0.6 M dimethylpropyl-imidazolium iodide (DMPII), 0.05 M I₂, and 0.1 M LiI in acetonitrile.
