摘要

Cyclic ammonium-based ionic liquids containing pyrrolidinium, piperidinium, morpholinium-based cations are synthesized, and their thermal properties, viscosities, ion diffusion coefficients, charge transfer resistances, and photovoltaic properties are characterized. A DSSC electrolyte employing Pyr14 (1-butyl-1-methylpyrrolidinium iodide) gives an open circuit voltage of 0.685 V, a short-circuit current of 14.53 mA/cm2, and conversion efficiency of 6.52 % under light intensity of 100 mW/cm2 due to Pyr14 possesses the lowest viscosity and highest diffusion coefficient. The DSSC based on Pip14 exhibited 5.55 % conversion efficiency, which is smaller than that of Mor14 (η = 6.19 %) due to an oxygen atom substitutes for a carbon atom.
