Abstract

The synthesis conditions of ionic liquid 1-vinyl-3-propylimidazolium iodide (ViPrIm+I) and Poly(1-vinyl-3-propylimidazolium) iodide [P(ViPrIm+I)] were studied in this work. P(ViPrIm+I) as a single-ion conductor providing iodine was designed to develop a quasi-solid polymer electrolyte based on PVDF/PEO film for dye-sensitized solar cells (DSSCs). The samples were characterized respectively by high-performance liquid chromatography (HPLC), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance imaging (NMRI), gel permeation chromatography (GPC), etc. The results showed that the single-ion conducting quasi-solid polymer electrolyte (SC-QPE) exhibited high ionic conductivity of 1.86 × 10−3 S cm−1 at room temperature measured by CHI660C Electrochemical Workstation. Moreover, solar cells assembled using the SC-QPE yielded an open-circuit voltage of 0.83V, short-circuit current of 8.01 mA cm−2 and the conversion efficiency of 2.42%. © 2010 Wiley Periodicals, Inc.
