Abstract
Polyvinylidenefluoridecohexafluoropropylene PVDFHFP nanofibers were prepared by the electrospinning method and used as polymer electrolytes in dyesensitized solar cells DSSCs The electrolyte uptake and ionic conductivity of electrospun PVDFHFP nanofibers with different diameters changed significantly regardless of the nanofiber thickness The PVDFHFP nanofibers prepared from a 15 wt spinning solution showed high ionic conductivity 1295 S/cm and electrolyte uptake 947 DSSCs based on the 15 wt PVDFHFP nanofiber electrolyte showed an electron transit time of 634 × 10−3 s electronic recombination time of 588 × 10−2 s and conversion efficiency of 313 Thus we concluded that the electrospun PVDFHFP nanofibers can be used as polymer electrolytes in flexible DSSCs as wellThis work was supported by the Human Resources Development of the Korea Institute of Energy Technology Evaluation and Planning KETEP grant funded by the Korea Government Ministry of Knowledge Economy No 201140100090 This research supported by the Technology Innovation Program funded by the Ministry of knowledge Economy
