We prepared electrospun polymer blend nanofibers by the electrospinning method and investigated about their applications to dye-sensitized solar cells(DSSCs). Quaternized poly(N-vinyl imidazole)(quaternized PVI) was synthesized by free radical polymerization. Electrospun quaternized PVI and poly(vinylidene fluoride-co-hexafluoro propylene)(PVDF-HFP) blend nanofibers were prepared and examined the uptake and the porosity. Also, their ionic conductivity and morphology were examined by impedance measurement and SEM, respectively. The best performance using the electrospun quaternized PVI/PVDF-HFP(1:3) blend nanofibers were 0.77 V, 8.69 mA/cm2, 0.65, and 4.29 % under AM 1.5. |
