Abstract :
We prepared electrospun polymer nanofibers by the electrospinning method and investigated about their applications to dye-sensitized solar cells (DSSCs). Electrospun poly(vinylidenefluoride–co-hexafluoropropylene) (PVDF–HFP) and PVDF–HFP/polystyrene (PS) blend nanofibers were prepared and examined the uptake, the ionic conductivity, and the porosity by impedance measurement and Scanning Electron Microscope (SEM). The best results of Voc, Jsc, FF, and efficiency of the DSSC devices using the electrospun PVDF–HFP/PS(3:1) blend nanofibers were 0.76 V, 11.8 mA/cm2, 0.66, and 5.75% under AM 1.5.
