摘要

Poly(vinylidene fluoride)-polyacrylonitrile-based membranes containing Fe_2O_3 nanoparticles were prepared by electrospinning technique and characterized by HR-SEM, FTIR, and XRD analysis. The effect of electrolyte in the electrospun nanofibers on electrolyte uptake, ionic conductivity and porosity were studied. The electrospun membranes containing Fe_2O_3 showed an enhanced ionic conductivity than that of without Fe_2O_3. Among the prepared membranes, the membrane with 7 wt % Fe_2O_3 has the highest liquid electrolyte uptake of 562% and ionic conductivity of 6.81 × 10~(-2) S cm~(-1). The photovoltaic performance for open circuit voltage (V_(oc)), Short-circuit current density (J_(sc)), Fill factor (FF), and η of the DSSC fabricated with 7 wt % Fe_2O_3 are 0.77 V, 10.4 mA/cm~2, 0.62 and 4.9%, respectively.
