Dye-Sensitized Solar Cells Using Polymer Electrolytes Based on Poly(vinylidene fluoride-hexafluoro propylene) Nanofibers by Electrospinning Method

摘要

The dye-sensitized solar cell (DSSC) devices using polymer electrolytes based on electrospun poly(vinylidene fluoride-hexafluoro propylene) (PVDF-HFP) nanofibers were fabricated and investiqated the photovoltaic performances. The electrospun PVDF-HFP nanofibers were prepared by various parameters such as; polymer concentrations, applied voltages, and tip to collector distances (TCD) by the electrospinning method. The open circuit voltage (V{sub}(oc)), short circuit current (J{sub}(SC) )-fill factor (FF) and overall power conversion efficiency (η) of DSSC devices using electrospun PVDF-HFP nanofibers were 0.7180-0.7420 V, 9.7200-10.8837 mA/cm{sup}2, 0.5610-0.6250, and 4 1700-5 0186% respectively. When 15 wt% of polymer concentration, 14 kV of applied voltage, and 14 cm of TCD is applied to fabricate the PVDF-HFP nanofiber, the electrospun PVDF-HFP nanofiber should be the regular diameter of a nanofiber, the power conversion efficiency of the DSSC device reached 5.0186% as the best result.
