제목 Fabrications of Poly(vinylidene fluoride-hexafluoro propylene)/LiClO4 Nanofibers by Electrospinning Technique and Its Application to Dye-Sensitized Solar Cells
초록 We fabricated the electrospun poly(vinylidene fluoride-hexafluoro propylene) (PVDF-HFP) /LiClO4 nanofibers by the electrospinning method and applied as a polymer membrane on the Dye-sensitized solar cells (DSSCs). The Voc of the DSSC device using electrospun PVDF-HFP /LiClO4 nanofibers was 0.773 V, the Jsc was 9.77 mA/cm2, and the overall power conversion efficiency achieved up to 4.19 %. The photovoltaic performances of the DSSC device using electrospun PVDF-HFP nanofibers without LiClO4 were lower than those of devices using electrospun PVDF-HFP/LiClO4 nanofibers. To investigate the photovoltaic effect of different LiClO4 concentrations in electrolyte solutions, the electrospun PVDF-HFP nanofibers without LiClO4 were soaked into the electrolyte solution with different LiClO4 concentrations. An increase of concentration of LiClO4 in electrolyte solution results in a decrease of photocurrent and efficiency due to the desorption of dyes by LiClO4.
