In previous study we found that NBR(acrylonitrile butadiene rubber)/ionic liquid base electrolyte enhanced the ionic conductivity by plasticizing effect of ionic liquid. In this study, we prepared NBR(acrylonitrile butadiene rubber)/LiI/I2 based solid polymer electrolyte doped with zwitterionic liquid(4-(1-allyl-1H-imidazol-3-ium-3-yl)butane-1-sulfonate) showing plasticizing effect and applied to dye-sensitized solar cells(DSSC). We investigated the effect of ionic conductivity of NBR as added zwitterionic liquid(ZIL). The effect of ZIL was examined by using FT-IR, SEM, DSC, XRD characterization methods. We concluded that the addition of ZIL acts as a reduction in the crystallinity of the solid polymer electrolyte and the overall energy conversion efficiency of DSSC was also confirmed by solar simulator. |
