| 英文摘要 | Given the convenient sealing of fiber-shaped dye-sensitized solar cells (FDSSCs), the electrolyte refreshing effect on the photo-electrochemical performance of FDSSCs was studied. The electron transport and interfacial recombination kinetics were also systematically investigated by electrochemical impedance spectroscopy. With increased electrolyte refreshing times from 0 to 10, the open-circuit voltage (V-oc) and fill factor (FF) increased, whereas the photocurrent density (J(sc)) and power conversion efficiency (PCE) significantly decreased. The increased V-oc was mainly ascribed to the electron recombination resistance (R-ct,R- WE) at the TiO2/electrolyte interface and electron lifetime. The decreased J(sc) and PCE were due to dye desorption and the increase of series resistance. Further investigation proved that Li+ played a vital role in increasing V-oc as electrolyte refreshing and Li+ had more significant impact than TBP (tert-butyl pyridine) on maintaining high V-oc. |
