采用简便的电化学沉积方法在染料敏化太阳能电池（DSSC）中制备了 ClO ― 4 ―聚（3,4-乙撑二氧噻吩）TiO 2 /氟掺杂氧化锡（ClO ― 4 ―PEDOT/TiO 2 /FrO）导电玻璃对电极（CE）。与ClO ― 4 ―PEDOT/FTO CE相比，光电流-电压测量表明，具有ClO ― 4 ―PEDOT/TiO 2 /FTO CE的DSSC的光电流转换效率（η）、填充因子和短路电流密度（J SC ）有所增加。电化学阻抗谱表明ClO ― 4 ―PEDOT/电解质界面上的电荷转移电阻降低。循环伏安法结果还表明，ClO ― 4 ―PEDOT/TiO 2 /FrO 电极比 ClO ― 4 ―PEDOT/FTO 电极表现出更高的 I ― 3 /I ― 氧化还原反应活性。
ClO ― 4 ―poly(3,4-ethylenedioxythiophene)TiO 2 /fluorine-doped tin oxide (ClO ― 4 ―PEDOT/TiO 2 /FrO) conduction glass counter electrode (CE) is fabricated in dye-sensitized solar cells (DSSCs) by using a facile electrochemical deposition method. Compared to the ClO ― 4 ―PEDOT/FTO CE, the photocurrent―voltage measurement reveals that the photocurrent conversion efficiency (η), fill factor, and short-circuit current density (J SC ) of DSSCs with a ClO ― 4 ―PEDOT/TiO 2 /FTO CE increase. Electrochemical impedance spectra indicate that the charge-transfer resistance on the ClO ― 4 ―PEDOT/electrolyte interface decreases. Cyclic voltammetry results also indicate that the ClO ― 4 ―PEDOT/TiO 2 /FrO electrode shows a higher activity toward I ― 3 /I ― redox reaction than that of the ClO ― 4 ―PEDOT/FTO electrode.
