摘要 以在导电玻璃(FTO)上电沉积制备的Ru、Pd对电极为研究对象,通过使用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、循环伏安(CV)、交流电化学阻抗(AC)分别对Ru、Pd对电极进行表征和分析。研究结果表明:电沉积Ru作为染料敏化太阳电池(DSSC)对电极展现出良好的性能,在AM1.5G的光强下,短路电流达到14.91 mA/cm2,虽然填充因子相对较低(0.541),但光电转换效率仍可达6.16%,高于相同条件下的Pt(6.02%),说明Ru电极有望成为DSSC对电极铂的有力替代者。 Electrodeposited Ru, Pd on FTO counter electrodes were successfully prepared under constant current electrodepostion. The as-prepared electrodeposited Ru, Pd counter electrodes were characterized by scanning electron microscope, X-ray diffraction, and cyclic voltammetry and AC electrochemical impedence. After the dye-sensitized solar cells (DSSCs) with Ru and Pd as counter electrode (CE) were assembled, both the devices exhibited excellent photovoltaic performance under full sunlight illumination (100 mW/cm2, AM1.5G) , especially DSSC with Ru as CE showsl4.91 mA/cmZcurrent density, 6.16% photovohaic conversion efficiency, which is higher than that of DSSC with Pt CE (6.02%) under the same experimental condition, although the fill factor (0.514) is comparatively low. The facile procedure and excellent photovohaic properties allow Ru electrode to be alternative CE used in DSSCs.
