摘要 采用热分解法制备Pt/ITO电极用于染料敏化太阳能电池(DSSC)。研究了热分解法相关工艺参数,包括烧结条件、不同的黏合剂以及黏合剂用量等。采用扫描电镜(SEM)分析了所制备的Pt/ITO对电极的表面形貌,通过循环伏安法(CV)对其电化学性能进行了表征。结果表明,采用适量羧甲基纤维素钠作为黏合剂,经5次烧结铂载量达到0235 mg/cm2时,Pt/ITO电极即对I-/I-3(I2)电对的氧化还原过程表现出良好的电催化活性。单体DSSC测试研究表明,所制备的低铂对电极的光电转换效率已接近铂片对电极的水平。

Abstract: Pt/ITO electrodes used in dye sensitized solar cell (DSSC) were prepared by thermal decomposition method. The processing parameters of thermal decomposition, such as the sinter conditions, different adhesives, usage of adhesive and so on, were investigated. The surface morphology of Pt/ITO counter electrode was analyzed by scanning electron microscopy (SEM), and the electrochemical performance was characterized through CV method. The results showed that with a suitable amount of CMC adhesive and a Pt loading of 0235 mg/cm2 after 5 times sintering, the electrode displayed nice catalytic activity to the redox reactions of I-/I-3(I2)The measurement of the single DSSC demonstrated that with the low Pt loading Pt/ITO electrode as counter electrode, the conversion efficiency of the cell approached to that with Pt sheet as counter electrode.
