| 摘 要： | 铜锌锡硫(CZTS)半导体常作为对电极材料被应用于量子点敏化太阳能电池(QDSCs)中,然而效率一直低于4%。本文采用热注入法合成出纳米尺寸的CZTS并制成对电极(CZTS/FTO),用其组装的Cd Se QDSCs和Cd Se Te QDSCs的效率(PCE)分别达到了5.75%和7.64%。电化学阻抗谱、塔菲尔极化等表征证明电池效率的提高与CZTS良好的导电性及催化活性联系密切。

| Abstract: | Copper Zinc Tin Sulfide (CZTS) semiconductor has been used as counter electrode in QDSCs. However, the highest power conversion efficiency (PCE) of the corresponding QDSCs was lower than 4%. Herein, copper-deficient CZTSwas synthesized through modified hot-injection method. The as-prepared CZTSis made into counter electrode (CZTS/FTO). PCEs up to 5.75% and 7.64% for CZTS/FTObased CdSe and CdSeTe sensitized QDSCs are obtained, respectively. The excellent photovoltaic performance is associated with the good conductivity and catalytic activity of CZTS. Electrochemical impedance spectroscopy (EIS) and Tafel polarization are used to verify the good electrochemical properties of CZTS/FTO. |
