摘要:

报道了一种基于硫族金属复合物N4H9Cu7S4前驱体溶液制备硫化亚铜对电极的新方法. 分别制备了TiO2纳米颗粒多孔薄膜和TiO2纳米棒阵列结构的光阳极, 并在此基础上研究了基于硫化亚铜对电极的CdS/CdSe量子点敏化太阳电池的光电性能, 同时结合电化学阻抗技术考察了硫化亚铜对电极的催化性能. 结果表明: 与铂电极相比, 本方法制备的硫化亚铜电极对多硫电解质具有更高的催化活性, 所组装的CdS/CdSe量子点敏化太阳电池具有更优的光伏性能.

Abstract:

Cu2S counter electrodes were prepared from the metal chalcogenide complex precursor using a novel method. A porous TiO2 nanoparticle film and TiO2 nanorod array photoanode were also fabricated. The corresponding CdS/CdSe-sensitized solar cells with the Cu2S counter electrode were assembled and their photovoltaic performances were studied. The catalytic performance of the Cu2S counter electrodes was investigated using electrochemical impedance spectroscopy. Compared with a platinum counter electrode, the Cu2S one exhibited higher catalytic activity and better photovoltaic performance in quantum dot-sensitized solar cells.

Key words: Quantum dot sensitization, Counter electrode, Cu2S, Metal chalcogenide complex, CdS, CdSe
