Abstract

Copper nanowires (CuNWs) are used to prepare flexible, transparent conducting substrates due to their low cost and ease of fabrication on a large area. A CuNW/polymer composite substrate was prepared and vulcanized to create a novel flexible nano-CuS/polymer composite substrate. The physical and photovoltaic properties of the substrate can be controlled by tuning the concentration of CuNW dispersion during the preparation of CuNWs and nano CuS films. The nano-CuS-based composite substrate was used as an effective flexible counter electrode of a quantum-dot-sensitized solar cell (QDSSC) and resulted in a maximum cell efficiency of 1.01%.

摘要

铜纳米线（CuNWs）因其成本低且易于大面积制备而被用于制备柔性透明导电基板。制备了一种CuNW/聚合物复合基板并进行硫化，以创建一种新型柔性纳米CuS/聚合物复合基板。在制备CuNWs和纳米CuS薄膜过程中，通过调整CuNW分散体的浓度，可以控制基板的物理和光伏性能。基于纳米CuS的复合基板被用作量子点敏化太阳能电池（QDSSC）的有效柔性对电极，电池的最大效率达到了1.01%。
