染料敏化太阳电池因其成本低、稳定性好、工艺简便而备受关注.发展高性能、廉价的材料代替传统的贵金属铂对电极是当前染料敏化太阳电池领域的研究热点之一.二硫化钼纳米材料具有高比表面积和大量的催化位点,是较为理想的铂对电极替代材料之一,但较低的电导率限制了二硫化钼对电极性能的进一步提高.本文首次报道了由二硫化钼纳米材料与金属性的四硫化三钴复合制备染料敏化太阳电池对电极,该复合对电极可以利用水热方法一步合成.研究结果表明,使用该复合对电极的染料敏化太阳电池光电转换效率可达6.77%,接近于使用铂对电极的器件(7.14%),优于使用单一二硫化钼(4.64%)或四硫化三钴(5.11%)作为对电极的器件. Due to its low cost, good stability and simple process, dye-sensitized solar cells are attracting much attention.Development of high performance and low cost materials to replace the traditional noble metal platinum counter electrode is one of the hottest topics in the field of dye-sensitized solar cells. Molybdenum sulfide nanomaterials have high specific surface area and a large number of catalytic sites, which is one of the ideal substitutes for platinum counter electrode, however, the lower conductivity limit the further improvement of the electrode performance of molybdenum disulfide.This paper reports for the first time that Molybdenum disulfide nanomaterials and metallic tetragonal trisulphide complex prepared dye-sensitized solar cell counter electrode, the composite counter electrode can be synthesized by hydrothermal method in one step.The results show that the use of the composite counter-electrode dye-sensitized solar cell Photoelectric conversion efficiency of 6.77%, close to the use of platinum on the electrode device (7.14%), better than the use of a single molybdenum disulfide (4.64%) or trisulfide (5.11%) as a counter electrode device.
