| 摘要: 首先研究了介孔碳（MC）、碳纳米管（CNT）和不同MC/CNT质量比（mMC/mCNT）制备的MC-CNT二元复合材料对电极的光电转换效率（PCE），进一步加入预先水热合成的CuS纳米材料，制备出MC-CNT-CuS三元复合材料对电极，同时探讨了CuS添加量和膜厚对对电极PCE的影响。实验结果表明，当mMC/mCNT=3/2时，2种碳材料能最大程度地发挥协同作用，使电池性能最好，PCE达12.69%。再加入0.4 g CuS时PCE可进一步提高，且对电极印刷5层时最优，此时所组装的电池获得的PCE最高（13.18%）。 |

| Abstract: Mesoporous carbon (MC), carbon nanotube (CNT) and MC-CNT binary counter electrodes prepared with different MC/CNT weight ratios (mMC/mCNT) were first studied on the power conversion efficiencies (PCE). Further, CuS nanomaterials pre-prepared through hydrothermal method were added into, and then MC-CNT-CuS ternary counter electrodes were synthesized. The influence of CuS content as well as film thickness on the efficiency was also probed. The experimental results showed that when mMC/mCNT=3/2, the synergistic effect of the two carbon materials reached the maximum, resulting in the highest PCE of 12.69% for the binary MC-CNT counter electrode. The PCE after incorporation of 0.4 g CuS was improved to the highest value of 13.18% when the counter electrode was screen printed five times. |
