摘要
采用均匀沉淀法制得的氧化铜纳米棒(CuO-NRs)与石墨烯(GNs)浆料复合,利用电流体动力学技术(EHD技术)在FTO导电玻璃基片上制备CuO-NRs/GNs复合对电极。通过XRD物相分析,和SEM、TEM结构表征,表明CuO-NRs/GNs复合薄膜具有多孔的网络结构,通过一系列电化学性能测试,证明CuO-NRs/GNs复合对电极具有较高的电催化活性,和较快的电子传输速率,由CuO-NRs/GNs复合对电极组装的DSSC光电转换效率(2.57%)达到了与Pt对电极(3.46%)相当的水平。
In this paper,copper oxide nanorods (CuO-NRs) prepared by uniform precipitation method were combined with graphene (GNs) slurry,and CuO-NRs/GNs composite counter electrodes were prepared on FTO conductive glass substrated by electrohydrodynamics (EHD).The XRD phase analysis and SEM,TEM structure characterization indicated that the CuO-NRs/GNs composite film had a porous network structure.It proved that the CuO-NRs/GNs composite counter electrode had high electrocatalytic activity and faster electron transport rate through a series of electrochemical performance tests,and achieved photoelectric conversion efficiency of DSSC assembled by CuO-NRs/GNs composite counter electrodes (2.57%) reached the same level as that of Pt counter electrodes (3.46%).
