摘要:
采用Cu-BTC和三维网状石墨烯(3DGNs)对光阳极材料进行改性,通过提高光阳极的比表面积以及提供光生电子的快速输运通道,器件的短路电流和光电转换效率实现了显著的提高。采用SEM和XRD对复合光阳极的微结构进行分析,通过电流-电压曲线和入射光电流转化效率分析其光伏特性。通过调整光阳极中Cu-BTC,3DGNs和TiO2的质量分数实现各种组分的协同作用。优化后,器件的短路电流为(20.5±0.1)mA/cm2,开路电压为(680±2)mV,填充因子为(61.9±0.1)%,能量转换效率为(8.63±0.1)%。
Abstract:
Cu-BTC and three-dimensional graphene networks(3DGNs)were employed to modify the photoanode of dye sensitize solar cells(DSSCs), and the remarkably enhanced short circuit current and incident photon to current conversion efficiency have been achieved. The major reasons are the increased BET area of the resulting photoanode and the formed fast transport channel for the photoinduced electrons. The morphology of photoanode was analyzed by SEM and XRD, and the photocatalytic performances were detected by current-voltage curves and incident photon to current conversion efficiency and the synergy between the Cu-BTC, 3DGNs, and TiO2 can be achieved by adjusting the mass fraction. Moreover, the scattering ability of the photoanode to incident light also can be controlled by modulating the size of Cu-BTC. After optimizing the photoanode, the short circuit current, open circuit voltaic, fill factor and energy conversion efficiency of the as-prepared device reached(20.5±0.1)mA/cm2,(680±2)mV,(61.9±0.1)%,(8.63±0.1)%.
