摘要:
本文使用还原反应法制备载银凹凸棒土(Ag/AT)纳米复合颗粒,利用场发射扫描电子显微镜(FESEM)、X-射线能谱、X-射线衍射(XRD)对其纳米复合颗粒进行表征,并将其应用于染料敏化太阳能电池(DSSCs)中,进一步提高DSSCs的光电转化效率。通过FESEM观察了Ag/AT纳米复合颗粒在TiO2电极表面的分布情况,研究了不同粒径的Ag/AT纳米复合颗粒对TiO2电极的吸收光谱以及对DSSCs光伏性能的影响。

Abstract: Ag/AT nanocomposites were the preparation by chemical reduction for the application in DSSCs. The structure of the nanocomposites was characterized by Field Emission Scanning Electron Mi-croscope (FESEM), X-ray spectroscope and X-Ray Diffraction (XRD). The spectra absorption of TiO2 electrodes and the photovoltaic performance of dye-sensitized solar cells with different size distribution of Ag/AT nanocomposites were studied. In addition, the nanocomposites distributed in the TiO2 electrodes surface were observed through the FESEM.
