    摘要:

    制备了一种新型的染料敏化太阳电池的光阳极,该电极由溶剂合成的具有高比表面积和良好光散射特性的ZnO介孔微球组成。采用X射线衍射、扫描电子显微镜、能谱仪及N2吸附脱附等手段,分析了介孔ZnO微球的结构和形貌。所得介孔微球尺寸在亚微米范围,比表面积约为50m2.g-1。将ZnO介孔微球成功应用到染料敏化太阳电池中,当光阳极为3μm时,组成的原型器件的短路电流密度约为4.5mA.cm-2,开路电压约为602mV,转换效率可达1.28%。研究结果表明,ZnO介孔微球是一种优异的染料敏化太阳电池的光阳极材料。

    Abstract:

    A novel ZnO photoanode with high specific surface area and good light scattering ability was fabricated for dyesensitized solar cells(DSSCs). The photoanode comprised of mesoporous ZnO microspheres which were prepared by a solvothermal process. The structures and morphologies of ZnO microspheres were measured and confirmed by means of x-ray diffraction ( XRD), scanning electron microscopy ( SEM ), energy dispersive spectrum ( EDS ), and multi-point Brunauer- Emmett-Teller(BET) analysis. ZnO microspheres are in sub-micrometer scale and have BET specific surface area of - m^2·g^-1. Furthermore, a - 3μm thick photoanode made from ZnO microspheres resultes in a preliminary short-circuit current density( Jsc ) of - 4. 5mA · cm^-2 with an open-circuit voltage (Vooc) of -602mV and a conversion efficiency of 1.28% in DSSCs. All these suggest that mesoporous ZnO microspheres can be an alternative and feasible photoanode material for DSSCs. Key words: ZnO; mesoporous microsphere; dye-sensitized solar cells (DSSCs)
