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 dye-sensitized 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 ~50m2·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(Voc) 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.
