摘要
本文报道了一种热分解制备多孔ZnO纳米晶的方法,将多孔ZnO纳米晶经过不同退火温度处理后,研究其结构对染料敏化太阳能电池的光电转换性能的影响。通过扫描电镜(SEM)、透射电镜(TEM)、X-射线衍射仪(XRD)、N2吸附-脱附曲线分析等测试,研究了不同退火温度对ZnO形貌和晶化结构的影响,并通过紫外-可见吸收谱、J-V曲线和IPCE探讨了ZnO基太阳能电池在不同退火温度下的光吸收和光电转化性能。结果表明,随着退火温度升高,纳米ZnO光阳极的比表面积降低,孔容降低,界面电阻增大,光生电子-空穴复合增强;纳米ZnO光阳极在300℃退火表现出较佳的光电性能,相对于500℃光电转化效率提高了369.8%。
Porous ZnO powder was synthesized by a thermal decomposition method and characterized by SEM, XRD and N_2 adsorption-desorption for ZnO morphology and crystal structure, which was further fabricated as the photoanode of dye-sensitized solar cell(DSCs). The photoelectric properties of porous ZnO electrodes with different annealing temperatures were investigated by J-V curves and IPCE. The results showed that, with the increasing of ZnO annealing temperature, the BET surface area and pore volume of ZnO nanocrystals decreased, and the interface resistance and the recombination of electron-hole increased in the solar cell device, and the porous ZnO nanocrystals annealed at 300℃ have optimum photoelectric properties 369.8% higher than that of 500℃.
