【摘要】：采用水热法制备ZnO纳米棒(ZnO NRs),并将其作为光阳极应用于染料敏化太阳能电池(Dye-sensitized solar cells,简称DSSCs)中。主要研究了不同方法制备的ZnO种子层对水热合成的ZnO NRs及DSSCs性能的影响。采用XRD和SEM对ZnO种子层和ZnO NRs进行了表征,并测试了不同光阳极薄膜组装的DSSCs的短路电流密度-开路电压曲线(Short circuit current density-Open circuit voltage,简称J-V曲线)、电化学阻抗谱(Electrochemical impedence spectroscopy,简称EIS)和强制调制光电流谱(Compulsory modulation photocurrent spectrum,简称IMPS)、强制调制光电压谱(Compulsory modulation photovoltage spectrum,简称IMVS)。研究表明,由浸渍法制备的ZnO种子层水热合成的ZnO NRs垂直导电玻璃生长,长度为45μm,所组装的DSSCs的性能最佳,光电转换效率(Photoelectric conversion efficiency,简称PCE)为1.65%,开路电压(Open-circuit voltage,简称Voc)为0.62 V,短路电流密度(Short-circuit current density,简称Jsc)为5.80 m A/cm2,填充因子(Fill factor,简称为FF)为0.46。
[Abstract]:Preparation of ZnO nanorods by hydrothermal method (ZnO NRs), and as a photoanode for dye-sensitized solar cells (Dye-sensitized solar cells, referred to as DSSCs). The main effect of the ZnO on the seed layer prepared by different methods on the hydrothermal synthesis of ZnO NRs and DSSCs. The performance of NRs and ZnO seeds of ZnO were characterized by XRD and SEM, short circuit current density different photoanode assembly DSSCs curve and open circuit voltage test (Short circuit current density-Open circuit voltage, referred to as J-V curve), electrochemical impedance spectroscopy (Electrochemical impedence spectroscopy, referred to as EIS) and forced modulated photocurrent spectroscopy (Compulsory modulation photocurrent spectrum, referred to as IMPS), forced modulated photovoltage spectroscopy (Compulsory modulation photovoltage spectrum, referred to as IMVS). The results show that by impregnation prepared by hydrothermal synthesis of ZnO seed layer The ZnO NRs conductive glass vertical growth, the length is 45 m, the DSSCs assembled the best performance, the photoelectric conversion efficiency (Photoelectric conversion efficiency, referred to as PCE) is 1.65%, the open circuit voltage (Open-circuit voltage, referred to as Voc) is 0.62 V, the short-circuit current density (Short-circuit current density, referred to as Jsc) for 5.80 m A/cm2 the fill factor (Fill, factor, referred to as FF) is 0.46.
