| 摘 要： | 采用水热法制备了ZnO纳米棒,以ZnO纳米棒为原料制备出ZnO/TiO2纳米管晶膜电极并应用于染料敏化太阳能电池.用扫描电镜(SEM)、X射线衍射仪(XRD)、X射线能谱仪(EDX)和N2吸脱附分析等研究了样品的结构、表面形貌和化学组成,并通过紫外可见光度计和电化学工作站探讨了煅烧温度在80~600℃范围内ZnO/TiO2纳米管电极的光电化学性能.此外,研究经TiCl4化学处理的ZnO/TiO2纳米管电极光电性能的改善情况.结果表明,600℃煅烧的ZnO/TiO2纳米管电极制备的染料敏化太阳能电池表现出较优的光电性能,其短路电流密度(Jsc)为2.28 mA/cm2,开路电压(Voc)为0.631 V,光电转换效率η为0.66%.600℃煅烧的ZnO/TiO2纳米管经TiCl4处理后的染料敏化太阳能电池的光电性能得到显著改善,其光电转换效率η提高到1.06%.

| Abstract: | ZnO/TiO2 nanotubes were prepared using ZnO nanorods as raw materials,which were synthesized by hydrothermal methods.Then its performance as an electrode of a dye-sensitized solar cell was investigated.The obtained products were characterized by SEM,XRD,EDX and N2 adsorption.Furthermore,the photoelectric properties of ZnO/TiO2 nanotubes film electrodes calcined at different temperatures were investigated by UV-Vis adsorption spectra and electrochemical workstation.It is found that the DSSC based on ZnO/TiO2 nanotubes calcined at 600℃ have optimum photoelectric properties,Jsc=2.28 mA/cm2 and Voc= 0.631 V,yielding the 0.66% maximum conversion efficiency.Additionally,after TiCl4 posttreatment,the performance of DSSC made from ZnO/TiO2 nanotubes are improved obviously and the photoelectric conversion efficiency is up to 1.06%. |
