| 摘要: 采用一步水热法制备TiO2纳米棒阵列,研究了无水乙醇作为前驱物替换去离子水对纳米棒阵列的形貌的影响。实验发现,当无水乙醇的含量达到100%的时候,在生长的TiO2纳米棒阵列的上面获得一层以TiO2纳米棒为基本单元的微米球,从而制备出TiO2复合纳米阵列薄膜。通过XRD和TEM发现,样品为单晶四方金红石结构TiO2构成的阵列薄膜,将样品组装成染料敏化太阳能电池后,电池的开路电压和短路电流分别为Voc=0.63V,Jsc=10.9mA·cm-2,填充因子FF=56.3%,转换效率达到η=4.1%。 |

| Abstract: TiO2 nanorod arrays were synthesized through the one-step hydrothermal process. The influence of deionized water to the morphology of nanorod arrays instead of absolute ethyl alcohol as precursor was also investigated. The results showed that a layer of TiO2 microsphere can be synthesized on the top of the nanorod arrays, which serve as the basic unit for the growth of microsphere and finally result in complex TiO2 nanorod arrays film. The XRDand TEMresults suggeste that the nanorod arrays film is consisted of single-crystalline TiO2with tetragonal rutile phase structures. After the assembling of dye sensitized solar cells with the as-synthesized samples, the open-circuit voltage and short-circuit current density and fill factor were measured out as Voc=0.63 V, Jsc=10.9 mA·cm-2 and FF=56.3%, respectively. The energy conversion efficiency (η) is approximately 4.1%. |
