摘要: 用水热法制备了具有典型锐钛矿晶型的TiO₂纳米材料,采用Cr(NO₃)3对TiO₂薄膜电极进行修饰改性。用X射线衍射(XRD)、扫描电子显微镜(SEM)和光电子能谱(XPS)测试电极的物相及表面结构,结果显示TiO₂薄膜表面包覆一层粒径较大的氧化铬颗粒,整个电极仍保持均匀的多孔结构。电流-电压(I-V)曲线测试结果显示,改性后最佳电极的短路电流和光电转换效率分别比改性前提高了31.1%和40.4%。用电化学阻抗谱(EIS)测试电池的界面特性,从测试结果可以看出,相同偏压下,改性后电池的TiO₂/染料/电解质界面电阻更大,说明氧化铬包覆层在一定程度上抑制了界面的电子复合,改善了电池的光电输出特性。

Abstract: TiO₂ nanomaterial with typital anatase was prepared by hydrothermal method. Asurface modification method was carried out by over layer coating on the surface of TiO₂ thin film using Cr(NO₃)₃. The surface phase and morphology of electrodes were characterized by X ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The results showed that a layer of chromium oxide with larger particles was coated on TiO₂ thin film and the electrode remains homogeneous porous structure. The current-voltage (I-V) curves revealed that short circuit current and photoelectric transfer efficiency of the optimal modified electrode enhanced by 31.1% and 40.4% respectively more than before. Interface characteristics of cells were discussed using EIS. Seen from the results, the resistance of TiO₂/dye/electrolyte interface of modified electrode was much larger than before at the same bias. It is indicated that chromium oxide coating on TiO₂ thin film suppressed the charge recombination reactions and improved the performance of DSSCs.
