| 摘 要： | 利用光电流作用谱、循环伏安等光电化学方法研究了染料RuL2(SCN)2: 2TBA (L＝2,2'-bipydine-4,4'-dicarboxylic acid)与聚3-甲基噻吩(P3MT)复合敏化电极的光电化学性质. RuL2(SCN)2: 2TBA/P3MT复合敏化TiO2纳米晶多孔膜电极比染料RuL2(SCN)2: 2TBA敏化TiO2纳米结构电极的光电转换效率大幅度提高. 复合敏化电极中存在p-n异质结有效地抑制了电子的反向复合, 减少了电子的损失.

| Abstract: | The photo-current conversion properties of the nanostructured ITO/TiO2/RuL2(SCN)2: 2TBA and ITO/TiO2/RuL2(SCN)2: 2TBA/P3MT (L＝2,2'-bipydine-4,4'-dicarboxylic acid) electrode were studied by the photocurrent action spectra, the photocurrent dependence of potential, cyclic voltammety and UV-Vis absorption spectra. The composite sensitization could avoid the back electron transfer and loss of electrons. The photo-current conversion efficiency of ITO/TiO2/RuL2(SCN)2: 2TBA/P3MT was improved compared with that of ITO/TiO2/RuL2(SCN)2: 2TBA. |
