| 摘 要： | 用有机光敏染料敏化半导体,通过染料分子的吸附功能基团与半导体相互作用,使染料分子与半导体表面之间建立电性耦合,进行有效的电荷转移,可以形成有机-半导体复合新型光电功能材料。联吡啶钌络合物有较强的可见光吸收、氧化还原性能可逆、氧化态稳定性高,是一类性能优越的有机光敏染料。近来许多研究发现,羧酸联吡啶钌的强吸附与TiO2纳晶薄膜的大比表面相结合,导致光生电荷快速注入TiO2导带达到有效的电荷分离,得到了接近100%的单色光光电流效率1]。为研究联吡啶钌分子的不同吸附功能基团与TiO2纳晶薄膜表面的相互作用对提高光电性能的影响,本文报道苯基磷酸取代的联吡啶钌络合物敏化纳晶多孔TiO2薄膜的光电性能。

| Abstract: | Thiocyanato (4,4'-dimethy1-2,2-bipyridyl)(4'-phenylphosphonate-terpyridyl) ruthenium(Ⅱ) was prepared and characterized with respect to its absorption, luminecence, and emission lifetime. The new dye with phosphonate absorption group can act as efficient charge-transfer sensitizer for nanocrystalline TiO2 film illustrated by the high quantum yield of charge injection from the excited dye to the conduction band of TiO2. Nanocrystalline TiO2 film coated with monolayer of the prepared dye harvests visible light efficiently with the maximum LHE of 89.5% at 503 nm, And thus fabricated sensitized TiO2 solar cell have a light to electric energy conversion efficiency of 3.1%, with 0.66V open circuit photovoltage and 4.4 mA/cm2 short-circuit photocurrent. Study on the photocurrent action spectrum of the new dye sensitized TiO2 film shows that the absorption group of the sensitizer has a strong influence on the photoelectrical performance of the film electrode. |
