  Modified Phthalocyanines for Efficient Near-IR Sensitization of Nanostructured TiO₂ Electrode

  摘要：

  A zinc phthalocyanine with tyrosine substituents (ZnPcTyr), modified for efficient far-red/near-IR performance in dye-sensitized nanostructured TiO2 solar cells, and its reference, glycine-substituted zinc phthalocyanine, (ZnPcGly), were synthesized and characterized. The compounds were studied spectroscopically, electrochemically, and photoelectrochemically. Incorporating tyrosine groups into phthalocyanine makes the dye ethanol-soluble and reduces surface aggregation as a result of steric effects. The performance of a solar cell based on ZnPcTyr is much better than that based on ZnPcGly. Addition of 3alpha,7alpha-dihydroxy-5beta-cholic acid (cheno) and 4-tert-butylpyridine (TBP) to the dye solution when preparing a dye-sensitized TiO2 electrode diminishes significantly the surface aggregation and, therefore, improves the performance of solar cells based on these phthalocyanines. The highest monochromatic incident photo-to-current conversion efficiency (IPCE) of similar to24% at 690 nm and an overall conversion efficiency (eta) of 0.54% were achieved for a cell based on a ZnPcTyr-sensitized TiO2 electrode. Addition of TBP in the electrolyte decreases the IPCE and eta considerably, although it increases the open-circuit photovoltage. Time-resolved transient absorption measurements of interfacial electron-transfer kinetics in a ZnPoTyr-sensitized nanostructured 702 thin film show that electron injection from the excited state of the dye into the conduction band of TiO2 is completed in similar to500 fs and that more than half of the injected electrons recombines with the oxidized dye molecules in similar to300 ps. In addition to surface aggregation, the very fast electron recombination is most likely responsible for the low performance of the solar cell based on ZnPcTyr.

  Synthesis and Characterization of Peripherally Ferrocene-modified Zinc Phthalocyanine for Dye-sensitized Solar Cell

  摘要：

  为了在染料敏化纳米结构 $TiO_2$ 太阳能电池中实现高效的远红外/近红外性能，我们合成了外围二茂铁取代的酞菁锌（ZnPc-Fc）并对其进行了结构表征。在酞菁中掺入二茂铁可以极大地提高染料在极性有机溶剂中的溶解度，并减少由于大块二茂铁取代基的立体效应而导致的表面聚集。ZnPc-Fc 中二茂铁和酞菁之间的电子转移反应途径从 S1 状态的荧光完全熄灭（< 0.08% vs ZnPc）得到了证明。ZnPc-Fc 在二甲基亚砜（DMSO）中的瞬态吸收光谱在 542 和 682 纳米波长处观察到强烈的吸收带。此外，在 450 - 600 nm 和 750 - 850 nm 处出现的激发态吸收信号是由于酞菁阴离子形成了电荷分离态。经测定，ZnPc-Fc 中电荷分离态的寿命为 $170{\pm}8$ ps，比 ZnPc 短近 17 倍。
