  具有三个同轴电荷传输通路的定向表面结构

  摘要：

  我们报告了一种直接在固体表面上构建具有三个同轴 π 堆栈的定向架构的合成方法。该方法使用正交动态键、二硫化物和腙、自组织表面引发聚合 (SOSIP) 和模板化堆叠交换 (TSE)。已证实与萘二亚胺、苝二亚胺、方酸、富勒烯、低聚噻吩和三苯胺的相容性。与由两个同轴通道组成的光系统相比，安装第三个通道可将光电流产生增加多达 10 倍。限制涉及无法进入 SOSIP 架构的巨型堆叠交换器（例如，被三个富勒烯包围的酞菁），以及可以提供折叠或交叉指型电荷转移架构而不是三个同轴通道的平面三元组。报道的三通道表面架构与今天一样复杂，其结构的方向性保证了对每个单独通道中具有多分量梯度的多通道架构的通用访问。报道的方法将使我们能够系统地解开表面结构中分子二元组和三元组的超快光物理学，并可能对开发概念上的创新光电器件有用。

  Synthesis of novel cyan-colored sensitizing dyes bearing squaric acid core and 2,3,3-trimethyl-indole as terminal moieties has been conducted in order to fabricate dye-sensitized solar cells based on nanoporous TiO2. It has been found that position of COOH functionality utilized for anchoring with TiO2 surface has a marked effect on solar cell performance. Carboxylic acid group directly substituted to indole ring gave about 5-fold higher conversion efficiency as compared to the dye when it was substituted in alkyl chain of the indole ring. Efficiency has been found to be hampered due to aggregation and enhancement in the efficiency was observed when dyes were used with chenodeoxycholic acid (CDCA). Using COCA and long alkyl substituent at the N-position of indole ring to prevent aggregation and enhanced TiO2 surface passivation, respectively, has achieved a solar conversion efficiency of 3.15% with a short circuit current density of 7.26 mA/cm(2), an open circuit voltage of 0.64 V and a fill factor of 0.68 for SQ-5 under standard AM 1.5 solar irradiation.

• Substituent effect in direct ring functionalized squaraine dyes on near infra-red sensitization of nanocrystalline TiO2 for molecular photovoltaics

  We have synthesized a series of novel blue colored symmetrical squaraine sensitizers with variable alkyl chain length for their application towards the fabrication of dye-sensitized solar cells (DSSCs). It has been found that an increase in the alkyl chain length substituted at N-position of indole ring exhibits enhanced electron diffusion length and electron life-time resulting in better passivation of nanocrystalline TiO2 surface leading to enhancement in the cell performance. Based on HOMO and LUMO energy measurement of squaraine dyes, it has been demonstrated that about 0.16 eV energy barrier is sufficient for electron injection from LUMO of dye to TiO2 conduction band and dye regeneration after photo-excitation. Performances of DSSCs using model squaraine dyes indicate that dodecyl alkyl substituent is optimum giving highest Voc and use of chenodeoxycholic acid along with the dye SQ-4 shows a photoconversion efficiency of 3.5% under AM 1.5 irradiation.
