  Arylamine-Based Dyes for p-Type Dye-Sensitized Solar Cells

  摘要：

  New arylamine-based sensitizers for p-type dye-sensitized solar cells (DSSCs) have been synthesized and used for p-type DSSCs. The best conversion efficiency reaches similar to 0.1%. Sensitizers with two anchoring carboxylic acids lead to higher open-circuit voltages, short-circuit currents, and energy conversion efficiencies.

  A Versatile Synthesis of Long-Wavelength-Excitable BODIPY Dyes from Readily Modifiable Cyclopenta[2,1-b:3,4-b′]dithiophenes

  摘要：

  Knoevenagel condensation of a simple methylated borondipyrromethene (Bodipy) with 4,4'-dihexyl-4H-cyclopenta[2,1-b:3,4-b']dithiophenes functionalized at one end by a triphenylamine residue and at the other by a carbaldehyde fragment leads to novel dye species. These bisvinylic derivatives exhibit pronounced absorption in the visible range extending above 850 nm. Addition of other Bodipy units by coupling to a central iodophenyl entity enables filling of the gaps in absorption of the pivotal starting material. Efficient cascade energy transfer between the Bodipys is facilitated by spectral overlap between the energy donor and the energy acceptor. All photons between 350 nm and 750 nm are channeled to the distyryl centers which emit at 864 nm.

  Three dithieno[3,2-b:2',3'-d]pyrrole (DTP) units with different hexyloxyphenyl (HOP) substituents have been developed for triphenylamine organic dyes (XS54-XS56). The introduction of the 4-HOP-DTP unit has resulted in a stronger light harvesting capacity, accounting for the observed photocurrent enhancement in the case of XS54, while the 2-HOP-DTP/2,4-HOP-DTP units induce a strikingly large photovoltage

  solar cells is a short electron diffusion length, which is due to fast recombination between electrons in the TiO2 electron-transporting layer and holes in the 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) hole-transporting layer. In this report, the sensitizing dye that separates the TiO2 from the Spiro-OMeTAD was engineered to slow recombination and increase device

  固态染料敏化太阳能电池的主要限制是电子扩散长度短，这是由于TiO 2电子传输层中的电子与2,2'，7,7'-四原子中的空穴之间的快速复合（N，N-二-对甲氧基苯胺）-9,9'-螺双芴（Spiro-OMeTAD）空穴传输层。在本报告中，分离TiO 2的增感染料Spiro-OMeTAD的产品经过精心设计，可减慢重组速度并提高设备性能。通过合成和表征三种新型有机D-π-A增感染料（WN1，WN3和WN3.1），发现烷基链在增感染料上的数量和位置在抑制重组中起着重要作用。在使用Spiro-OMeTAD作为空穴传输材料的固态设备中，这些染料实现了以下效率：WN1达到4.9％，WN3达到5.9％，WN3.1达到6.3％，而Y123则达到了6.6％。参考染料。在这项研究中研究的染料中，使用瞬态光电压和光电流测量，WN3.1被证明在抑制固态染料敏化太阳能电池中的重组方面最有效。
• A hybrid electron donor comprising cyclopentadithiophene and dithiafulvenyl for dye-sensitized solar cells

  Two new photosensitizers featured with a cyanoacrylic acid electron acceptor (A) and a hybrid electron donor (D) of cyclopentadithiophene and dithiafulvenyl, either directly linked or separated by a phenyl ring, were synthesized and characterized. Both of them undergo two reversible oxidations and strongly absorb in the visible spectral region due to a photo-induced intramolecular charge-transfer (ICT) transition. To a great extent, the electronic interaction between the D and A units is affected by the presence of a phenyl spacer. Without a phenyl ring, the D unit appears more difficult to oxidize due to a strong electron-withdrawing effect of the A moiety. In sharp contrast, the insertion of the phenyl ring between the D and A units leads to a broken π-conjugation and therefore, the oxidation potentials remain almost unchanged compared to those of an analogue without the A group, suggesting that the electronic coupling between D and A units is relatively weak. As a consequence, the lowest-energy absorption band shows a slight hypsochromic shift upon the addition of the phenyl spacer, indicative of an increased HOMO–LUMO gap. In turn, the direct linkage of D and A units leads to an effective π-conjugation, thus substantially lowering the HOMO–LUMO gap. Moreover, the application in dye-sensitized solar cells was investigated, showing that the power conversion efficiency increases by the insertion of the phenyl unit.

  合成并表征了两种新的光敏剂，其特点是具有氰基丙烯酸电子受体（A）和由环戊二硫苯和二硫富烯基组成的杂化电子给体（D），可以直接连接或通过苯环分离。它们都经历了两次可逆氧化反应，并且由于光诱导分子内电荷转移（ICT）跃迁，在可见光谱区强烈吸收。D和A单元之间的电子相互作用在很大程度上受到苯基间距的影响。没有苯环时，由于A基团的强电子吸引作用，D单元更难氧化。相比之下，将苯环插入D和A单元之间会破坏π-共轭，因此氧化电位与没有A基团的类似物相比几乎不变，表明D和A单元之间的电子耦合相对较弱。因此，最低能量吸收带在加入苯基间距后显示出轻微的向蓝移，表明HOMO-LUMO间隙增加。相反，D和A单元的直接连接导致有效的π-共轭，从而大大降低了HOMO-LUMO间隙。此外，还研究了其在染料敏化太阳能电池中的应用，插入苯基单元可以提高其功率转换效率。
