    Novel Quinoxaline-Based Organic Sensitizers for Dye-Sensitized Solar Cells
    摘要:
    Novel quinoxaline-based organic sensitizers using vertical (RC-21) and horizontal (RC-22) conjugation between an electron-donating triphenylamine unit and electron-accepting quinoxaline unit have been synthesized and used for dye-sensitized solar cells (DSSCs), leading to the relatively high power conversion efficiencies of 3.30 and 5.56% for RC-21 and RC-22, respectively. This result indicates that the quinoxaline electron-accepting unit is quite a promising candidate In organic sensitizers.

    The high performances of dyesensitized solar cells (DSSCs) based on seven new dyes are disclosed.

    公开了基于七种新型染料的染料敏化太阳能电池(DSSC)的高性能。在此,报道了一系列有意设计的偶极有机染料的合成,电化学和光物理性质及其在DSSC中的应用。七种有机染料的分子结构由作为电子供体的三苯胺基,作为电子受体的氰基丙烯酸和集成在电子供体和受体部分之间的π共轭间隔基中的缺电子二苯基喹喔啉部分组成。基于染料DJ104的DSSC给出了8.06%的最佳整体电池性能;在相同的实验条件下,基于标准N719染料的DSSC的效率为8.82%。由于强大的内部电荷转移跃迁以及缺电子的二苯基喹喔啉降低这些有机染料的能隙的作用,入射光子-电子转换效率的光谱范围扩展到了近红外区域的起点。在这些有机染料中,结合的四苯基链段作为疏水性屏障有效地减慢了TiO 2与电解质之间的电荷复合,并提高了光电压,这与它们的Ru II相当同行。详细的光谱研究揭示了染料结构与电池性能的相关性,从而可以在未来设计高效的光收集有机染料。

    1-dicyanomethylene) rhodamine (DCRD) as the electron acceptor/anchoring group, respectively, in combination with a N-annulated perylene electron donor and a quinoxaline auxiliary acceptor were investigated for application in dye-sensitized solar cells (DSCs) and dye-sensitized photocatalytic hydrogen production. The results showed that the sensitizer with cyanoacrylic acid (YFT-1) based DSCs showed a higher

  • Structural engineering of dipolar organic dyes with an electron-deficient diphenylquinoxaline moiety for efficient dye-sensitized solar cells

    A series of new organic dyes containing an electron-deficient diphenylquinoxaline moiety was synthesized and employed as the photosensitizers in dye-sensitized solar cells (DSSCs). The multiple phenyl rings in the peripheral positions of the dye structure provide a hydrophobic barrier to slow down the charge recombination. The photophysical and electrochemical properties of these dyes were investigated in detail. The cell performance and the associated photophysical and electrochemical properties can be easily tuned by the modification of the aromatic fragments within the pi spacer. Dye CR204-based DSSC reached the best energy conversion efficiency of 6.49% with an open-circuit voltage of 666 mV, a short-circuit photocurrent density of 14.9 mA cm(-2), and a fill factor of 0.66. The IPCE of CR204-based DSSC covers the light-harvesting to NIR region. (C) 2014 Elsevier Ltd. All rights reserved.
