    Novel branched coumarin dyes for dye-sensitized solar cells: significant improvement in photovoltaic performance by simple structure modification
    摘要:
    基于2D-π-A系统的分支香豆素染料的构建旨在优化光捕获能力并提升光伏性能。通过将不同单元(卡巴佐、氟烯和甲基)与具有不同分子体积和电子供给能力的π共轭连结体结合,获得了三种新型香豆素染料,分别编码为MS-C、MS-F和MS-M。通过分子工程,系统性地研究了它们的光捕获能力、能级和光伏性能。如预期所示,随着额外供体的引入,特别是利用强电子供体卡巴佐单元,MS-C的IPCE作用谱在390 nm至580 nm范围内保持高平台,值接近于1。随着IPCE的提高,三种染料的短路电流密度(Jsc)值从7.61 mA cm−2(MS-M)增加到13.47 mA cm−2(MS-C),增加幅度达到77%。使用DCA作为共吸附材料时,MS-M的Jsc有所增加,而分支的MS-C和MS-F的值则有所下降。这意味着源于分支供体的扭曲结构可以有效防止π聚集。更重要的是,通过引入额外的供体,开路电压(Voc)得到了显著提升。当构建分支的2D-π-A系统时,Voc从508 mV(MS-M)急剧增加到610 mV(MS-C)。综合来看,与线性MS-M(2.74%)相比,分支的MS-C在总体转换效率上实现了超过100%的提升(5.53%)。尽管这些染料的总体转换效率并不非常高,但这些结果仍将对未来开发高开路电压的高效香豆素敏化剂提供重要价值。

    We have developed new coumarin dyes having thiophene moieties in order to improve the photovoltaic performance of dye-sensitized nanocrystalline TiO2 solar cells based on the organic dyes as photosensitizers. A solar-energy-to-electricity conversion efficiency (η) of 7.7% was attained under AM 1.5 irradiation (100 mW cm−2) with a short-circuit current density (Jsc) of 14.3 mA cm−2, an open-circuit voltage (Voc) of 0.73 V, and a fill factor (ff) of 0.74.

  • Coumarin dyes containing low-band-gap chromophores for dye-sensitised solar cells
    作者:Kang Deuk Seo、Hae Min Song、Myung Jun Lee、Mariachiara Pastore、Chiara Anselmi、Filippo De Angelis、Mohammad K. Nazeeruddin、Michael Gräetzel、Hwan Kyu Kim

    日期:2011.9
    A series of coumarin dyes containing a low-band-gap chromophore of ethylenedioxythiophene (EDOT), which comprises a coumarin moiety as the electron donor and a cyanoacrylic acid moiety as electron acceptor in D-pi-A chromophores, were developed for use in dye-sensitised solar cells (DSSCs). These coumarin dyes have been used to fabricate DSSCs using I-/I-3(-) liquid electrolytes and their device performances were compared with that of NKX-2677 as a standard dye. Even though HKK-CM2 and HKK-CM3 have more extended aromatic units than HKK-CM1, the degree of pi-conjugation in HKK-CM2 and HKK-CM3 is less efficient than that of HKK-CM1, due to the relatively larger torsion angle between the plane of the donor and that of the acceptor. It is also in a good agreement with Density Functional Theory (DFT) calculations. As a result, a solar cell based on HKK-CM1 sensitiser shows better photovoltaic performance with J(SC) 0114.2 mA cm(-2), V-OC of 0.60 V, and a fill factor of 0.70, corresponding to an overall conversion efficiency eta of 6.07% under the standard AM 1.5 irradiation, than HKK-CM2 and HKK-CM3-based solar cells.
