  Benzothiadiazole-Based D−π-A−π-D Organic Dyes with Tunable Band Gap: Synthesis and Photophysical Properties

  摘要：

  A series of symmetrical D-pi-A-pi-D molecules based on benzothiadiazole and oligo(thienylenevinylene)s were facilely developed. The investigation of their photophysical and electrochemical properties demonstrated that these compounds exhibited broad absorption covering the whole visible range with appropriate energy levels for light-harvesting donors.

  用于染料敏化太阳能电池的含苯并噻二唑的D-π-A共轭化合物：合成，性质和光伏性能

  摘要：

  通过简便的合成方法为染料敏化太阳能电池开发了两个D - π -A共轭分子BzTCA和BzTMCA。对BzTCA和BzTMCA在稀溶液和薄膜中的光物理性质的研究表明，它们的吸收表现出对太阳光谱的广泛覆盖。BzTCA和BzTMCA的吸收特征在溶液中约710 nm处开始，在固态时约800 nm处开始。最大吸收（λ最大）为既BzTCA和BzTMCA在TiO 2胶片几乎与稀溶液中的胶片相同。发现它们的HOMO和LUMO在这些染料的中心部分重叠，从而确保了供体和受体之间的明显相互作用。对由BzTCA和BzTMCA制成的染料敏化太阳能电池性能的研究表明，功率转换效率分别为6.04％和4.68％，可以与普通的敏化剂N3相媲美。BzTMCA显示出较低的入射光子-电子转化效率（IPCE）和Ĵ SC相对于值BzTCA，这是可能是由于染料再生和电子注入过程中较弱的驱动力BzTMCA。IPCE响应区域达到近800

  AbstractThree novel low‐bandgap copolymers containing alkylated 4,7‐dithien‐2‐yl‐2,1,3‐benzothiadiazole (HBT) and different electron‐rich functional groups (dialkylfluorene (PFV‐HBT), dialkyloxyphenylene (PPV‐HBT) and dialkylthiophene (PTV‐HBT)) were prepared by Horner polycondensation reactions and characterized by 1H NMR, gel permeation chromatography, and elemental analysis. The alkyl side chain brings these polymeric materials good solubility in common organic solvents, which is critical for the manufacture of solar cells in a cost‐effective manner. The copolymers exhibit low optical bandgap from 1.48 to 1.83 eV. The highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels of the copolymers were measured by cyclic voltammetry. Theoretical calculations revealed that the variation laws of HOMO and the LUMO energy levels are well consistent with cyclic voltammetry measurement. The bulk heterojunction photovoltaic devices with the structure of ITO/PEDOT‐PSS/polymer:PCBM/LiF/Al were fabricated by using the three copolymers as the donor and (6,6)‐phenyl‐C61‐butyric acid methyl ester (PCBM) as the acceptor in the active layer. The device based on PTV‐HBT:PCBM (1:4 w/w) achieved a power conversion efficiency of 1.05% under the illumination of AM 1.5, 100 mW/cm2. © 2011 Wiley Periodicals, Inc.
