New dipolar compounds containing a 5,6-bis-hexyloxy-benzo[2,1,3]thiadiazole entity in the conjugated spacer between the electron donating arylamine and the electron accepting 2-cyanoacrylic acid have been synthesized. These compounds were used as the sensitizers for efficient dye-sensitized solar cells. Compared to the congeners without the hexyloxy chains, the new dyes effectively suppress the dark currents and significantly improve the cell performance. The best conversion efficiency reached ∼92% of the N719-based standard DSSC fabricated and measured under similar conditions (AM 1.5 irradiation).
合成了新的偶极化合物,其在给电子芳基胺和受电子2-氰基丙烯酸之间的共轭间隔基中含有5,6-双己氧基-苯并[2,1,3]噻二唑实体。这些化合物被用作高效染料敏化太阳能电池的敏化剂。与不含己氧基链的同系物相比,新型染料有效抑制暗电流并显着提高电池性能。在类似条件(AM 1.5 辐照)下制造和测量的基于 N719 的标准 DSSC 的最佳转换效率达到约 92%。
