Abstract

New dipolar compounds incorporating a dithieno[3,2-b:2',3'-d]thiophene unit as the electron donor, an oligothiophene moiety as the conjugated spacer, and 2-cyanoacrylic acid as the electron acceptor have been synthesized. These nonarylamine type metal-free organic compounds have been successfully used as the sensitizers of dye-sensitized solar cells (DSSCs). The conversion efficiencies of the DSSCs range from 3.54 to 5.15% under AM 1.5 G irradiation. The best efficiency reached approximately 70% of the ruthenium dye N719-based standard cell fabricated and measured under similar conditions.

摘要

已经合成了新型的偶极化合物，其包含一个作为电子供体的二噻吩并[3,2-b:2',3'-d]噻吩单元、一个作为共轭间隔物的寡聚噻吩部分和 2-氰基丙烯酸作为电子受体。这些非芳胺型无金属有机化合物已成功用作染料敏化太阳能电池（DSSC）的敏化剂。在 AM 1.5G 辐照下，DSSC 的转换效率范围为 3.54%至 5.15%。在类似条件下制造和测量的基于钌染料 N719 的标准电池的最佳效率约为 70%。
