| 英文摘要 | In order to increase the electron-donating ability of the donor part of the organic dye, the dithiafulvenyl (DTF) group as an additional electron donor is introduced into a triphenylamine (TPA) unit to form a donor-donor (2D) structure in this paper. Two new organic dyes WD9 (one 2-cyanoacetic acid as an electron acceptor) and WD11 (two 2-cyanoacetic acids as electron acceptors) containing this DTF-TPA 2D structure are designed, synthesized and applied in dye-sensitized solar cells (DSSCs). It is found that the double donor structures (DTF-TPA) not only contribute to enhancement of the electron-donating ability, but also inhibit aggregation between dye molecules and prevent I-3(-) in the electrolyte from recombining with injected electrons in TiO2. Under AM 1.5G irradiation (100 mW cm(-2)), a maximum power conversion efficiency (eta) of 4.09% is obtained for the WD11-based DSSC, higher than that of DTF-free dye L0 (eta = 2.47%). These results have demonstrated that the incorporation of the DTF group into the organic dye will be an effective approach to develop high-performance metal-free organic dyes. |
