摘要：

A new series of triazine-containing donor-pi-acceptor organic sensitizers (TCT-(7-19)) with broad absorptions and high molar extinction coefficients have been designed and synthesized based on our previous work. All these dyes were completely characterized by H-1 NMR, ESI-MS, EA, IR, UV-vis, and cyclic voltammetry. The photovoltaic performances of dye-sensitized solar cells (DSSCs) based on these dyes were investigated. The effect of conjugating length and terminating groups on the absorption properties and photovoltaic performances were discussed. An overall photon-to-electron conversion efficiency of 3.69% was achieved with the DSSC based on the dye TCT-13 (J(sc)=7.76 mA cm(-2), V-oc=691 mV, FF=68.8%) under AM 1.5G illumination (100 mW/cm(2)).
