摘要：
The bidentate 2,2'-bithiazole moiety was strategically designed as the bridging unit for the new donor-acceptor dye, Alko1. Dye sensitized solar cells (DSSCs) made by Alkol bound with various metal ions have been examined. Upon complexing with ZnI2, the Zn(II)-Alko1 complex on TiO2 achieved both higher molar absorptivity and a red-shifted absorption peak, increasing the performance of DSSCs by similar to 23% (cf. metal ion free Alko1).
