摘要：

Diverse fused thiophenes with electron-rich and electron-deficient blocks have been synthesized and employed as the pi-conjugated spacers of organic dyes for the dye-sensitized solar cells (DSSCs). The effects of these fused thiophenes were investigated by their absorption spectra, electrochemical and photovoltaic properties. For a typical device a maximum power conversion efficiency of 6.11% was obtained under simulated AM 1.5 irradiation (100 mW cm(-2)): a short-circuit current (J(SC)) of 14.47 mA cm(-2), an open-circuit voltage (V-OC) of 670 mV, and a fill factor (FF) of 0.63.
