摘　　要：Three novel triarylamine dyes（AFL1-AFL3） containing fluorenyl and the biphenyl moieties have been designed and synthesized for application in dye-sensitized solar cells.The light-harvesting capabilities and photovoltaic performance of these dyes were investigated systematically through comparison of different π-bridges.The dye with a furan linker exhibited a higher open-circuit voltage（VOC） and monochromatic incident photon-to-current conversion efficiency（IPCE） compared to thiophene and benzene linker.Thus,AFL3 containing a furan linker exhibited the maximum overall conversion efficiency of 5.81%（VOC = 760 mV,JSC = 11.36 mA cm^-2 and ff=0.68） under standard global AM 1.5 G solar condition.Three novel triarylamine dyes（AFL1-AFL3） containing fluorenyl and the biphenyl moieties have been designed and synthesized for application in dye-sensitized solar cells.The light-harvesting capabilities and photovoltaic performance of these dyes were investigated systematically through comparison of different π-bridges.The dye with a furan linker exhibited a higher open-circuit voltage（VOC） and monochromatic incident photon-to-current conversion efficiency（IPCE） compared to thiophene and benzene linker.Thus,AFL3 containing a furan linker exhibited the maximum overall conversion efficiency of 5.81%（VOC = 760 mV,JSC = 11.36 mA cm^-2 and ff=0.68） under standard global AM 1.5 G solar condition.
