摘要：To achieve high power conversion efficiency(PCE),three porphyrin sensitizers have been synthesized and explored to simultaneously enhance the photocurrent(JSC)and photovoltage(VOC).On basis of the XW4,a benzothiadiazole(BTD)unit has been introduced to afford XW57 with the aim to extend the absorption wavelength and enhance the light harvesting ability.As a result,a JSC of 13.72 mA/cm^2 has been obtained for XW57,higher than that of XW4.On this basis,XW58 has been prepared by modifying the carbazole-based donor with two bulky dihexyloxyphenyl groups,and the superior anti-aggregation character raises the VOC from 781 mV(XW4)to 844 mV.When both the BTD unit and the bulky groups are introduced to the acceptor and donor units,respectively,the resulting sensitizer XW59 exhibits a highest PCE value of 7.34%with synergistically enhanced JSC of 13.19 mA/cm^2 and VOC of 793 mV.These results provide further insight into developing high performance dye-sensitized solar cells.
