摘要
To meet the requirement of high efficient sensitizers of quasi-solid dye-sensitized solar cells(Qs-DSSCs) with reduced film thickness, a novel D-A-π-A configuration organic sensitizer IQ22 was specifically designed, in which the conjugation bridge of cyclopentadithiophene(CPDT) unit was incorporated to widen the light response and enhance molar coefficients for increasing the short-circuit current density(J_(SC)), and the octane chain on CPDT was targeted for suppressing the charge recombination and improving the open-circuit voltage(V_(OC)).Qs-DSSC based on IQ22 exhibits very promising conversion efficiency as high as 8.76%, with a J_(SC) of 18.19 mA cm~(-2), V_(OC) of 715 mV, and fill factor(FF) of 0.67 under AM 1.5 illumination(100 mW cm~(-2)).
