efficiently and (ii) enhancing the intramolecular charge separation in the dye and
retarding charge recombination of the injected electrons with dye cations. Moreover, a TiO 2 DSSC based on a perylene sensitizer DYE6 bearing two thiophenol
groups exhibited an η value of 6.8% with an IPCE value of 87%, a J sc value of
12.60 mA cm
−2 , a V oc value of 728 mV, and a ff value of 0.74 under AM 1.5
simulated sunlight (Li et al. 2008).
