Replacement of the difluorenylaminophenyl group by julolidine as the donor moiety in 20 decreased the efficiency to 2.95% thereby .This effect was assigned to the lower molar extinction coefficient compared to fluorenylphenylamino- substituted dyes. An increased overall power conversion efficiency of 4.5% was obtained by introduction of a coumarin unit into the fluorenylthiophene backbone of 21.
Grtzel and co-workers reported an efficiency of 8.0% with dye 22, which contains a fused dithienothiophene unit with a difluorenylaminophenyl donor and a cyanoacrylic acid acceptor
