Abstract:
Three new dyes ( 1 – 3 ) with a triarylamine electron donor, a cyanoacrylic acid moiety as both electron acceptor and anchoring group, and a fluorene‐9‐ylidene moiety as an antenna were synthesized, and their electrochemical, photophysical, and photovoltaic properties were evaluated. Despite minor differences in absorption properties, as the starburst shape of the dyes increases and highly hindered hydrophobic groups are introduced, the measured open‐cell voltage ( V oc ) increased noticeably from 0.79 to 0.83 V, and the power‐conversion efficiency (PCE) value increased from 3.98 to 4.73 %.
