New metal-free organic sensitizers containing a fluorene unit as a π-conjugated system, a diphenylamine as an electron donor, and a cyanoacrylic acid moiety as an electron acceptor were synthesized and used for dye-sensitized solar cells. The photophysical and electrochemical properties of these dyes were investigated, and their performances as sensitizers in solar cells were measured. One solar cell containing the n-hexyl group in the fluorene unit produced an η of 5.15% (Jsc = 9.69 mA cm-2, Voc = 0.77 V, and ff = 0.70) under 100 mW cm-2 simulated AM 1.5 G solar irradiation (100 mW cm-2).
