Abstract

Hybrids based on a dibenzosuberene core bearing a spiro-fluorene junction at the C-5 position and with amino donor and β-thiophenyl-α-cyanoacrylic acid acceptor groups at C-3 and C-7, respectively, serve as new organic sensitizer materials for solar cell applications. Solar cell devices based on these materials show a conversion efficiency (η) of up to 6.1% (Voc = 697 mV, Jsc = 12.2 mA cm−2, FF = 0.72) under AM 1.5 G conditions. The best IPCE values exceed 75% within the 450–550 nm absorption range.
