Abstract :Two new metal-free organic dyes in D-π-A structure, containing a quinoline π-bridge and malononitrile insert ignore into journalissuearticles values(4a); and cyanoacrylic acid insert ignore into journalissuearticles values(4b); as acceptors, were synthesized for the first time to apply dye-sensitized solar cell insert ignore into journalissuearticles values(DSSC);. The structures of these compounds were elucidated by FT-IR, 1H NMR, 13C NMR techniques. The photophysical and photovoltaic properties of the obtained compounds were investigated and compared by current density–voltage insert ignore into journalissuearticles values(J–V); graphs. Compound 4b containing cyanoacrylic acid as an acceptor reached an open–circuit voltage insert ignore into journalissuearticles values(Voc); of 0.645 V, short–circuit current density insert ignore into journalissuearticles values(Jsc); of 6.66 mA cm-2 and fill factor insert ignore into journalissuearticles values(FF); of 0.70 in the presence of chenodeoxycholic acid insert ignore into journalissuearticles values(CDCA);, showing a power conversion efficiency insert ignore into journalissuearticles values(PCE); of 3.01%. It is also observed that the incorporation of thiomethyl group to the structure instead of methoxy group increases the PCE.
