Six metal-free organic dyes having thiophene (1), benzene-thiophene (2). thiopliene-benzenc (3), thiophene-pyridine (4), thiophene-thiophene (5), and pyridine (6) linkers between 9,9-dimethylfluorenyl terminal group and alpha-cyanoacrylic acid anchor were synthesized. Among them, organic dye 5 showed the longest lambda(max) value (424 nm) in UV-Vis absorption spectrum, better incident monochromatic photon-to-current conversion efficiency (PCE), highest short circuit photocurrent density (J(SC) 9.33 mA(2)/Cm-2) and highest overall conversion efficiency (eta, 3.91%).
