Six metal-free organic dyes having thiophene (1), benzene-thiophene (2), thiophene-benzene (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 (IPCE), highest short circuit photocurrent density ($J_{SC},;9.33;mA^2/cm^2$), and highest overall conversion efficiency ($eta$, 3.91%).
