Novel organic dye sensitizers containing fluorenyl and biphenyl moieties for solar cells

The light-harvesting capabilities and photovoltaic performance of AFL1-AFL3 were investigated systematically through comparison of different π-bridges. The dye with a furan linker exhibited a higher open-circuit voltage (VOC) and monochromatic incident photon-to-current conversion efficiency (IPCE) compared to thiophene and benzene linkers.
