A carbazole-based conjugated polymer bearing ruthenium complexes Pbpy(Ru)-Cz was synthesized aiming to obtain a material with dual functionalities of both light absorption and hole-transport for photovoltaic cells. Chemical structures of the monomers and polymers were confirmed by ¹H NMR, IR, and elemental analysis. Pbpy(Ru)-Cz showed good thermal stability and solubility. The absorption spectrum of Pbpy(Ru)-Cz showed a broader peak covering the wavelength range from 380 to 650 nm. Preliminary photovoltaic behavior was evaluated by fabricating photovoltaic cells. As measured under a 55 mW cm‾² compact white arc lamp, Voc, Jsc, FF and ηe of the device ITO/Pbpy(Ru)-Cz:PCBM/Al were 0.18 V, 0.019 mA cm‾², 0.22 and 1.40×10‾³%, pectively.
