摘要
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 H-1 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, V-OC, J(SC), FF and eta(e) of the device ITO/Pbpy(Ru)-Cz:PCBM/A1 were 0.18 V, 0.019 mA cm(-2), 0.22 and 1.40x10(-3)%, respectively.
