摘要

An amine-terminated hyperbranched poly(aryl-ether-urea) (HBPEU) was prepared from an AB2-type blocked isocyanate monomer and then its end groups were modified into urea (M-HBPEU) by reaction with phenyl isocyanate. Both of the polymers were doped with N3-dye along with KI/I_2 to work as efficient polymer electrolytes in nanocrystalline dye sensitized solar cell. The increment in the conductivity of doped HBPEU and doped M-HBPEU was very significant and reached its value at 8.2 × 10~(-3) and 4.1 × 10~(-2) S/cm, respectively. The current-voltage (I-V) characteristics of these two doped polymers measured under simulated sunlight with AM 1.5 at 60 mW/cm~2 generate photocurrent of 2.5 and 3.6 mA/cm~2, together with a photo voltage of 690 and 750 mV, and fill factor of 0.55 and 0.61 yielding a overall energy conversion efficiency of 2.4% and 4.1%, respectively. These results suggest that M-HBPEU show better cell performance and conductance properties than the HBPEU.
