摘要：

The introduction of poly(ether urethane) (PEUR) into polymer electrolyte based on poly(ethylene oxide), LiI and I-2, has significantly increased the ionic conductivity by nearly two orders of magnitudes. An increment of I-3(-) diffusion coefficient is also observed. All-solid-state dye-sensitized solar cells are constructed using the polymer electrolytes. It was found that PEUR incorporation has a beneficial effect on the enhancement of open circuit voltage V-OC by shifting the band edge of TiO2 to a negative value. Scanning electron microscope images indicate the perfect interfacial contact between the TiO2 electrode and the blend electrolyte.
