| 中文摘要 | the surface composition of poly(3-hexylthiophene-2,5-diyl) and fullerene derivative [6,6]-phenyl-c61-butyric acid methyl ester (p3ht/pcbm) blend films could be changed by controlling the film formation process via using mixed solvents with different evaporation rates. the second solvent, with a higher boiling point than that of the first solvent and much better solubility for pcbm than p3ht, is chosen to mix with the first solvent with a lower boiling point and good solubility for both pcbm and p3ht. the slow evaporation rate of the second solvent provides enough time for pcbm to diffuse upwards during the solvent evaporation. thus, the weight ratio of pcbm and p3ht (m (pcbm)/m (p3ht)) at surface of the blend films was varied from ca. 0.1 to ca. 0.72, i.e., it increases about seven times by changing from single solvent to mixed solvents. meanwhile, the mixed solvents were in favor to form p3ht naonofiber network and enhance phase separation of p3ht/pcbm blend films. as a result, the power conversion efficiency of the device from mixed solvents with slow evaporation process was about 1.5 times of the one from single solvents. |
