Preparation of conjugated polymer composite films and their application to photo-electronic conversion devices

研究了利用整齐富勒烯制备聚合物光伏器件的方法--电泳法。(1)制备并表征了基于poly(3-octylthiophene-2，5-diyl-co-3-decyloxythiophene-2，5-diyl)和整齐富勒烯C_60的光伏器件。(2)测量了沉积过程中电势的时间变化。(3)找到了一种无卤溶剂，制备了整齐富勒烯和共轭聚合物的体相异质结复合材料。

The electrophoretic deposition, which is promising method to prepare polymer photovoltaic devices utilizing neat fullerenes, was investigated.(1)Photovoltaic devices based on poly(3-octylthiophene-2,5-diyl-co-3-decyloxythiophene-2,5-diyl) and neat fullerene C_60were prepared and characterized.(2)The temporal change of the electric potential during the deposition was measured.(3)A halogen-free solvent which yielded bulk heterojunction composites with neat fullerenes and conjugated polymers was found.
