摘　　要：研究了电子聚合物MEH PPV及其与金属喹啉配合物BAlq共混薄膜的光伏特性。测试结果表明:(1)共混膜中MEH PPV与BAlq发生了纳米级的相分离并形成互相渗透的结构,十分有利于光生激子离解为空穴和电子的过程及载流子在薄膜内的输运;(2)共混后的聚合物光伏器件的短路电流比共混前提高了200余倍。The photovoltaic properties of electronic polymer MEH-PPV [poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene)] film and blend film of MEH-PPV and metal-quinolinolato complex BAlq [bis(2-methyl-8-quinolinolato) (para-phenylphenolato) aluminum (III)] have been investigated in this paper. The determined results show: (1) the phase separation and phase interpenetration with nanometer scale occur in blend film of MEH-PPV and BAlq, which was very favor to the process that photogenerated excitons dissociate to holes and electrons and carriers transport in film; (2) the Isc in blend photovoltaic device ITO/MEH-PPV:BAlq/Al was two-hundred-fold larger than that in ITO/MEH-PPV/Al's.
