Geminate polaron-pair recombination directly to the triplet state of the small dye molecule copper(II) 1,4,8,11,15,18,22,25-octabutoxy-29H,31H- phthalocyanine (CuPC) and exciton trapping in CuPC domains, combine to reduce the internal quantum efficiency of free polaron formation in the bulk-heterojunction blends of CuPC doped with [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) as the electron acceptor.
双极化子对直接复合到小分子染料铜（II）1,4,8,11,15,18,22,25-辛氧基-29H,31H-酞菁（CuPC）的三重态和在 CuPC 域中的激子俘获，结合起来降低了掺杂[6,6]-苯基-C61-丁酸甲酯（PCBM）作为电子受体的 CuPC 体异质结混合物中自由极化子形成的内部量子效率。
