The synergistic effect of fluorination on molecular energy level modulation is realized by introducing fluorine atoms onto both the donor and the acceptor moieties in a D-A polymer, and as a result, the polymer solar cell device based on the trifluorinated polymer, PBT-3F, shows a high efficiency of 8.6%, under illumination of AM 1.5G, 100 mW cm(-) (2) .
通过在 D-A 聚合物的给体和受体部分都引入氟原子，实现了氟化对分子能级调节的协同效应，因此，基于三氟聚合物 PBT-3F 的聚合物太阳能电池器件在 AM 1.5G、100 mW cm(-2) 的光照下表现出 8.6%的高效率。
