以共轭聚合物聚[2-甲氧基-5-（3′，7 ′-二甲基辛氧基）-1，4-亚苯基亚乙烯基]（MDMO-PPV）为给体，富勒烯分子为受体，系统研究了富勒烯侧链功能化对本体异质结聚合物：富勒烯太阳能电池的形貌和电光性能的影响.不同的侧链的富勒烯被发现诱导形态的变化，如通过不同的分析技术，如透射电子显微镜（TEM），X射线衍射（XRD），和核磁共振（NMR）证实。具有较短侧链的富勒烯，[6，6]-苯基-C61-丁酸甲酯（PCBM），在共混物中形成结晶纳米相，而对于替代的二苯基亚甲基富勒烯受体，[6，6]-1，1-双（4，4 ′-十二烷氧基苯基）亚甲基富勒烯（β-12），情况并非如此。核磁共振的引入使我们能够估计晶体的分数。
The influence of fullerene side chain functionalization on both the morphology and electro-optical properties of bulk-heterojunction polymer:fullerene solar cells is discussed through a systematic investigation of material blends consisting of the conjugated polymer poly[2-methoxy-5-(3′,7′-dimethyloctyloxy)-1,4-phenylene vinylene] (MDMO-PPV) as donor and fullerene molecules with different side chains as the acceptor. The varying side chain of the fullerenes was found to induce morphological changes as confirmed by different analytical techniques such as Transmission Electron Microscopy (TEM), X-ray Diffraction (XRD), and Nuclear Magnetic Resonance (NMR). The fullerene with the shorter side chain, [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), forms crystalline nanophases in the blend, while this is not the case for the alternative diphenylmethanofullerene acceptor, [6,6]-1,1-bis(4,4′-dodecyloxyphenyl)methanofullerene (DPM-12). The introduction of NMR allows us to estimate the fraction of crystalline f...
