研究了以聚（2-甲氧基-5-（2′-乙基己氧基）-对苯撑）乙烯（MEH-PPV）为电子给体，富勒烯吡咯烷衍生物为电子受体的双层薄膜异质结有机太阳能电池。我们合成了不同链长取代的可溶性富勒烯吡咯烷衍生物用于有机太阳能电池。由于富勒烯吡咯烷衍生物的高溶解度和足够长的链长，尽管它们是单体，但可以通过旋涂方法单独制备薄膜（约80- 90 nm）。双层器件的填充因子达到0.46，由于复合的减少，其高于聚合物/富勒烯吡咯烷衍生物共混膜的单层器件的填充因子0.37。
Organic solar cells made from bi-layer thin-film heterojunctions having poly((2-methoxy-5-(2′-ethylhexyloxy)-p-phenylene)vinylene) (MEH-PPV) as an electron donor and fulleropyrrolidine derivatives as an electron acceptor were investigated. We synthesized soluble fulleropyrrolidine derivatives substituted different chain lengths for the organic solar cell. Due to the high solubility and sufficiently long chain length of fulleropyrrolidine derivatives, though those are monomers, a thin film (about 80–90nm) could be fabricated individually by the spin-coating method. The fill factor of the bi-layer device was achieved to be 0.46, which is higher than that of the single-layer device by a polymer/fulleropyrrolidine derivative blend film of 0.37, due to the decrease of the recombination.
