Recent research in organic photovoltaic (OPV) is largely focused on developing low cost OPV materials such as graphene. However, graphene sheets (GSs) blended conjugated polymers are known to show inferior OPV characteristics as compared to fullerene adduct blended with conjugated polymer. Here, we demonstrate that graphene quantum dots blended with regioregular poly(3-hexylthiophene-2,5-diyl) or poly(2-methoxy-5-(2-ethylhexyloxy)-1,4phenylenevinylene) polymer results in a significant improvement in the OPV characteristics as compared to GSs blended conjugated polymers. This work has implications for inexpensive and efficient solar cells as well as organic light emitting diodes.
最近在有机光伏（OPV）方面的研究主要集中在开发低成本的 OPV 材料，例如石墨烯。然而，与富勒烯加合物与共轭聚合物混合相比，石墨烯片（GSs）与共轭聚合物混合显示出较差的 OPV 特性。在这里，我们证明了与 GSs 混合的共轭聚合物相比，与规正聚（3-己基噻吩-2,5-二基）或聚（2-甲氧基-5-（2-乙基己氧基）-1,4-亚苯基乙烯基）聚合物混合的石墨烯量子点会导致 OPV 特性的显著改善。这项工作对于廉价高效的太阳能电池以及有机发光二极管具有重要意义。
