Highly synergistic dispersible graphene/sulfonated carbon nanotubes(G:SCNT)with interpenetrating conductive network structure has been coated on poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS) to fabricate PEDOT:PSS/G:SCNT transparent conductive electrode(TCE).SCNT may play an important role in not only suppressing the agglomeration and overlapping of pristine graphene,but also bridging graphene sheets to improve the interlamellar ***:PSS/G:SCNT possessing improved conductivity(2645 S·cm-1) and transmittance(5%),superior hole mobility(5.04×10-4 cm2/V·s),suitable work function(4.93 eV) and favorable morphology can not only replace indium tin oxide(ITO) as TCE to realize device efficiency achieving 5.8%with an effective area of 15mm2,but also simplify the device structure(TCE/active layer/metal electrode).Moreover,a large-scale,flexible and robust PET/PEDOT:PSS/G:SCNT electrode has been fabricated by doctor-blading *** from preferable transmittance and conductivity comparable to commercial PET/ITO,PETVPEDOT:PSS/G:SCNT exhibits excellent mechanical flexibility and durability under bending 500 cycles,which is superior to that of PET/***,this approach provides a reliable royal road for realizing the commercial production of large-scale TCE to replace ITO.

作者： yiwang chen College of Chemistry Nanchang University

The College of Chemistry, Nanchang University originated from the Department of Chemistry, Jiangxi University, which is one of the first Science and Engineering subjects of the University. After nearly 60 years' long term and great-leap-forward development, and several times' recombination, it was renamed College of Chemistry. At present, College of Chemistry owns four province level key laboratories, such as New Energy Chemistry Institute of Jiangxi Province;three non-independent university level institutes, such as Institute of Polymer Science;and two independent university level institutes: International Ordered Materials Science Institute and Institute of Polymer and Energy Chemistry. In addition, it currently provides two B. S. programs, Chemistry and Applied Chemistry. The college provides both first-level discipline Ph.D program of chemistry, and second-level discipline Ph.D program of industrial catalysis, and owns two postdoctoral research stations (chemistry and chemical engineering & technology). Moreover, the college provides a firstlevel discipline M. S. program of Chemistry and three second-level discipline M. E. programs of Applied Chemistry, Industrial Catalysis and Pharmaceutical Engineering.

选择了两种具有不同末端基的非富勒烯受体分子3,9-双-[2-甲烯基-(3-1,1-甲烯丙二腈茚酮)-5,5,11,11-四-(4-己基苯基)]-噻吩[3,2-b]并噻吩引达省二噻吩(ITIC)和3,9-双-[2-甲烯基-(3-1,1-甲烯丙二腈-6,7-一氟茚酮)-5,5,11,11-四-(4-己基苯基)]-噻吩[3,2-b]并噻吩引达省二噻吩(IT-2F)作为第三组分,通过一步沉积(O-SD)和分步顺序沉积(T-SD)两种活性层构筑工艺,分别制备了常规的本体异质结(BHJ)和优化的准平面异质结(PPHJ)三元器件.研究发现,本体异质结薄膜中第三组分相容性的差异可以用来调控薄膜相分离形貌;其中,基于IT-2F的三元薄膜活性层相分离明显增大,器件效率由二元器件的12.02%下降至9.25%;而ITIC的三元薄膜相分离形貌无明显改变,器件效率略有提升.值得注意的是,通过T-SD方法均可以获得垂直梯度分布的异质结活性层薄膜,避免了相容性差异对薄膜形貌的影响,相应的准平面异质结器件获得了超过了13%的光电效率.本文工作表明,利用相容性差异以及顺序沉积工艺来调控活性层的相分离形貌是制备高性能有机太阳电池有效策略.
