基于宽带隙聚合物太阳能电池的研究进展

Research Progress on Wide Bandgap Polymers for Polymer Solar Cells

有机太阳能电池因为制备过程简单、重量轻、成本低廉和可制成柔性器件等优点受到了广泛的关注。近年来,随着窄带隙小分子受体材料的快速发展,与之光谱匹配的宽带隙给体聚合物太阳能电池表现出较高的PCE。研究人员通过苯并二噻吩(BDT)、苯并二噻吩-4,8-二酮(BDD)、萘并双三唑和苯并三唑(BTA)等构建块,设计合成了一系列高效的宽带隙给体聚合物。在此对宽带隙聚合物非富勒烯太阳能电池的研究进展进行综述。

Organic solar cells have attracted much attention because of their excellent advantages of easy fabrication,light-weight,low-cost and flexibility.In recent years,with the rapid development of narrow-band gap small molecular acceptor materials,the wide band gap donor polymer solar cells with spectrum matching show higher PCE.A series of high efficient wide band gap donor polymers were designed and synthesized by using benzodithiophene(BDT),benzodithiophene-4,8-dione(BDD),naphthalene bistriazole(TZNT)and benztriazole(BTA)as building blocks.The research progress onnon fullerene organic solar cells with wide gap donor polymers was reviewed.
