摘要
石墨烯薄膜具有低阻且在可见光谱区具有高透过率,可应用于聚合物太阳能电池透明电极。本文基于时域有限差分分析方法(FDTD),研究了石墨烯太阳能电池的反射损耗及光吸收特性,并通过在玻璃基板与石墨烯间添加氧化镍层(Ni O)进行光学减反射。理论分析表明:优化的Ni O/石墨烯透明电极结构,能够成为氧化铟锡(ITO)的良好替代电极。
Graphene films with low sheet resistance and high transparency in the visible light range are promising to be used as electrodes for polymer solar cell（PSC）. In this work, the graphene with antireflection coatings is used as anode reported for PSCs. Reflectivity loss of the polymer solar cell is analyzed from the light absorption calculation for the devices with graphene-based anode electrode by applying the finite-difference time-domain（FDTD） method. The results indicate better optical coupling efficiency for the graphene-based electrode by optimizing the structure of graphene-based anode. Therefore, the single-layer of Ni O antireflection coated graphene is recommended as a good alternative to replace ITO in OSCs.
