【摘要】 染料敏化太阳能电池是太阳能电池的重要分支,石墨烯能够显著改善基于二氧化钛颗粒的染料敏化太阳能电池的光阳极的性能,近几年吸引了材料科学和能源领域的广泛关注。在二氧化钛光阳极中加入石墨烯,能够降低复合反应、提升电子传输性能、增强光散射效率,最终提升光电转换效率。基于石墨烯加入TiO2光阳极的两种方式,即通过直接和TiO2混合,成为纳米复合物和作为界面改性剂改良界面,总结了最近使用石墨烯-二氧化钛光阳极为基础的染料敏化太阳能电池的发展情况,进而提出改善石墨烯的品质和改变光阳极的能级结构将是提高石墨烯-二氧化钛光阳极的染料敏化太阳能电池效率的重要发展方向。更多还原

【Abstract】 Dye sensitized solar cells(DSSCs)have attracted lots of interests because of their relatively low cost,high efficiency and easy in fabrication.Graphene improve the property of the dye-sensitized solar cells obviously.In particular,graphene has been incorporated into photoanode of dye-sensitized solar cells for the development of photoanode.The incorporation of graphene can induce lower recombination,increase electron transportation,enhance light scattering,and finally enhance the power conversion efficiency.The recent advances in the use of graphenein TiO2 photoanode as building material were revieed in dye-sensitized solar cells.更多还原
