摘要
2D有机-无机杂化钙钛矿材料是通过在3D钙钛矿材料中引入大分子有机插层而形成的,具有高度的垂直生长取向和优异的表面形貌,以及良好的湿度、光、热稳定性等优点,已在太阳能电池领域受到广泛关注。综述了近几年2D有机-无机杂化钙钛矿材料光伏性能的优化策略,详细阐述了L位有机阳离子优化、无机层层数调控、表面形貌及取向优化、2D/3D钙钛矿异质结构构建等方法对2D杂化钙钛矿材料光伏性能的影响,并对2D有机-无机杂化钙钛矿材料发展方向进行了展望。
2D organic-inorganic hybrid perovskite materials are formed by the introduction of macromolecular organic intercalation in 3D perovskite materials,which have attracted widespread attention in the field of solar cells due to its high vertical-orientation growth,excellent surface morphology,superior humidity,photo and thermal stability,etc.In this paper,the strategies for optimizing photovoltaic performance of 2D organic-inorganic hybrid perovskite materials in recent years are reviewed,and the influences of these methods such as the optimization of organic cations at L sites,the thickness of the inorganic layer,surface morphology and orientation of the films,and the construction of 2D/3D perovskite heterostructures on the performance of 2D hybrid perovskites are systematically introduced.Moreover,the prospect of 2D organic-inorganic hybrid perovskite materials is also presented.
