摘　　要：有机-无机杂化钙钛矿材料(CH3NH3PbX3)因其具有载流子迁移率高、直接带隙结构、光电转换效率高等优异的光电性能,在太阳能电池、光电探测器、发光二极管及激光器等光电子领域具有重要应用前景。然而,有机-无机杂化钙钛矿材料的稳定性问题是现阶段限制其进一步应用的瓶颈。本文首先系统论述子外界环境因素(水氧、温度、光照等)对有机-无机杂化钙钛矿材料稳定性的影响因素与物理机制。其次,总结了目前改善及提高钙钛矿材料稳定性的主要方法和技术途径,如改进合成方法、离子掺杂、器件封装等手段。同时分析了其对基于有机-无机杂化钙钛矿材料光电探测器性能的影响。最后提出了该领域在实际应用中面临的挑战和发展策略。Organic inorganic hybrid perovskite material(CH3NH3PbX3)has been widely used in solar cells,photodetectors,light-emitting diodes and lasers due to its excellent photoelectric properties,such as high carrier mobility,direct band gap coefficient and high photoelectric conversion efficiency.However,the stability of organic-inorganic hybrid perovskite materials is a difficult problem for its practical application.In this paper,we discuss the influence of external environmental factors(water and oxygen,temperature,light,etc.)on the stability of organic-inorganic hybrid perovskite materials systemically.And the main research approaches to improve and enhance the stability of perovskite materials at this stage are summarized,such as improving synthesis methods,ion doping,device packaging and other means,and also the effect on the performance of photodetector.Finally,the challenges and development strategies of the neighborhood are proposed.
