摘要
倒置钙钛矿太阳能电池因具有器件结构简单、迟滞效应小和制造成本低等优点,受到了研究人员越来越多的关注。电子传输层作为钙钛矿太阳能电池中的重要组成部分,其作用主要是传输电子和阻挡空穴。对电子传输层进行改性,可以有效解决其表面粗糙、能级不匹配、电子迁移率低等问题,从而提高器件的光电转换效率。本文从电子传输材料的选择、电子传输层的界面修饰、掺杂作用和改性三方面综述了电子传输层对倒置钙钛矿太阳能电池的性能的影响,并对今后倒置钙钛矿太阳能电池实现商业化做出了展望。
Inverted perovskite solar cells(PSCs)have been attracted more and more attention thanks to its simple architecture,negligible hysteresis,and low manufacturing cost.Electron transport layer is an important component of perovskite solar cells,which is facilitate with electrons transfer and blocks holes.The modification of electron transport layer can effectively improve the roughness for surface,energy level,and electron mobility,so as to improve the photoelectric conversion efficiency.In this paper,the influence of ETL on the performance of inverted perovskite solar cells is reviewed from the selection of electron transport layer materials,interface modification and doping of electron transport layer and the modification,and the commercialization of inverted perovskite solar cells in the future is prospected.
