摘要
基于有机金属卤化铅钙钛矿材料作为光活性层的太阳能电池(PSCs)已经获得了25.2%的认证效率,是除硅基太阳能电池外被认为最有可能实现商业化的太阳能电池之一。电子传输层是PSCs器件结构的最基本组成之一,其构成材料与光活性层的成膜质量、界面电荷的快速提取以及能级匹配等密切相关。因而,电子传输材料在PSCs的光伏性能及稳定性调控方面发挥着重要作用。本文对应用在PSCs中的金属氧化物电子传输材料进行了回顾与总结,着重强调了材料的纳米结构与制备工艺、半导体特性与分类以及掺杂与界面修饰等方面的研究进展,并对其今后的发展进行了展望。
Perovskite solar cells(PSCs)based on organic metal halide perovskite materials as photoactive layer have been obtained a certified power conversion efficiency of 25.2%and are considered to be one of the most commercially viable solar cells.In the device structure of PSCs,the electron transporting layer is one of the most basic components.The selection of the electron transporting materials is closely related to the film quality of the photoactive layer,the rapid extraction of interface charge and the matching of bandgaps.Therefore,the electron transporting materials play an important role in the regulating the photovoltaic performance and stability of PSCs.This paper reviews and summarizes the research progress of metal oxide electron transporting materials applied in PSCs,emphasizes the nanostructure and preparation process,photoelectric characteristics and classification,doping and surface modification of metal oxide electron transport materials,and looks forward to its future development.
