摘　　要：有机-无机杂化钙钛矿型太阳能电池(简称钙钛矿太阳能电池)的最高光电转换效率已经达到25.5%,是最有希望取代硅基太阳能电池并实现广泛应用的太阳能电池之一。作为钙钛矿太阳能电池的基本组成部分,电子传输层对电池的性能起着至关重要的作用。本文阐述了钙钛矿太阳能电池中电子传输层的种类、尺寸以及界面修饰等对器件性能的影响,为继续提升钙钛矿太阳能电池性能提供参考。The highest photoelectric conversion efficiency of organic-inorganic hybrid perovskite solar cells(referred to as perovskite solar cells)has reached 25.5%,and it is one of the most promising solar cells to replace silicon-based solar cells and achieve a wide range of applications.As the basic component of the perovskite solar cell,the electron transport layer plays a vital role in the performance of the cell.This article briefly describes the effects of type(organic polymer materials and metal oxides such as TiO 2,ZnO and SnO 2)of electron transport layers in perovskite solar cells,size(the length and diameter of the nanowires,the thickness of the thin films)and interface modification on the performance of the devices.This can provide a reference for the works of continuing to improve the performance of perovskite solar cells.
