Abstract: 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 TiO2, ZnO and SnO2) 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.

Key words: perovskite solar cell, photoelectric conversion efficiency, electron transport layer, organic-inorganic hybrid, interface modification
