As a promising photovoltaic technology,per-ovskite solar cells(pero-SCs)have developed rapidly over the past few years and the highest power conversion effi-ciency is beyond 25％.Nowadays,the planar structure is universally popular in pero-SCs due to the simple pro-cessing technology and low-temperature preparation.Electron transport layer(ETL)is verified to play a vital role in the device performance of planar pero-SCs.Par-ticularly,the metal oxide(MO)ETL with low-cost,superb versatility,and excellent optoelectronic properties has been widely studied.This review mainly focuses on recent developments in the use of low-temperature-processed MO ETLs for planar pero-SCs.The optical and electronic properties of widely used MO materials of TiO2,ZnO,and SnO2,as well as the optimizations of these MO ETLs are briefly introduced.The commonly used methods for depositing MO ETLs are also discussed.Then,the appli-cations of different MO ETLs on pero-SCs are reviewed.Finally,the challenge and future research of MO-based ETLs toward practical application of efficient planar pero-SCs are proposed.
