摘要

We have witnessed unprecedented progress of per-ovskite solar cells(PSCs)in last few years.The power conver-sion efficiency(PCE)has been boosted from 3.8％to the cur-rent record of 25.5％[1,2].A typical PSC consists of a polycrystal-line perovskite layer sandwiched between electron-transport-ing layers(ETLs)and hole-transporting layers(HTLs),with two configurations:regular(n-i-p)and inverted(p-i-n).Till now,the record efficiency of PSCs is still dominated by devices with the regular structure,which exploits inorganic electron-transport materials(ETMs)due to their low cost and chemic-al stability.This article overviews the latest progress of inorgan-ic ETMs in regular PSCs,the interface treatments and other op-timization strategies for high PCE and stability.
