Progress in Preparation of Electron Transport Layer in Perovskite Solar Cell

Abstract:

Electron transport layer (ETL) plays an important role in improving the performance and stability of perovskite solar cells (PSCs). SnO₂ is a good semiconductor material with high electromigration and wide band gap. TiO₂ has the advantages of superior position of conducting band (CB), long electronic life and low preparation cost, so SnO₂ and TiO₂ are often used in ETL of PSCs. In this paper, the preparation progress of SnO₂, TiO₂ and SnO₂/TiO₂ composite ETL is reviewed.
