Electron Transport Materials: Inorganic Electron Transport Materials in Perovskite Solar Cells (Adv. Funct. Mater. 5/2021)

In article number 2008300, Liangyou Lin, Xianbao Wang, Gregory J. Wilson, and co-workers review the state-of-the-art for inorganic electron transport materials (ETMs) in perovskite solar cells. Depicted are typical device architectures including the most prevalent inorganic ETMs (TiO2, SnO2 and ZnO) that have enabled champion single-junction devices with up to 25.2% power conversion efficiency.
