SnO 2 nanoparticles (NPs) have been widely employed as electron transport layers (ETLs) in planar n-i-p perovskite solar cells (PSCs). Perfect SnO 2 ETL/perovskite interface plays a key role in high efficiency PSCs, however, the main issues caused by the self-aggregation of the SnO 2 NPs and the...
