Gan thin film
WebLow-temperature deposited gallium nitride (GaN) thin-films have been introduced into planar perovskite solar cells (PSCs) as electron transport layers (ETLs) for the first time. Compact and amorphous n-type GaN layers were uniformly coated on fluorine-doped tin oxide (FTO) glass substrates via plasma-enhance WebAbstract. As a typical correlated metal oxide, vanadium dioxide (VO2) shows specific metal–insulator transition (MIT) properties and demonstrates great potential applications …
