TiO2 is most commonly employed as an electron transport layer (ETL) in mesoscopic n–i–p perovskite solar cells (PSCs). However, the low electron mobility, low electrical conductivity, and high electronic trap states of TiO2 may have negative impacts on further enhancement of PSC performance. Metal d...
