Oriented TiO2 nanocrystal array (TiO2-NA) shows unique electron extraction capability for perovskite solar cells (PSCs), due to its fewer grain boundaries and high crystallinity for effective charge collection. Based on the above advantages, we prepare the PSC based on TiO2-NA mesoporous film (mp-film), and chose CdO quantum dots as the modifier of TiO2-NA mp-film. The diameter of single TiO2-NA and gap of TiO2-NAs were controlled by controlling hydrothermal time. And CdO-QDs/TiO2-NA mp-film was prepared by successive ionic layer adsorption and reaction (SILAR)-sintering method as the ETL. In this work, oxidation state quantum dot CdO (CdO-QDs) as modifier was firstly used in the ETL of PSC, we gradually optimized CdO/TiO2-NA mesoporous film (mp-film) by control the hydrothermal time of TiO2-NA to improve PSC performances. Infiltration of perovskite adsorber submicrometer-thick rutile TiO2-NA mp-films with Spiro-MeOTAD yielded a strikingly high PCE of 11.94% under AM 1.5G illumination. Dependences of photovoltaic performance and interfacial electronic behavior on the length of CdO/TiO2-NA were also investigated
