摘要：
Zinc oxide nanorod arrays (ZnO NRAs) have been previously introduced as electron transport layer (ETL) of perovskite solar cells (PSCs) due to their high electron mobility and unique textured morphology. However, the presence of hydroxyl and oxygen vacancies on the surface of bare intrinsic ZnO NRAs may act as defect centers leading to carrier nonradiative recombination and the device photovoltaic performance degradation. Here, we propose a mutilayer SnO2/Al-doped ZnO nanorod arrays/SnO2 (SnO2/AZO NRAs/SnO2) composite to be utilized as ETL of all-inorganic CsPbBr3 PSCs. The influence of AZO NR...
