主　　题：spray coating SnO_(2)film ETL PSCs 

摘      要：SnO_(2) has been proven to be an effective electron transport layer(ETL)material for perovskite solar cells(PSCs)owing to its excellent electrical and optical ***,we introduce a viable spray coating method for the preparation of SnO2 ***,we employ a SnO_(2) film prepared using the spray coating method as an ETL for *** PSC based on the spray-coated SnO_(2) ETL achieves a power conversion efficiency of 17.78%,which is comparable to that of PSCs based on conventional spin-coated SnO_(2) *** large-area SnO_(2) films prepared by spray coating exhibit good repeatability for device *** study shows that SnO_(2) films prepared by spray coating can be applied as ETLs for stable and high-efficiency *** the proposed method involves low material consumption,it enables the low-cost and large-scale production of PSCs.
