摘要
The past five years have seen the remarkable rise of a new type of hybrid perovskite solar cells(PSCs).However, there still remain challenges for PSCs towards large-scale application and commercialization.The main reasons are the instability of the perovskite film and the lack of large-scale and low-cost manufacture techniques for electron transfer layer(ETL).Tin oxide(SnO_2) has emerged as a promising candidate for ETL, however, systematic exploration of its commercialized application in PSCs is still missing.Here, we prepared SnO_2 ETL through the electron beam evaporation(e-beam) technology,realizing large-scale,low-cost and uniform manufacture which would be available for industrial deployment.A Cs-containing blended perovskite absorber layer was introduced into the PSCs to effectively enhance the ambient stability.As a result, PSCs exhibit a high efficiency of 18.2% without any interface modification, and remarkable long-term stability, which remained 97% of its initial PCE after being stored over 34 days.Our result demonstrated the great potential of the PSCs based on SnO_2 ETL towards commercially viable.
