Abstract

Perovskite Solar Cells In article number 2202491, Tingting Shi, Hsing-Lin Wang, and co-workers report highly performing organic-free and lead-free CsSnI2.6Br0.4 perovskite based solar cells, achieved via introducing dimethyl ketoxime (DMKO) as a multifunctional additive. The chemically reducing DMKO located on the grain surface, not only mitigates Sn2+ oxidation but also passivates Sn(II) related defects, forming an in situ encapsulation of the perovskite, which results in greatly enhanced ambient stability of the corresponding device.
