The promising tin perovskite solar cells (PSCs) suffer from the oxidation from Sn2+ to Sn4+, leading to a disappointed conversion efficiency far from what they deserve, along with poor stability. In this work, PEABr is employed to form an ultrathin-low-dimensional perovskite layer on the surface of FASnI3 absorber film to improve the interface of perovskite/PCBM in the inverted planar device structure of "ITO/PEDOT:PSS/perovskite/PCBM/BCP/electrode". The device efficiency has been enhanced from… Expand
