## Description

- description: The progress of tin-based halide perovskite solar cells (Sn-HaPSCs)
    is obstructed by their poor stability arising from tin oxidation. Herein, we introduced
    phenethylammonium thiocyanate (PEASCN) as a pseudohalide functional additive into
    an FASnI3 perovskite film to improve the optoelectronic properties. This approach
    is found to be effective for the suppression of Sn oxidation and the formation
    of a compact and larger grain film with a higher degree of crystallinity. The
    device with the PEASCN additive improved the device efficiency from 4.52% (for
    pristine Sn-HaP) to 9.65% with a significant increase of VOC from ∼0.411 to 0.667
    V and superior device stability. The device analysis revealed that the PEASCN
    additive has improved the optoelectronic properties coupled with a higher diffusion
    potential and suppression of bulk and interface defects in the Sn-HaPSC. This
    work corroborates that the incorporation of a pseudohalide-based functional additive
    in FASnI3 is propitious for better film formation, passivation of detrimental
    surface chemistry, and defects at the interface and in the bulk.
