## Description

- description: Tin perovskite solar cells (Sn-PSCs) offer considerable potential for
    lead (Pb)-free photovoltaic applications. Unfortunately, the poor crystallinity
    and facial tendency of oxidation from Sn2+ to Sn4+ are still challenging for the
    performance of Sn-PSCs. Herein, we introduced butylphosphonic acid 4-ammonium
    chloride (4ABPACl) bifunctional additive as a crosslinker in the Sn-perovskite
    precursor solution. The morphological and structural analysis confirmed that the
    terminal group –NH3+ and –PO(OH)2 of 4ABPACl cross-linked with the iodide ions
    (I-) of the perovskite framework through hydrogen bonding and suppressed the Sn2+
    oxidation.  As a result, a pinhole-free uniform perovskite film with an extended
    lifetime of charge carriers as confirmed by scanning electron microscope and time-resolved
    photoluminescence respectively. These improvements in Sn-perovskite enhanced the
    power conversion efficiency of Sn-PSCs from 6.65 to 9.20 %. Moreover, crosslinker-modified
    PSCs showed an improvement in stability both under continuous light for encapsulated
    PSCs and in the N2 glove box for unencapsulated PSCs.
