## Description

- description: 'Sn-based perovskites are considered a suitable alternative to toxic
    Pb-based perovskites due to their low toxicity and optimum optoelectronic properties.
    However, high-efficiency Sn-based perovskite solar cells (PSCs) typically use
    poly (3,4-ethylenedioxythiophene): polystyrene sulfonic acid (PEDOT:PSS) as a
    hole transport material (HTM), which limits their stability due to its acidic
    nature. This study introduces SnOX nanocrystals, synthesized through a synproportionation
    reaction of Sn4+ with Sn0 under mild conditions, as a replacement for PEDOT:PSS.
    X-ray photoelectron and ultraviolet photoelectron spectroscopy analyses revealed
    that the Sn0 reduces Sn4+ by 38% and elevates the highest occupied molecular orbital
    (HOMO) to –5.70 eV, close to PEDOT:PSS, enabling HTM behavior. The perovskite
    films on SnOX exhibit improved grain size and crystallinity compared to PEDOT:PSS.
    The resulting SnOX-based Sn-PSCs achieved a power conversion efficiency of 11.11%.
    They retained 90% of their efficiency after 1000 h of maximum power point tracking,
    indicating superior stability over PEDOT:PSS-based devices.'
