## Description

- description: Tin-based perovskites, characterized by their advantageous bandgap
    and much lower toxicity, have emerged as a promising alternative to lead-based
    perovskites in solar cell applications. However, the efficiency and stability
    of tin-based perovskite solar cells (Sn-PSCs) are still limited by defects resulting
    from the easy oxidation of Sn2+ to Sn4+. Herein, an approach to enhance the optoelectronic
    performance of Sn-PSCs by incorporating terpyridine-zinc(II) (ZnTPY) coordination
    nanosheets (CONASHs), synthesized via liquid–liquid interfacial polymerization,
    into tin-based perovskites is delivered. Following physical fragmentation, ZnTPY
    CONASHs, enriched with unsaturated terpyridine groups, undergo multidentate chelation
    with SnI2, forming ZnTPY:SnI2 heterogeneous nuclei. This process effectively enhances
    the crystallization of tin-based perovskites while mitigating recombination and
    defect chemistry related to Sn2+ oxidation. As a result of superior crystal quality,
    the ZnTPY CONASHs-modified tin perovskite exhibits a longer photoluminescence
    lifetime. Consequently, the Sn-PSC incorporating ZnTPY complex achieves a power
    conversion efficiency of 11.59%, compared to 9.14% for the control device, along
    with improved operational stability with encapsulation. Thus, this work underscores
    the critical role of coordination nanosheets for regulating coordination in the
    precursor solution to achieve high-quality tin-based perovskite films, offering
    a pathway to more efficient and stable Sn-PSCs.
