    Abstract

    Tin halide perovskites are promising candidates for lead‐free perovskite solar cells due to their ideal bandgap and high charge‐carrier mobility. However, poor crystal quality and rapid degradation in ambient conditions severely limit their stability and practical applications. This study demonstrates that incorporating UiO‐66, a zirconium‐based MOF, significantly enhances the performance and stability of tin halide perovskite solar cells (TPSCs). The unique porous structure and abundant carboxylate groups of UiO‐66 improve the crystallinity and film quality of FASnI₃, reduce defect density, and prolong charge carrier lifetimes. Consequently, the power conversion efficiency (PCE) of UiO‐66‐integrated TPSCs increases from 11.43% to 12.64%, and the devices maintain over 90% of their initial PCE after 100 days in a nitrogen glovebox. These findings highlight the potential of UiO‐66 in addressing the efficiency and stability challenges of tin halide perovskites.

    <jats:title>Abstract</jats:title>
    <jats:p>In this work, we elucidated the electronic structure and thermoelectric properties of intermetallic <jats:italic>X</jats:italic>Si (<jats:italic>X</jats:italic> = Co, Rh) compounds. By combining first-principles calculations and the Boltzmann equation within electron–phonon average approximation, thermoelectric properties of <jats:italic>X</jats:italic>Si are well reproduced compared to experimental observations. We found that the considerable Seebeck coefficient and low electrical resistivity give <jats:italic>X</jats:italic>Si a large power factor, which has the potential for thermoelectric applications. We also discussed the electron mean free paths, a possible factor affecting electrical conductivity when using the nanostructuring approach to optimize the thermoelectric performance.</jats:p>
