      abstract     = {Sn─Pb perovskites, a most promising low bandgap
                      semiconductor for multi-junction solar cells, are often
                      limited by instability due to the susceptibility of Sn2+ to
                      oxidation. Inspired by the antioxidative properties of
                      polyphenolic compounds, we introduce the reductive phenol
                      group and strong electronegative fluorine into an organic
                      conjugated structure and design a multi-functional polymer
                      with fluorine and phenol units (PF─OH). The design of
                      PF─OH allows the effective rise in the energy barrier of
                      Sn2+ oxidation, leading to a significant enhancement in the
                      stability of Sn─Pb perovskite devices from 200 to 8000
                      h—an improvement of around 100 times. Additionally, the
                      strong binding energy between Sn2+ and the phenol in PF─OH
                      critically influences Sn─Pb perovskite's crystallization
                      and grain growth, resulting in perovskite films with fewer
                      pinholes at the buried interface and extended carrier
                      lifetimes. This enhancement not only boosts the power
                      conversion efficiency (PCE) to $23.61\%,$ but also
                      significantly improves the operational stability of the
                      devices. Ultimately, this design strategy has been proven
                      universal through the phenolization of a series of
                      molecules, marking a milestone in enhancing the stability of
                      Sn─Pb perovskites.},
