A‑Site-Dependent Oxidative Stability in Tin-Lead Halide Perovskites Reveals Kinetic Origins via Gradient Oxidation Behavior
{{output}}
Tin-lead (Sn-Pb) hybrid perovskites are promising candidates for low-bandgap subcells in tandem solar cells but suffer from rapid degradation due to Sn2+ oxidation. While A-site cation composition is known to influence oxidation stability, conventional thermod... ...
