Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells

ABSTRACT Narrow‐bandgap perovskite solar cells (PSCs) are promising absorbers for tandem photovoltaics; however, their performance remains limited by interfacial recombination and instability, particularly Sn 2+ oxidation and halide‐related degradation. Although fullerene derivat...
