Lattice stabilization and strain homogenization in Sn-Pb bottom subcells enable stable all-perovskite tandems solar cells

Abstract All-perovskite tandem solar cells (PTSCs) offer a promising approach to surpass the Shockley-Queisser (SQ) limit, driven by efficiently reducing thermalization and transmission losses. However, the efficiency and stability of the narrow-bandgap (NBG) subcells, which are essential for PTSC p...
