Abstract
Ordered Vacancy Double Perovskite In article number 2300165, Bansal and co-workers achieve 5.18% efficiency in planar Cs2SnI6 single-junction solar cells, showcasing its potential as an air-stable light absorber. Contrary to expectations, Cs2SnI6 challenges the notion of low electronic dimensionality in vacancy-ordered double perovskites, displaying high dispersion in its conduction band and lower effective charge carrier masses.
