  We developed a high-throughput screening scheme to acquire candidate coating
materials for hybrid perovskites. From more than 1.8 million entries of an
inorganic compound database, we collected 93 binary and ternary materials with
promising properties for protectively coating halide-perovskite photoabsorbers
in perovskite solar cells. These candidates fulfill a series of criteria,
including wide band gaps, abundant and non-toxic elements, water-insoluble, and
small lattice mismatch with surface models of halide perovskites.
