Counting Experiments with Perovskites

(A) Combinations found at each stage of the screening procedure.

(B) Perovskite compounds with an HHI_R lower than CdTe (3,296) for each anion.

(C) The distribution of hexagonal, cubic, and orthorhombic perovskite structures predicted on the basis of the Goldschmidt tolerance factor and Shannon radii of the ions.

(D) ABC₃ combinations found in the Materials Project database. They are sorted into structure type according to space group (here, orthorhombic and lower-symmetry perovskites are grouped together).
