High Throughput Screening of Lead Free Perovskite like

We use high throughput density functional theory calculations to screen lead free perovskite like materials with compositions A 2 BBX 6, ABX 4, and A 3 B 2 X 9 for optoelectronic performance. We screen monovalent A and B cations from Na, K, Rb, Cs Cu, and Ag, trivalent B cations from Ga, In, and Sb, and monovalent anions from Cl, Br, and I.

Perovskite (structure)

Structure of a perovskite with general chemical formula ABX 3.The red spheres are X atoms (usually oxygens), the blue spheres are B atoms (a smaller metal cation, such as Ti 4+), and the green spheres are the A atoms (a larger metal cation, such as Ca 2+).Pictured is the undistorted cubic structure; the symmetry is lowered to orthorhombic, tetragonal or trigonal in many perovskites.
