Perovskite
Physical Properties
Black: small cation (divalent: having a valency of two)
Blue: large cation (tertravalent: having a valency of four)
Red:Oxide/halaide ion
Crystal Structure: Perovskites have a crystal structure with the formula ABX3, where A and B are cations and X is an anion.
High Absorption Coefficient: Perovskites have a high absorption coefficient, meaning they can absorb a large amount of light energy
High Charge Carrier Mobility: Perovskites have a high charge carrier mobility, meaning that electrons and holes can move easily through the material

Orthorhombic shape
CCP arrangement: cubic close-packed (ccp) arrangement of atoms, the unit cell consists of four layers of atoms
High Dielectric Constant: A material with a high dielectric constant can store more electrical energy than a material with a low dielectric constant
low exciton binding energy amount of energy required to separate an excited electron and the hole it left behind. A low exciton binding energy means that it takes less energy to separate the electron and hole, and they are more likely to dissociate
