Perovskites exhibit a common structure known as ABX 3, wherein ''A'' and ''B'' represent cations of differing sizes, and ''X'' represents an anion that forms bonds with both cations. The crystal structure of ABX 3 perovskite is depicted in Fig. 1, showcasing the arrangement and configuration of the A, B, and X atoms within the perovskite lattice.
The crystal structure of perovskites refers to the arrangement of atoms in a compound with a general formula of ABX3 or ABO3, where A and B are cations and X is an anion. It is characterized by a classic cubic structure, with A representing monovalent cations, B representing divalent metal elements, and X representing halide or mixed halide anions.
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+).
This fact was confirmed in more detail when Jeffrey A. Christians et al. showed that altering the crystal structure has a significant impact on the cell's stability and the existence of constituent layers around the perovskite layer.
Perovskite is a calcium titanium oxide mineral composed of calcium titanate, with the chemical formula CaTiO3. The mineral was named after the Russian mineralogist Lev Perovski. Compounds which have the same type of crystal structure as CaTiO 3, i.e., ABX 3 are called perovskites.
The inorganic perovskite system can be further classified into intrinsic and doped perovskite system. The power conversion efficiency of the intrinsic perovskite system is high when compared to other systems. Because of the high-conversion efficiency the stability of the material is very high and long lifetime of more than 72 hours.
Thermal evaporation One of the most recent approaches for fabrication of the perovskite solar cell is the vacuum thermal evaporation. It was firstly introduced by Snaith et al. where he fabricated the first vacuum-deposited film by co-evaporation of the organic and inorganic species .

Perovskite structures are adopted by many compounds that have the chemical formula ABX3. The idealized form is a cubic structure (space group Pm3m, no. 221), which is rarely encountered. The orthorhombic (e.g. space group Pnma, no. 62, or Amm2, no. 68) and tetragonal (e.g. space group I4/mcm, no. 140, or P4mm, no. 99) structures are the most common non-cubic variants.
