The eponymous Perovskite CaTiO3 crystallizes in the Pbnm space group (No. 62) with lattice constants a = 5.39 Å, b = 5.45 Å and c = 7.65 Å. Perovskites have a nearly cubic structure with the general formula ABO3. In this structure the A-site ion, in the center of the lattice, is usually an alkaline earth or rare-earth element. B-site ions, on the corners of the lattice, are 3d, 4d, and 5d

Natural perovskites are metal oxides, and are considered to be entirely inorganic materials (i.e they do not contain any carbon-hydrogen bonds). Solar cell perovskites however contain a mixture of inorganic and organic ions, which are arranged in the same way as the classical inorganic perovskites.
In short, perovskite materials do not refer to materials made of "perovskite" in a narrow sense, but a general term for materials with a specific structure. Perovskite solar cells (PSCs) are solar cells that use perovskite structure materials as light-absorbing materials, and belong to the representative of the third generation of high-efficiency thin-film cells.
Perovskite materials exhibit excellent optoelectronic properties and superior device performance via two key device architectures—mesoscopic and planar—as illustrated in Figure 1.
