Perovskite refers to a specific class of materials that have a characteristic crystal structure named after the mineral perovskite (CaTiO3), which was first discovered in the Ural Mountains in Russia. The general formula for perovskite-structured materials can be expressed as ABX3, where: - A is a cation (a positively charged ion) that occupies the larger dodecahedral sites.
