perowskite

Perovskite is a mineral with the chemical formula CaTiO3, named after Russian mineralogist L. A. Perovski. It is a relatively rare mineral, found in contact metamorphic rocks and some igneous rocks. The crystal structure of perovskite is cubic, and it is known for its high refractive index and dispersion, giving it a bright, adamantine luster. While naturally occurring perovskite is not common, the term "perovskite" is also used to describe a broader class of compounds that share the same crystal structure, ABX3, where A and B are cations and X is an anion.

These synthetic perovskite materials have gained significant attention in recent years due to their diverse applications, particularly in solar cells. Perovskite solar cells have demonstrated rapidly increasing efficiencies, rivaling and sometimes exceeding those of conventional silicon-based solar cells. Their tunability, meaning their optical and electronic properties can be adjusted by changing their composition, makes them versatile for various optoelectronic devices. Other potential applications for perovskite materials include light-emitting diodes (LEDs), photodetectors, and catalysts. Research continues to focus on improving their stability and scalability for widespread commercial use.
