perovszkit

Perovskite refers to a mineral with a specific crystal structure, calcium titanate (CaTiO3). However, the term is widely used in materials science to describe any compound that shares this particular atomic arrangement. This structure is characterized by three different elements arranged in a cubic or pseudo-cubic lattice. Specifically, a larger cation sits at the corners of the cube, a smaller cation occupies the central body position, and anions fill the positions between them.

This unique structure allows for a wide range of chemical compositions, leading to materials with diverse properties. Many different elements can substitute for calcium, titanium, and oxygen in the perovskite structure, creating a vast family of compounds. These materials are known for their interesting optical, electrical, magnetic, and catalytic properties.

Perovskite materials have garnered significant attention for their potential applications in various fields. One of the most prominent areas is solar energy. Perovskite solar cells have demonstrated remarkable efficiency improvements in recent years, rivaling and sometimes surpassing traditional silicon-based solar cells, while offering the potential for lower manufacturing costs and flexibility. Other applications include light-emitting diodes (LEDs), photodetectors, thermoelectric devices, and catalysts. The tunability of their properties through chemical modification makes them a versatile platform for technological innovation.
