PEROVSKITE CRYSTALS
A.I. GENERATED INFORMATION FROM BRAVE SEARCH ENGINE:
Perovskite crystals are a vast family of materials defined by a specific ABX₃ crystal structure, where A and B are cations and X is an anion. While the term originally referred to the mineral calcium titanium oxide ($CaTiO_3$) discovered in 1839, it now encompasses any compound sharing this structural arrangement, including metal-halide perovskites used in modern technology.
These materials are characterized by their structural versatility, allowing various elements to substitute into the lattice to create diverse properties such as superconductivity, ferroelectricity, and high light absorption. This tunability makes them critical for advanced applications, particularly in perovskite solar cells, LEDs, and electronic devices, where they offer high efficiency and potential cost benefits over traditional materials like silicon.
