ABX3PerowskitVerbindungen

ABX3PerowskitV refers to a class of crystalline materials with the general chemical formula ABX3. In this specific notation, 'A' and 'B' typically represent cations, and 'X' represents an anion, often a halide or oxide. The 'v' at the end might denote a specific variation or a particular research focus, such as a specific element substituted at one of the sites or a focus on optoelectronic properties. These materials crystallize in a structure analogous to the mineral perovskite, characterized by a three-dimensional network of corner-sharing BX6 octahedra with the larger A-site cation residing in the interstitial space.

Perovskite-type structures are highly versatile and have garnered significant attention due to their diverse applications. The specific properties of an ABX3PerowskitV material are heavily dependent on the chemical identities of the A, B, and X elements. By tuning these elements, researchers can modify properties such as bandgap, charge carrier mobility, and stability. This tunability makes them promising candidates for various technological advancements.

Key areas of research for ABX3PerowskitV materials include their use in solar cells, where they have achieved remarkable efficiencies as light-absorbing layers. Their excellent semiconducting properties also make them suitable for light-emitting diodes (LEDs), photodetectors, and other optoelectronic devices. Furthermore, some perovskites exhibit ferroelectric and piezoelectric properties, opening doors for applications in sensors and actuators. Ongoing research aims to enhance the stability and scalability of these materials for widespread commercial adoption.
