perowskitmaterialien

Perowskitmaterialien are a class of compounds that share the same crystal structure as the mineral calcium titanate (CaTiO3), which was first discovered in the Ural Mountains by Gustav Rose in 1837 and named after Russian mineralogist L.A. Perovski. The general chemical formula for a perowskite compound is ABX3, where 'A' and 'B' are cations of different sizes and 'X' is an anion, typically a halide or oxide. The specific arrangement of these ions in the crystal lattice gives perowskites their unique properties.

These materials exhibit a wide range of fascinating properties, including excellent light absorption, efficient charge transport, and semiconducting behavior. These characteristics make them highly attractive for various technological applications. One of the most significant areas of research and development for perowskites is in the field of solar cells, where they have demonstrated remarkable power conversion efficiencies in a relatively short period. Their ability to be processed from solution at low temperatures also offers the potential for low-cost and flexible solar panel manufacturing.

Beyond solar energy, perowskitmaterialien are being explored for use in light-emitting diodes (LEDs), photodetectors, lasers, and even thermoelectric devices. Their tunability, meaning their properties can be modified by altering their chemical composition, further enhances their versatility and potential for innovation. However, challenges such as long-term stability and the presence of lead in some highly efficient formulations are active areas of ongoing research.
