Perovskite refers to a specific type of mineral and a broader class of materials that share a similar crystal structure. Named after the Russian mineralogist Lev Perovski, these materials typically have a formula of ABX3, where "A" and "B" are cations of different sizes, and "X" is an anion. Perovskites are known for their unique properties, including high efficiency in absorbing light and conducting electricity. In recent years, perovskite materials have gained significant attention in the field of solar energy due to their potential use in solar cells. They can be produced at a lower cost compared to traditional silicon-based solar cells and have shown remarkable efficiency improvements. Researchers are exploring their applications in various technologies, including LEDs and lasers.
