👉 Perovskite is a type of semiconductor material that contains a rare-earth element (usually lanthanum) and boron. It is found in nature as perovskites, which are crystals with alternating layers of perovskite materials arranged in a lattice structure. These materials can be used for various applications, including solar cells, light emitting diodes, and batteries. The term "perovskite" comes from the German word "Perovsk," meaning "to shine or
