Describing a material that consists of a single crystal structure, which means it has a uniform and continuous arrangement of atoms throughout.
The solar panels are made from monocrystalline silicon, which is known for its high efficiency.
Monocrystalline → It is formed from "mono-" (meaning one) and "crystallinus" (from Greek "kristallos", meaning frozen or ice). The word describes a material made up of a single crystal structure, hence 'one crystal'.
Think of 'mono-' meaning one, and 'crystal' referring to a solid with a defined structure. This helps you remember that 'monocrystalline' refers to a material made of one single crystal.
