Amorphous silicon is a non-crystalline form of silicon that lacks a long-range order in its atomic structure. Unlike crystalline silicon, which has a regular arrangement of atoms, amorphous silicon has a more random configuration. This property makes it useful in various applications, particularly in thin-film solar cells and electronic devices. One of the key advantages of amorphous silicon is its ability to be deposited on flexible substrates, allowing for lightweight and versatile designs. It is also less expensive to produce than crystalline silicon, making it an attractive option for manufacturers looking to reduce costs while maintaining efficiency in solar energy conversion.
