Amorphous silicon is a non-crystalline form of silicon commonly used in thin-film solar cells, display technologies, and some sensors. Unlike crystalline silicon, it lacks a long-range ordered structure, making it more flexible and easier to deposit on various substrates. In cybersecurity, amorphous silicon may be relevant in the context of hardware security, as it is sometimes used in hardware components for authentication or anti-tampering measures. However, its primary application remains in electronics and photovoltaic devices, where its lower efficiency is balanced by lower cost and greater versatility.
