Silicon (Si) is a chemical element with the atomic number 14 and is the second most abundant element in the Earth's crust. Silicon crystals are essential semiconductor materials widely used in electronic and optoelectronic devices. They typically exist in single-crystal or polycrystalline forms and exhibit good electrical and thermal conductivity. The change in conductivity of silicon crystals under varying temperature and light conditions makes them ideal for manufacturing diodes, transistors, and integrated circuits. Due to their excellent physical and chemical properties, silicon is also extensively used in photovoltaic applications, such as solar cells and photodetectors.
