hydrogenated amorphous silicon

Hydrogenated amorphous silicon (a-Si:H) is a non-crystalline form of silicon that contains hydrogen atoms. Unlike crystalline silicon with an ordered structure, a-Si:H has a random, disorganized arrangement of silicon atoms, which makes it flexible and easier to produce thin, lightweight layers. The hydrogen atoms help passivate defects in the material, improving its electronic properties. This makes a-Si:H useful in devices like solar cells and displays, where cost-effectiveness and flexibility are important. Its unique structure allows it to absorb light efficiently and be deposited on various surfaces, enabling diverse applications in renewable energy and electronics.
