hydrogenated amorphous silicon (a-Si:H)

Hydrogenated amorphous silicon (a-Si:H) is a type of silicon material that is non-crystalline, meaning its atoms are arranged randomly rather than in a regular pattern like in traditional silicon. The "hydrogenated" part indicates it contains hydrogen atoms incorporated into its structure. This material is flexible, lightweight, and has good electronic properties, making it useful for applications like thin-film solar cells and displays. The hydrogen helps stabilize the structure, reducing defects and improving its performance. Overall, a-Si:H enables cost-effective and versatile electronic devices by providing efficient light-to-electrical energy conversion and display capabilities.
