Because of its low cost, ease of fabrication and flexibility, a-Si has become a popular material for thAmorphous silicon (a-Si) is a non-crystalline form of silicon, commonly used as a thin-film material for photovoltaic (PV) cells in solar panels. It's called "amorphous" because the silicon atoms are arranged randomly, rather than in a structured, repeating pattern.
When light strikes an a-Si solar cell, photons are absorbed into the silicon material, exciting electrons and creating a flow of electrical current. This electrical current can then be harnessed to generate electricity.
A-Si is preferred for solar cells because it can be deposited as a thin film on a variety of substrates, such as glass or metal, and is relatively cheap to produce. However, it has lower efficiency compared to crystalline silicon solar cells.e production of thin-film solar cells.
