What is the use of silicon powder in photovoltaic panels

At the component level, polysilicon has long been used as the conducting gate material in and processing technologies. For these technologies it is deposited using low-pressure chemical-vapour deposition () reactors at high temperatures and is usually heavily doped or . More recently, intrinsic and doped polysilicon is being used in [pdf]
