Mining silicon to make silicon-based cells is an expensive process that emits a lot of carbon dioxide. Silicon-based panels are well established in the market, but are rapidly being replaced by more efficient thin-film technologies. In general, silicon is less cost effective, but the panels are more space efficient.
