Electrochemical production of silicon

Abstract Silicon solar cells are crucial devices for generating renewable energy to promote the and environmental fields. Presently, high-purity silicon, which is employed in cells, manufactured commercially via Siemens process. This process based on hydrogen reduction and/or thermal decomposition of trichlorosilane gas. The electrochemical producing silicon has attracted enormous attention as an alternative existing Thus, this article reviews different scientific investigations production by classifying them principles (electrorefining, electrowinning, solid-state reduction) electrolytes (molten oxides, fluorides, chlorides, fluorides–chlorides, ionic liquids [ILs], organic solvents). features electrolytic each electrolyte, well prospects, discussed.
