Zusammenfassung:	Electrowinning methods and apparatus are suitable for producing elemental deposits of high quality, purity, and volume. Respective cathodes are used during electrowinning for bearing the elemental product, segregating impurities, dissolving morphologically undesirable material, and augmenting productivity. Silicon suitable for use in photovoltaic devices may be electrodeposited in solid form from silicon dioxide dissolved in a molten salt.
