The solar industry relies on silicon to make photovoltaic (PV) devices and solar cells. Outranked only by oxygen, silicon is the second-most abundant element in the earth's crust. But to be useful as a semiconductor material in solar cells, silicon must be refined to a purity of 99.9999%. Silicon refining processes are complex; fortunately, Verantis leads the way in environmental solutions that meet the solar market’s most demanding processing challenges.
