Solar grade silicon: Technology status and industrial trends
Crystalline silicon remains (all variants included) the dominant technology to manufacture solar cells. Currently (2012–2013) more than 90% of all solar cells produced are based on this vast group of technologies. The availability, the cost and the quality to the silicon feedstock is therefore a strategic issue of paramount importance for the entire photovoltaic
