Although the carbon dioxide and molten silicon that result from the process yield silicon that only has 1% impurity, it still isn''t pure enough for solar cell production. To purify the silicon, manufacturers use the float zone technique by allowing a rod of impure silicon to pass through a heated zone a couple of times in the same direction.

Wafer slicing, also called "wafering", is a key part of the solar photovoltaic (PV) cell manufacturing process. The wafering process begins with solid ingots made of single-crystal or multi-crystalline silicon material. Wire saws shape the ingots into squared blocks which dimensions are about 150 cm×150 cm×60 cm (Fig. 3).
