Why are silicon wafers round and not square

Once the silicon has been purified, it must grow into a monocrystalline structure (ingots) of the silicon wafer. This causes the heated filament to grow slowly and then ultra-pure silicon rods are deposited, which lead to silicon of electronic quality.

Solidification of Silicon for Solar Cells

Silicon is the dominating material in solar cells. Monocrystalline and multicrystalline cells have approximately equal market shares and are produced from wafers, cut from single crystals produced by Czochralski (CZ) pulling or from polycrystalline ingots made by directional solidification, respectively. The present paper reviews how demands for lower cost, better yield, higher efficiency and
