To produce one kilogram Si suitable for manufacturing solar cells, 30 pounds are required i.e. approx. 15 kg, (precisely 13.6 kg) of pure quartz. The global demand for ultra-pure quartz is 30,000 tons annually. The annual production of quartz in Greece in recent years is about 15,000 tons.
Quartz crystals are oxide minerals with the trigonal or hexagonal system, whose cell parameters are: a = 4.916 Å, b = 4.916 Å, c = 5.405 Å. The Si-O bond angle in α-quartz is 144° and the bond length is between 0.16101 and 0.16145 nm ( Götze, 2009 ). The different types of quartz crystals are shown in Table 1.
How Solar Cells are Made. Ultimately, every solar cell begins its life as quartz sand. Also known as silica sand, quartz sand consists of at least 95% pure silicon dioxide, which is also known as silica or as SiO 2. But we don't need silica for solar cells, but silicon, which means we need to get rid of the oxygen, to leave behind pure silicon.
