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.
