Making Cheaper Silicon for Photovoltaics: Siemens Process vs

网页2018年6月27日In most cases, the silicon used for solar cells is derived from metallurgical grade silicon. This metallurgical grade silicon is produced by reducing silica from quartz sand with carbon: SiO2(l)+2C(s)=Si(l)+2CO(g). Next, carbon electrodes are often used in a furnace to create temperatures of around 2000°C, so that many impurities become volatile.
