List Of Silicon Producers
This is a list of silicon producers. The industry involves several very different stages of production. Production starts at silicon metal, which is the material used to gain high purity silicon. High purity silicon in different grades of purity is used for growing silicon ingots, which are sliced to wafers in a process called wafering. Compositionally pure polycrystalline silicon wafers are useful for photovoltaics. Dislocation-free and extremely flat single-crystal silicon wafers are required in the manufacture of computer chips. Polysilicon producers Polysilicon producers: * Elkem * JFE Steel * Nitol Solar (Russia), bankrupt since 2019 * SunEdison * SolarWorld High-purity silicon Producers of high-purity silicon, an intermediate in the manufacture of polysilicon * Hemlock Semiconductor Corporation * Renewable Energy Corporation (REC) * SunEdison * Tokuyama Corporation * Wacker Chemie AG Silicon wafer manufacturers A partial list of major producers of wafers (ma ...

Silicon
Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid (sometimes considered a non-metal) and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. Silicon is a significant element that is essential for several physiological and metabolic processes in plants. Silicon is widely regarded as the predominant semiconductor material due to its versatile applications in various electrical devices such as transistors, solar cells, integrated circuits, and others. These may be due to its significant band gap, expansive optical transmission range, extensive absorption spectrum, surface roughening, and effective anti-reflection coating. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was first able to p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Photovoltaics Companies
This is a list of notable photovoltaics (PV) companies. Grid-connected solar photovoltaics (PV) is the fastest growing energy technology in the world, growing from a cumulative installed capacity of 7.7 GW in 2007, to 320 GW in 2016. In 2016, 93% of the global PV cell manufacturing capacity utilized crystalline silicon (cSi) technology, representing a commanding lead over rival forms of PV technology, such as cadmium telluride (CdTe), amorphous silicon (aSi), and copper indium gallium selenide (CIGS). In 2016, manufacturers in China and Taiwan met the majority of global PV module demand, accounting for 68% of all modules, followed by the rest of Asia at 14%. The United States and Canada manufactured 6%, and Europe manufactured a mere 4%. In 2021 China produced about 80% of the polysilicon, 95% of wafers, 80% of cells and 70% of modules. Module production capacity reached 460 GW with crystalline silicon technology assembly accounting for 98%. Photovoltaics companies include ...

Siltronic
Siltronic AG is a German manufacturer of wafers made of hyperpure silicon headquartered in Munich. History In 1953, it all began in Burghausen Germany as Wacker Chemie was already researching and developing hyperpure silicon, which lead to the first semiconductor silicon to be produced in 1958. The number of employees were increased in 1961 as they began to add products, such as monocrystals, which were also distributed internationally. In 1965, Wacker acquired Monosilicon, a silicon producer in Los Angeles, USA. The new wholly owned subsidiary company was founded in 1968 as Wacker-Chemitronic Gesellschaft für Elektronik-Grundstoffe mbH ("Wacker-Chemitronic") in Burghausen. In 1978, Wacker-Chemic built a plant in Portland, Oregon and founded the Wacker Siltronic Corporation. Workers were trained in Germany before the plants opening in 1980. In 1985, a joint venture for the production of 125 mm and 150 mm wafers began in Japan with NSC Electron Corporation. It changed its name t ...
