Produciton Of Solar Panels From Silicon

Silicon solar carries a complete line of the industry s best most efficient solar panels.

Produciton of solar panels from silicon. Polysilicon is produced from metallurgical grade silicon by a chemical purification process called the siemens process. The resulting pure silicon is then doped treated with with phosphorous and boron to produce an excess of electrons and a deficiency of electrons respectively to make a. Silicon solar panels are often referred to as 1 st generation panels as the silicon solar cell technology gained ground already in the 1950s. Silicon is the main component of sand and is therefore a very common material on the surface of the planet.

Pure silicon is derived from such silicon dioxides as quartzite gravel the purest silica or crushed quartz. These cells are produced from silicon. In order to become usable forms of silicon the quartz has to be mined and heated in a furnace which in turn emits sulfur dioxide and carbon dioxide into the atmosphere. When the cylindrical ingot is sliced its circular shape is squared giving the cell a unique octagonal shape.

How silicon cells become little semiconductors by treating the polysilicon with boron and phosphorus a positive and negative charge is created. This shape distinguishes the cells from the cells made of polycrystalline silicon. The primary material used for solar cells today is silicon which is derived from quartz. Monocrystalline solar panels are made from pv cells sliced out of a silicon ingot grown from a pure single crystal of silicon.

In the case of a photovoltaic solar panel it is the use of so called photovoltaic cells which makes it possible to produce the photoelectric phenomenon. Pure crystalline silicon is a poor conductor of electricity as it is a semiconductor material at its core. Polycrystalline silicon or multicrystalline silicon also called polysilicon or poly si is a high purity polycrystalline form of silicon used as a raw material by the solar photovoltaic and electronics industry. We have solar panels for homes commercial system solar panels as well as complete lines of both small solar panels and large solar panels.

This p n junction is where the electricity happens.
