Polycrystalline silicon can also be obtained during silicon manufacturing processes. Polycrystalline cells have an efficiency that varies from 12 to 21%. These solar cells are manufactured by recycling discarded electronic components: the so-called "silicon scraps,” which are remelted to obtain a compact crystalline composition.
Thin wafers which were taken from an especially grown continuous crystal are used to form m-crystalline silicon solar PV cells. Silicon material is first melted and then poured into a mould to form p-crystalline silicon solar PV cells.
Polycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called the Siemens process.
Basic polycrystalline silicon based solar cells with a total area efficiency of app. 5% has been fabricated without the involvement of anti-reflecting coating. This is a resonable result considering that comercial high efficiency solar cells have a con-version efficiency of about 22%, as outlined in chapter 1.

The technology is non-polluting and can rather easily be implemented at sites where the power demand is needed. Based on this, a method for fabricating polycrystalline silicon solar cells is sought and a thorough examination of the mechanisms of converting solar energy into elec-trical energy is examined.

At the component level, polysilicon has long been used as the conducting gate material in MOSFET and CMOS processing technologies. For these technologies it is deposited using low-pressure chemical-vapour deposition (LPCVD) reactors at high temperatures and is usually heavily doped n-type or p-type. More recently, intrinsic and doped polysilicon is being used in large-area electronics
