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.
Polycrystalline sillicon (also called: polysilicon, poly crystal, poly-Si or also: multi-Si, mc-Si) are manufactured from cast square ingots, produced by cooling and solidifying molten silicon. The liquid silicon is poured into blocks which are cut into thin plates.
Polycrystalline silicon cells are used as a strategy to reduce costs by using less expensive wafers made of silicon consisting of crystalline silicon grains. The use of polycrystalline silicon cells in this context is not a reason but a cost-saving measure.
Crystalline silicon (c-Si) cells are obtained from thin slices of single crystal silicon, 160–240 μm thick, cut from a single crystal or a block. The type of crystalline cell produced depends on the silicon wafer manufacturing process. The main types of crystalline cells are: ribbon and sheet-defined film growth (ribbon/sheet c-Si).
Basic structure of crystalline silicon solar cells. The fabrication of crystalline silicon solar cells consists of three main processes, i.e., preparing a junction by diffusion, vapor deposition of an anti-reflection film, and electrode preparation).
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.
