English

Subject field(s)
  • Semiconductors (Electronics)
  • Solar Energy
DEF

Silicon which has solidified at such a rate that many small crystals (crystallites) were formed.

CONT

The product, called "polycrystalline silicon" (polysilicon or poly) is granular in nature, and the size of the crystallites depends on the conditions under which the silicon cooled. ... Polysilicon can be formed as an ingot, or solid block, or in the shape of a ribbon drawn up from a molten bath, or by boiling the silicon off and allowing the vapor to deposit and cool on some flat surface.

OBS

A polycrystalline material is a semiconductor material, deposited by vacuum evaporation or another suitable method, consisting of a multitude of tiny crystals with random orientation, used as the active region of thin-film transistors.

  • Énergie solaire
CONT

Silicium polycristallin. Les efforts en vue de la fabrication d'un semiconducteur à faible prix de revient ont orienté tout naturellement les études vers le silicium sous forme de polycristal. On équipe maintenant les systèmes photovoltaïques terrestres de cellules solaires fabriquées avec ce matériau.
