Record 1 2008-08-25

English

Subject field(s)
  • Semiconductors (Electronics)
  • Photoelectricity and Electron Optics
  • Solar Energy
DEF

A tandem cell that rests on two thin-film semiconductor materials :microcrystalline and amorphous silicon(a-Si : H and µc-Si : H).

OBS

Both materials are bound together in thin-film tandem cells in a top layer (around 0.3 µm thick) and a lower layer (about 1.5 µm thick).

Record 2 2008-08-22

English

Subject field(s)
  • Chemistry
  • Surface Treatment of Metals
  • Semiconductors (Electronics)
DEF

A form of thin film silicon with very small (0.5-2 micron) grain structure intermixed with amorphous silicon.

CONT

Microcrystalline silicon... consists of crystalline grains that are embedded in an amorphous material. This means that microcrystalline silicon has optical characteristics like crystalline wafer material, but can be applied to any surface, for example via plasma deposition.

OBS

It is usually deposited in a thin layer (typically 1-3 microns) for tandem (stacked) thin film solar cells.

French

Domaine(s)
  • Chimie
  • Traitements de surface des métaux
  • Semi-conducteurs (Électronique)
DEF

[Matériau obtenu] en introduisant une forte proportion d'hydrogène gazeux dans le plasma de silane destiné à produire du silicium amorphe [ce qui crée] dans le matériau en croissance une certaine proportion de micrograins cristallisés.
