Dendritic web technique
| Глоссарий по экологии и "зеленой" энергетике |
- A method for making sheets of polycrystalline silicon in which silicon dendrites are slowly withdrawn from a melt of silicon whereupon a web of silicon forms between the dendrites and solidifies as it rises from the melt and cools.
- A method for making sheets of polycrystalline silicon in which

Chemical vapor deposition (cvd), английский
- A method of depositing thin semiconductor films used to make certain types of photovoltaic devices. with this method, a substrate is exposed to one or more vaporized compounds, one or more of which contain desirable constituents. a chemical reaction is initiated, at or near the substrate surface, to produce the desired material that will condense on the substrate.
- A technique used to deposit thin layers of coatings on a substrate . in cvd, chemicals are vaporized and then applied to the substrate using an inert gas such as nitrogen as a carrier. cvd is used in the production of microchips, integrated circuits, sensors, and protective coatings.

Edge-defined film-fed growth (efg), английский
A method for making sheets of polycrystalline silicon for photovoltaic devices in which molten silicon is drawn upward by capillary action through a mold.
