Brown, "Interaction of aluminum with hydrogenated amorphous silicon
at low temperatures," Journal of Applied Physics, vol.
was first developed in the '70s by Stan Ovshinsky, the co-founder of Energy Conversion Devices (ECD), and it became the material of choice for charging consumer products such as watches and pocket calculators.
NanoMarkets also notes that while amorphous silicon
has been always been hampered in the market place by its low efficiency, the development of a-Si PV cells with improved efficiency will be the key to a-Si maintaining its dominant position in the TFPV marketplace.
Some are much more stable than amorphous silicon
, even working for years without protection from the elements.
The 80,000-square foot facility produces amorphous silicon
digital x-ray detector panels for use in radiography, angiography, cardiovascular imaging, and radiation oncology.
So-called "thin film cells" can be made from amorphous silicon
and other low-cost materials, and companies developing these technologies have recently become the darlings of Silicon Valley venture capitalists.
Cameras use a military grade amorphous silicon
thermal imager and hard carbon-coated lenses to satisfy field-of-view requirements.
ECD Ovonics, (NASDAQ:ENER), Rochester Hills, has announced that United Solar Ovonic, its wholly owned subsidiary, has entered into a Memorandum of Understanding with Tianjin Jinneng Investment Company (TJIC) to form a joint venture to establish a 25-megawatt (MW) thin-film triple-junction amorphous silicon
photovoltaic module manufacturing operation in Tianjin, the People's Republic of China.
Built with the latest LCD technology, this 640 x 480 resolution amorphous silicon
TFT active matrix monitor combines with a 1/2 in.
ECD Ovonics said it plans to use the net proceeds of this transaction to double the manufacturing capacity of United Solar Ovonics' triple-junction, thin-film amorphous silicon
photovoltaic products; to exercise the option to purchase for $4.55 per share the 4.37 million shares of ECD Ovonics' common stock held by TRMI Holdings, Inc., an affiliate of Chevron Texaco Corporation; and for general corporate purposes, including research and development investments.
This technology enables a direct conversion of X-ray to digital information, unlike some other detector systems, such as amorphous silicon
(aSi-CsI), which use indirect X-ray conversion.
The new displays are produced using Sharp's proprietary Amorphous silicon
and CG-Silicon manufacturing processes.
It is perhaps the largest solar array yet built using amorphous silicon
The unit's long-lasting Amorphous Silicon
Drum, as well as its high--toner and developer, yields results in a low cost per page for color and monochrome prints.
According to the company, the manufacturing equipment, designed and built by ECD, is the world's largest and most advanced for the manufacture of thin-film amorphous silicon
alloy solar cells that convert sunlight to electricity.
