The team's search for the new material, described in the journal ACS Nano, centered on nano-sized particles of titanium dioxide, which were coated with either cadmium sulfide or cadmium selenide
Metier IR and Broadband Optics are fabricated to specification from calcium fluoride, magnesium fluoride, germanium, silicon, zinc selenide
and zinc sulfide.
Washington, Feb 26 (ANI): A team of scientists has developed the very first optical fiber made with a core of zinc selenide
- a light-yellow compound that can be used as a semiconductor.
The solar R&D center will continue to develop the copper indium gallium selenide
(CIGS) thin-film technology licensed from Stion of the United States in June this year.
The hexane layer of the samples was removed, dried under a nitrogen stream environment, re-dissolved in chloroform and deposited onto a temperature-controlled zinc selenide
crystal coupled to an infrared spectrometer.
The dots, from 2 to 10 nanometers (nm) across, are typically made of cadmium selenide
or lead sulfide.
This translates into a throughput of 1 module/min, faster than current thin-film plate technology; 2) The deposition is extremely uniform; both in terms of layer thickness across the module and in terms of microstructure; 3) Thickness of the semiconductor layers can be controlled by adjusting the feed rate of the semiconductor powder; and 4) The system may extend into different thin-film materials such as copper indium selenide
Tenders are invited for supply installation commissioning and training of 10 kwp grid connected rooftop solar photovoltaic system based on cigs copper indium gallium selenide
solar pv module
They discovered that hot electrons can be transferred from photo-excited lead selenide
nanocrystals to an electron conductor made of widely used titanium dioxide.
The optics can be fabricated from sapphire and spinel for demanding environments; germanium for detector and sensor applications; zinc selenide
and sulfide for laser and FLIR applications; calcium and magnesium fluoride for non-hygroscopic front surface applications; and from silicon for mirrors and reflectors.
For FT-IR analysis, the researchers dried the extracts on zinc selenide
crystals and scanned them in a spectrometer with a spectral range of 4000-700 [cm.
