Description :
Black powder. There are two variants: 110 ℃ below are tetragonal system structure, more than 110 ℃ for cubic crystal system structure. Density 6.749 ~ 6.84 g/cm3. Melting point 1113 ℃. Easy for nitric acid, aqua regia and strong antioxidant oxidation. The element selenium and copper direct response, or by carbon reduction methods such as selenium acid copper making.
USES :
Copper Selenide for solar energy applications is a p-type or absorber layer material.Titan produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTMtesting standards.Typical and custom packagingis available. See safety data and research below and pricing/lead time above. CIS-based photovoltaic cells (PV Cells) for solar energy are fabricated from a positively charged or p-type Copper Indium Selenide (CIS) layer underneath a negatively charged or n-type layer. The p-type layer can be partially produced by thin film physical/chemical vapor deposition of a Copper Selenide Target sold under the AE Solar Energy group. Most CIS-based PV solar cells are produced from single crystal of CIS however recent technology allows for thin film deposition of CIS using copper selenide sputtering targets.
