Copper Selenide powder is a fine powder composed of copper and selenium, usually black in colour, with semiconductor and other properties, fine and uniform particles, with potential applications in thermoelectric, photovoltaic, etc. It needs to be stored properly under dry and sealed conditions to prevent oxidation and other reactions.
VIMATERIAL supplies a wide range of Copper Selenide powders with high purity, we are a professional supplier of inorganic chemical raw materials, we have a professional technical team, perfect after-sales team, if you have any questions in this regard, please contact us.
Molecular Formula: Cu₂Se
Molecular weight: 206.05
Appearance: usually dark blue or black powder.
Density: about 6.84 g/cm³.
Crystal Structure: Forms orthorhombic crystals under low pressure and cubic crystals under high pressure.
Photovoltaic field: It can be used in the preparation of CIGS thin film solar cells, which can convert sunlight into electricity.
Photodetection: Cu₂Se-based photodetectors can be used to detect infrared and near-infrared light, and are useful in communications, environmental monitoring and scientific research.
Thermal Imaging: The development of thermal imaging cameras and sensors capable of visualising the thermal distribution and temperature difference in a variety of applications, such as security and industrial inspection.
Nuclear Radiation Detection: Cu₂Se-based detectors are used in gamma-ray spectrometers and radiation detectors for nuclear physics research, nuclear medicine and radiation monitoring.
Each batch of products implement the strictest quality control system, we have completed product records, product traceability with strict quality assurance. We have a complete process for the handling of non-conforming products, and will not flow the non-conforming products to the next process. We provide samples for customers’ re-inspection, and we also support the third party inspection organisations designated by customers.
Copper Selenide powders are packed in double vacuum bags or double vacuum bottles with a minimum packaging unit of 100g/bottle.
Copper Selenide powders should be stored in a dry, cool, well-ventilated environment, protected from light. Sealed containers should preferably be filled with an inert gas, e.g. argon, to prevent moisture, oxidation and contamination by impurities, and should be isolated from strong oxidising agents, acids and other substances with which chemical reactions may occur.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
