Copper Selenide granules are solid particles composed of copper and selenium with specific physicochemical properties, commonly found in black cubic crystals and other forms, which have important applications in optoelectronics, semiconductors and other fields.
We supply Copper Selenide granules, our Copper Selenide Pellets have high thermoelectric efficiency, low price, high product stability, strict product quality control and small MOQ. We have a professional technical research and development team, you can contact us if you have any questions.
Molecular formula: Cu₂Se
Molecular weight: about 206.0520
Appearance: usually dark blue to black crystal particles
Density: 6.84 g/mL
Melting point: 1113°C
Crystal Structure: Tetragonal crystal structure, in which copper and selenium atoms form a regular crystal lattice in a specific arrangement, this structure gives copper selenide unique physical and chemical properties.
Thermoelectricity: In the field of thermoelectricity, it can be used in the manufacture of thermoelectric generators and refrigeration equipment, which can efficiently convert heat and electricity by virtue of its good thermoelectric properties.
Photovoltaic field: In solar cells, Cu₂Se, as an absorption layer material, can effectively absorb sunlight and generate carriers, which is expected to enhance the photoelectric conversion efficiency of photovoltaic cells.
Electronic devices: It can be used as a contact material in the manufacture of electronic components, such as transistors and diodes, and its electrical properties can be utilised to improve the performance of electronic devices, for example, by reducing contact resistance.
Optoelectronic device field: In the field of optoelectronic devices, it can be used to manufacture photodetectors to detect and convert light signals in a specific wavelength range, which plays a role in optical communications and other fields.
Catalysis: In catalytic reactions, especially those involving hydrogen generation or organic synthesis, Cu₂Se can be used as a catalyst to accelerate the reaction process by utilising the active sites on its surface.
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 granules are packed in double vacuum bags or double vacuum bottles with outer cartons. The minimum packaging unit is 100g/bottle.
Copper Selenide granules should be stored in a dry, cool, light-proof and well-sealed environment, preferably in containers filled with inert gas, avoiding contact with air, moisture, strong acids and strong oxidising agents, to prevent oxidation, deliquescence or chemical reactions that could alter their properties.
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.
