Copper Indium Sulfide is a compound of copper, indium and sulphur, often black or dark grey in appearance, with semiconducting properties and promising applications in the field of photovoltaic conversion.
VImaterial has a professional technical team, and our production process can precisely control the ratio of copper, indium and sulphur in Copper Indium Sulfide granules, to ensure the high purity and stability of the product. We are able to customise the particle size and shape of the pellets to suit your needs, so please contact us if you have any questions.
Molecular formula CuInS₂.
Molecular weight is about 242.5 g/mol.
Appearance: Usually black or grey-black powdery solid.
Density: about 4.7-5.3 g/cm³.
Melting point: about 1050°C.
Crystal structure: Tetragonal crystal structure
Solar cell field: It can be used as the absorber layer material for the preparation of solar cells, with suitable forbidden band width and high light absorption coefficient, it can effectively absorb the sunlight and convert it into electricity to improve the photoelectric conversion efficiency of solar cells.
Photodetector field: with good photoelectric properties, responding to light in the visible to near-infrared region, they can be used to prepare photodetectors for the detection and conversion of optical signals.
Biomedical: It has applications in the biomedical field, such as the detection of biomolecules, chemicals and pathogens, as well as in cancer therapy and drug delivery based on its photothermal properties.
Each batch of products will be inspected, our production process has a strict quality control system, from raw materials to the final inspection, each production link has self-inspection and re-inspection, and IPQC inspection. We also provide samples for customers to re-inspection, if the customer has a designated inspection organisation, we also support third party inspection and issue inspection reports.
Copper Indium Sulfide pellets are usually packed in double vacuum bags or vacuum bottles. Copper Indium Sulfide pellets should be stored in a dry, cool, well-ventilated environment in sealed containers, protected from moisture, light, heat and corrosive substances to prevent oxidation, deliquescence or changes in chemical structure and to ensure the stability of the pellets. This prevents oxidation, deliquescence or changes in the chemical structure of the pellets and ensures the stability of 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.
