Bi₂S₃ (Bismuth Sulfide) pellets are used as evaporation materials in physical vapor deposition (PVD) processes to produce thin films. Bismuth sulfide is a semiconductor material with a narrow band gap, making it suitable for applications in photovoltaics, thermoelectrics, and optoelectronic devices. It is particularly valued for its use in thin-film solar cells and photodetectors.
Key Applications:
- Photovoltaics: Bi₂S₃ is used in thin-film solar cells due to its favorable band gap for light absorption, which makes it efficient in converting sunlight into electricity.
- Thermoelectrics: Bismuth sulfide is employed in thermoelectric materials that convert temperature differences into electrical voltage, useful for energy harvesting applications.
- Optoelectronic Devices: Bi₂S₃ thin films are used in photodetectors and sensors due to their strong absorption in the visible and near-infrared regions.
- Biomedical Imaging: Bi₂S₃ nanoparticles are also explored for use in biomedical imaging and cancer therapy, though this is more relevant to its nanoparticle form rather than thin films.
