· Ba3Ta2Se9

Ba₃Ta₂Se₉ is a ternary chalcogenide semiconductor compound composed of barium, tantalum, and selenium, belonging to the family of layered metal chalcogenides. This is primarily a research material studied for its potential in optoelectronic and photovoltaic applications, where its layered crystal structure and direct bandgap characteristics are of scientific interest. The compound represents an emerging class of materials being investigated for next-generation solar cells, photodetectors, and non-linear optical devices, though it remains largely in experimental development rather than widespread industrial production.
