Antimony selenide (Sb₂Se₃) is a layered chalcogenide semiconductor compound with a narrow bandgap, belonging to the V-VI semiconductor family. It is primarily investigated for photovoltaic applications, particularly as an absorber layer in thin-film solar cells where its one-dimensional crystal structure and favorable optical properties offer advantages over conventional silicon or CdTe-based devices. Sb₂Se₃ is also explored in thermoelectric energy conversion and infrared optics, making it notable for next-generation renewable energy and sensing systems where cost-effective, non-toxic alternatives to lead-halide perovskites or other heavy-metal semiconductors are sought.
