BiS3

Bismuth trisulfide (BiS₃) is an inorganic ceramic compound belonging to the chalcogenide family, composed of bismuth and sulfur elements. While primarily of research interest rather than established commercial production, BiS₃ represents a candidate material for thermoelectric and optoelectronic applications due to its layered crystal structure and semiconducting properties. The material shows promise in next-generation energy conversion and photovoltaic research, where engineers explore alternatives to more toxic or scarce compounds in high-temperature power generation and light-harvesting devices.
