· JVASP-12524· InSn2I5

InSn2I5 is an inorganic halide perovskite ceramic composed of indium, tin, and iodine, representing an emerging class of materials in solid-state optoelectronics research. This compound is investigated primarily for next-generation photovoltaic and semiconducting device applications, particularly as a lead-free alternative to traditional halide perovskites, offering potential advantages in stability and toxicity reduction. The material is currently at the research and development stage rather than established in high-volume industrial production, with active interest from the photovoltaic and quantum materials communities exploring its ion-transport and light-absorption properties.
