Ca2 H2 I2

Calcium iodide hydride (Ca₂H₂I₂) is an experimental semiconductor compound belonging to the class of halide-hydride materials, combining calcium, iodine, and hydrogen in a crystalline structure. This material is primarily of research interest for optoelectronic and photovoltaic applications, as halide semiconductors have shown promise for next-generation solar cells and light-emitting devices. Its notable advantage over traditional semiconductors lies in the potential for low-cost synthesis and tunability of electronic properties through compositional variation, though industrial adoption remains limited due to stability and scalability challenges.
