· Rb4 Co2 I8

Rb4Co2I8 is a halide perovskite semiconductor compound combining rubidium, cobalt, and iodine in a crystalline structure. This is a research-stage material being studied for its semiconducting and optoelectronic properties, belonging to the broader family of metal halide perovskites that show promise for next-generation photovoltaic and light-emission applications. The specific incorporation of cobalt and rubidium distinguishes it from more commonly investigated lead or tin-based perovskites, potentially offering different band gap tuning and stability characteristics relevant to emerging solid-state device architectures.
