· K1 Rb2 Mo1 F6

K₁Rb₂Mo₁F₆ is a mixed-halide double perovskite semiconductor compound containing potassium, rubidium, molybdenum, and fluoride ions. This is a research-stage material belonging to the halide perovskite family, which shows promise for optoelectronic and photovoltaic applications due to tunable band gaps and ionic conductivity. The incorporation of multiple alkali cations (K and Rb) represents an emerging strategy to stabilize perovskite crystal structures and enhance phase stability compared to single-cation analogues, making it relevant to next-generation photovoltaic and solid-state ionic device development.
