Na₂LiBiI₆ is a halide perovskite ceramic compound containing sodium, lithium, bismuth, and iodine. This is an experimental material primarily under research investigation for photovoltaic and ionic conductivity applications, representing the broader class of double and triple halide perovskites being explored as lead-free alternatives to conventional perovskite solar cells. The bismuth-based composition offers potential advantages in stability and reduced toxicity compared to lead perovskites, though it remains in the development stage without widespread commercial deployment.
