CaPbI₂ is a mixed-halide perovskite ceramic composed of calcium, lead, and iodine. This is an experimental compound currently under investigation in materials research rather than an established commercial material; it belongs to the broader family of halide perovskites being explored for optoelectronic applications. The material is of interest primarily in photovoltaic and luminescent device research, where lead-halide perovskites have shown promise due to their tunable bandgaps and efficient light absorption, though toxicity concerns and stability challenges remain active research areas compared to lead-free alternatives.
