· JVASP-136807· Pb2I

Pb₂I is an inorganic ceramic compound belonging to the lead halide family, a class of materials gaining attention in optoelectronic research. This material is primarily investigated for photovoltaic and radiation detection applications due to the electronic properties inherent to lead halide perovskites and related structures. While still largely in the research phase rather than widespread industrial production, lead halide ceramics are notable for their potential in next-generation solar cells, X-ray detectors, and gamma-ray sensing devices, offering advantages over conventional semiconductors in specific wavelength sensitivity and fabrication flexibility.
