Cadmium chloride (CdCl2) is an inorganic ceramic compound that exists as a white crystalline solid at room temperature. Historically used in electroplating, photoelectric devices, and as a precursor in cadmium-based semiconductor manufacturing, CdCl2 has seen declining industrial adoption due to cadmium's toxicity and regulatory restrictions in many jurisdictions. Contemporary research interest focuses on CdCl2 as a thin-film material for photovoltaic applications, particularly as an interface layer in cadmium telluride (CdTe) solar cells, where its layered crystal structure and tunability make it relevant to next-generation energy conversion systems.
