Lead iodide is an important basic raw material for perovskite photovoltaic cells, and its chemical purity has a significant impact on the preparation quality and photoelectric conversion efficiency of subsequent cell thin film materials. Therefore, it should be strictly controlled during its preparation process.

Used in the pharmaceutical industry, photography industry, and bronze plating. Lead iodide, as a major direct transition wide bandgap P-type compound semiconductor, is considered an excellent optoelectronic material. Lead iodide is also one of the important raw materials for preparing perovskite solar cells.
