What is pbi2?

Lead iodide, also known as lead(II) iodide or PbI2, is a chemical compound composed of lead and iodine. It is a yellow solid that is insoluble in water.

Lead iodide is commonly used in the production of semiconductors and photovoltaic devices, such as solar cells, due to its unique optical and electronic properties. It has a direct band gap of approximately 2.4 eV, making it suitable for absorbing light in the visible spectrum.

Despite its useful properties, lead iodide is toxic and must be handled with care. It can be harmful if ingested or inhaled, and exposure to high levels of lead can lead to serious health issues. Proper safety precautions should be taken when handling lead iodide to minimize the risk of exposure.
