Descripción

General description

Lead(II) iodide (PbI₂) is a compound with significant potential in the field of material science due to its unique characteristics, including its crystal structure, optical properties, and electronic behavior. Its applications in various areas such as photovoltaics, optoelectronics, and semiconductor devices, making it a subject of extensive research and development.,Lead iodide is a direct wide bandgap semiconductor with unique properties like high thermal conductivity, high electron saturation velocity, chemical stability, and wide temperature range operation capabilities (−200 °C up to +130 °C). Itis widely used as an x- and γ-ray detector, as it shows high absorption and carrier collection with minimal noise. PbI₂ is also used in solar cells, bioimaging, and photoconductors.

Application

Lead(II) iodide can be used as:      

• A precursor salt in the fabrication of perovskite solar cells. The addition of a small molar excess of PbI₂ to the precursor solution can enhance device performance by improving charge extraction.     
• A potential electrode material in battery configurations due to its electrochemical properties. Its ability to undergo reversible reactions makes it a candidate for use in lead-based batteries.      
• A key component in combination with lead monoxide (PbO) to create a stable and sensitive semiconductor detector material for non-destructive testing (NDT) radiation dose detection.      
• A key component to develop X-ray detectors for medical imaging.      
• To prepare cesium lead iodide perovskite quantum dots for highly stable LEDs.
