OP6168 Lead(II) Bromide (CAS No. 10031-22-8)

Lead(II) Bromide Description

Lead(II) Bromide (PbBr₂) is an inorganic compound composed of lead in the +2 oxidation state and bromine. It is a white or colorless crystalline solid that is sparingly soluble in water. Lead(II) bromide is commonly used in various chemical and industrial applications, particularly in the formation of perovskite materials for solar cells and optoelectronic devices.

Lead(II) Bromide Applications

• Perovskite Solar Cells: Lead(II) bromide is a key precursor in the production of perovskite materials like methylammonium lead bromide (MAPbBr₃) and formamidinium lead bromide (FAPbBr₃). These materials are used in tandem solar cells and optoelectronic devices, where they help capture light and convert it into electricity.
• Light-Emitting Diodes (LEDs): Lead(II) bromide is also used in the synthesis of perovskites for perovskite-based LEDs (PeLEDs), which exhibit efficient light emission, especially in the green-light region.
• Laboratory Reagent: PbBr₂ is used as a reagent in various chemical reactions, including the synthesis of other lead-based compounds and in research for new materials.
• Photographic Processes: Historically, lead(II) bromide has been used in some photographic processes, though its usage has declined with advancements in digital imaging technologies.

FAQs

Q1: Why is Lead(II) Bromide used in perovskite solar cells?

Answer: PbBr₂ is used in perovskite solar cells to create lead halide perovskite materials like MAPbBr₃ and FAPbBr₃. These materials have excellent light absorption and charge-carrier mobility, which enhance the efficiency of solar cells. The bromide variant, with its higher bandgap, is particularly useful for tandem solar cells.

Q2: How is Lead(II) Bromide stored?

Answer: PbBr₂ should be stored in a cool, dry place, away from moisture and heat. It is important to store it in airtight containers to prevent degradation, especially if it will be used in perovskite material synthesis.

Q3: Can Lead(II) Bromide be replaced with less toxic materials in perovskites?

Answer: Research is ongoing to find lead-free alternatives for perovskite solar cells, such as using tin (Sn) or bismuth (Bi) compounds, but they have yet to reach the same efficiency levels as lead-based perovskites. While alternatives exist, PbBr₂ remains the standard in high-performance perovskite materials due to its superior optoelectronic properties.
