OP6167 Methylammonium Bromide (CAS No. 6876-37-5)

Methylammonium Bromide Description

Methylammonium Bromide (MABr) is an organic salt with the chemical formula CH₃NH₃Br. It consists of a methylammonium cation (CH₃NH₃⁺) and a bromide anion (Br⁻). MABr is primarily used in the fabrication of perovskite materials, which are applied in solar cells, light-emitting diodes (LEDs), and other optoelectronic devices.

Methylammonium Bromide Specification

Methylammonium Bromide Applications

• Perovskite Solar Cells: MAI is a key precursor in forming methylammonium lead iodide (CH₃NH₃PbI₃ or MAPbI₃), a perovskite material that is widely used as the light-absorbing layer in perovskite solar cells due to its excellent photovoltaic properties.
• Light-Emitting Diodes (LEDs): MAI is also used in the fabrication of perovskite-based LEDs (PeLEDs), which exhibit efficient light emission properties.
• Photodetectors and Lasers: MAI-based perovskites are used in various other optoelectronic devices, such as photodetectors and lasers, because of their tunable optical properties.

FAQs

Q1: What is the role of Methylammonium Bromide in perovskite solar cells?

Answer: MABr is used to form methylammonium lead bromide (MAPbBr₃), a type of perovskite material with a higher bandgap (~2.2 eV). This makes it suitable for tandem solar cells and other applications requiring wider bandgap materials for improved light absorption and conversion efficiency.

Q2: What are the benefits of using Methylammonium Bromide-based perovskites?

Answer: MABr-based perovskites offer several advantages:

• Wider Bandgap: MAPbBr₃ has a larger bandgap than iodide-based perovskites, making it useful for tandem solar cells.
• High Efficiency: MABr can help produce perovskite materials with excellent optoelectronic properties, including efficient light absorption and emission.
• Application in LEDs: MABr-based perovskites are also used in light-emitting diodes (LEDs), where they exhibit strong green light emission.

Q3: How does Methylammonium Bromide compare to Methylammonium Iodide in perovskites?

Answer: Methylammonium Bromide (MABr) forms perovskites with a higher bandgap (~2.2 eV for MAPbBr₃) compared to Methylammonium Iodide (MAI), which forms perovskites with a lower bandgap (~1.55 eV for MAPbI₃). This makes MABr more suitable for tandem solar cells and optoelectronic devices requiring green light emission, while MAI is typically used for single-junction solar cells.
