OP6166 Methylammonium Iodide (CAS No. 14965-49-2)

Methylammonium Iodide Description

Methylammonium iodide (MAI) is an organic salt with the chemical formula CH₃NH₃I. It consists of a Methylammonium cation (CH₃NH₃⁺) and an Iodide anion (I⁻). This compound is frequently used for synthesising perovskite materials, particularly for perovskite solar cells and other optoelectronic devices.

Methylammonium Iodide Applications

• Perovskite Solar Cells: MAI is a crucial precursor in forming Methylammonium Lead Iodide (CH₃NH₃PbI₃ or MAPbI₃), a perovskite material commonly used as a light-absorbing layer in perovskite solar cells due to its excellent photovoltaic properties.
• Light Emitting Diodes (LEDs): MAI is also utilised in the production of perovskite-based LEDs (PeLEDs), exhibiting efficient light emission characteristics.
• Photodetectors and Lasers: Perovskites based on MAI are employed in various other optoelectronic devices, such as photodetectors and lasers, due to their tunable optical properties.

FAQs

Q1: How is Methylammonium Iodide used in solar cells?

Answer: MAI is a significant precursor in the formation of Methylammonium Lead Iodide (MAPbI₃), a perovskite material used as the active layer in perovskite solar cells. This layer absorbs sunlight and converts it into electricity, making MAI essential for manufacturing high-efficiency photovoltaic devices.

Q2: What is the difference between Methylammonium Iodide and Formamidinium Iodide in perovskites?

Answer: MAI and Formamidinium Iodide (FAI) are both used in perovskites, but they form perovskite materials with differing properties. MAPbI₃ perovskites (produced with MAI) generally have a bandgap of approximately 1.55 eV and offer a good initial efficiency, but are less stable than FAPbI₃ perovskites (produced with FAI), which exhibit better thermal and moisture stability.

Q3: What are the common purity grades of Methylammonium Iodide?

Answer: MAI is typically available in high purity grades, ranging from 99% to 99.99% depending on the application. A high purity level is crucial for optimal performance of perovskite solar cells, as impurities can adversely affect the efficiency and stability of the perovskite film.
