Product Overview
|
| Methylammonium Iodide (CH₃NH₃I, MAI, CAS 14965-49-2) is a core iodine-based perovskite solar cell precursor with CH₃NH₃I 99% purity, supplied as a white crystalline solid with a molecular weight of 159.5 g/mol. This high-purity organohalide salt serves as the primary iodine source for MAPbI₃ and mixed-halide perovskite formulations, and is compatible with mainstream thin-film deposition techniques including spin-coating, vacuum thermal evaporation, and solution-based synthesis. The material exhibits excellent solubility in water, N,N-dimethylformamide, and dimethyl sulfoxide, with additional solubility in methanol and isopropanol. Due to its strongly hygroscopic nature, the product requires strict light-sensitive hygroscopic dry storage—sealed under inert atmosphere, protected from light, and maintained at room temperature—to prevent moisture-induced degradation prior to precursor solution preparation. |

Key Features & Advantages
|
- Ultra-High Purity Exceeding 99%: The methylammonium iodide is refined to >99% purity with low batch impurity content, minimizing extrinsic ionic defects in perovskite thin films and supporting reproducible device performance across spin-coating, vacuum evaporation, and solution-based fabrication workflows.
- Broad Solvent Compatibility for Versatile Processing: Excellent solubility in water, N,N-dimethylformamide, and dimethyl sulfoxide, with additional solubility in methanol and isopropanol, enables flexible precursor solution formulation across a wide range of perovskite deposition protocols.
- Defined Molecular Weight for Precise Stoichiometry: With a molecular weight of 159.5 g/mol, the precursor supports accurate molar calculations for MAPbI₃ and mixed-cation mixed-halide perovskite formulations, essential for bandgap engineering and compositional optimization studies.
- Room Temperature Storage Convenience: The material is stored at room temperature under light-protected, dry, sealed conditions, simplifying laboratory inventory management without requiring refrigeration or freezing equipment.

APPLICATION SCOPE: Primary iodine source for MAPbI₃ perovskite light-absorbing layer synthesis in single-junction solar cells. Essential precursor for mixed-cation mixed-halide perovskite formulations in high-efficiency photovoltaic research. Compatible with one-step spin-coating, two-step sequential deposition, vacuum thermal evaporation, and solution-based synthetic routes. Serves as the organic cation component in two-dimensional Ruddlesden-Popper phase perovskites. Supports photodetector, light-emitting diode, and other optoelectronic device research in university and institutional laboratory settings.
PACKAGING: This listing is for the 10 g specification. Each package is sealed under inert atmosphere within light-protective packaging to prevent photodegradation and moisture ingress. The strongly hygroscopic nature of methylammonium iodide necessitates immediate transfer to a desiccated, light-protected storage environment upon receipt. For bulk quantities or other packaging specifications, please contact us via email.
IMPORTANT NOTICE: Methylammonium iodide is strongly hygroscopic and light-sensitive. Tighten the container cap immediately after each use to prevent moisture ingress. Wear protective gloves throughout all experimental procedures to avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or strong acids. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the white crystalline solid within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). For detailed safety and handling information, consult the Safety Data Sheet prior to use.
