Description

FORMAMIDINIUM IODIDE CH₃IN₂ 99% FAI CAS 879643-71-7

RESEARCH GRADE MATERIAL

Product Overview
Formamidinium Iodide (CH₃IN₂, FAI, CAS 879643-71-7) is a core formamidinium-based perovskite solar cell precursor with CH₃IN₂ 99% purity FAI, supplied as an off-white solid with a molecular weight of 171.97 g/mol. This high-purity organohalide salt is the key material for preparing high-stability formamidinium lead iodide perovskite thin films, which exhibit a narrower bandgap and superior thermal stability compared to methylammonium-based perovskite compositions. The enhanced optoelectronic properties of FA-based perovskites make FAI the preferred precursor for high-performance photovoltaic devices requiring improved spectral absorption and extended operational lifetimes. Widely utilized in university and research institute laboratories for perovskite solar cell, photodetector, and light-emitting device experimental research, this high-purity precursor is compatible with spin-coating, solution blending, and thermal evaporation thin-film preparation techniques. 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.

Key Features & Advantages
  • Narrower Bandgap for Enhanced Spectral Absorption: Formamidinium-based perovskites exhibit a bandgap closer to the optimal single-junction value, enabling broader solar spectrum utilization and higher theoretical power conversion efficiency compared to methylammonium-based compositions.
  • Superior Thermal Stability for Extended Device Lifetime: The formamidinium cation demonstrates significantly improved thermal resistance against decomposition compared to methylammonium, making FAI-based devices more stable under prolonged illumination and elevated operating temperatures.
  • Versatile Compatibility with Multi-Cation Engineering: FAI serves as the foundation for mixed-cation formulations incorporating MA, Cs, and Rb, enabling precise bandgap tuning and phase stability optimization in state-of-the-art high-efficiency perovskite devices.
  • Ultra-High Purity Exceeding 99%: Refined to >99% purity with low batch impurity content, the precursor minimizes extrinsic defects in perovskite thin films and supports reproducible device performance across spin-coating, solution blending, and thermal evaporation deposition techniques.

APPLICATION SCOPE: Primary formamidinium source for FAPbI₃ and mixed-cation FA-based perovskite light-absorbing layer synthesis. Key precursor for high-stability perovskite solar cells with improved thermal and moisture resistance. Essential component in mixed-cation mixed-halide formulations for bandgap-engineered photovoltaic devices. Compatible with one-step spin-coating, solution blending, and thermal evaporation deposition protocols. Supports perovskite solar cell, photodetector, and light-emitting device research in university and research institute laboratories where enhanced stability and narrower bandgap are experimental priorities.
PACKAGING: This listing is for the 10 g specification. Other packaging weights are available upon custom request. Each package is sealed under inert atmosphere within light-protective packaging to prevent photodegradation and moisture ingress. The strongly hygroscopic nature of formamidinium iodide necessitates immediate transfer to a desiccated, light-protected storage environment upon receipt. For bulk quantities or custom packaging specifications, please contact us via email.
IMPORTANT NOTICE: Formamidinium iodide is strongly hygroscopic and light-sensitive. Tighten the container cap immediately after each use to prevent moisture ingress from ambient air. 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 acidic reagents. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the off-white 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.
