Formamidinium iodide is an organic halide salt that serves as a critical precursor material in the synthesis of formamidinium lead iodide perovskites. With the molecular formula CH5IN2 and CAS# 879643-71-7, this white crystalline powder is highly soluble in water and delivers efficient performance in optoelectronic applications. The compound has a molecular weight of 171.97 and demonstrates strong thermal stability.
As a key building block for perovskite solar cells, formamidinium iodide enables the formation of materials with optimal bandgap characteristics around 1.48 eV. This narrower bandgap enables broader near-infrared absorption than alternative organic cations, resulting in enhanced power conversion efficiency. The material’s stability and performance make it valuable for researchers and manufacturers pursuing high-efficiency photovoltaic solutions that support ongoing advances in photovoltaic efficiency.
For optimal results in device fabrication, formamidinium iodide should be stored under inert gas conditions to prevent moisture absorption. We supply ultra-high-purity grades with low water content, helping reduce nonradiative recombination losses. Proper handling and storage extend the material’s shelf life and maintain its effectiveness in perovskite synthesis.
Formamidinium iodide is widely used in renewable energy research and commercial photovoltaic manufacturing.
FAI serves as the primary organic precursor for formamidinium lead iodide perovskite materials, which have achieved power conversion efficiencies exceeding 25% in laboratory settings. These cells exhibit superior thermal stability and longer carrier diffusion lengths than methylammonium-based alternatives. The enhanced stability reduces degradation pathways and can support stable device performance.
Researchers use formamidinium iodide in mixed-cation perovskite formulations to optimize bandgap properties, enhance phase stability and improve overall device longevity. A-site engineering with FAI primarily governs the thermodynamic stability of the perovskite phase. This compositional flexibility enables precise tuning of absorption spectra and electronic properties to meet specific application requirements.
Beyond photovoltaics, formamidinium iodide enables the development of light-emitting diodes, photodetectors and other optoelectronic components that benefit from its favorable electronic properties and processing characteristics. The material’s compatibility with solution-based processing methods makes it attractive for large-scale manufacturing.
Academic institutions and industrial research laboratories rely on high-purity formamidinium iodide to study phase transitions, defect chemistry and composition engineering strategies for advancing perovskite technology toward commercial viability. Understanding the fundamental properties of FAI-based systems continues to drive innovation in the field.
