Application
Formamidine HydroBromide (Low water content) serves a crucial role in the development of advanced solar cell materials. This precursor is specifically designed for synthesizing mixed cation or anion perovskites, which are essential for optimizing the band gap, carrier diffusion length, and power conversion efficiency in perovskite-based solar cells. As a precursor mainly for compounds like FAPbBr3 and formamidinium lead bromide-iodide mixed halide perovskites (FAPbIyBr3-y), it helps achieve precise control over the material's properties. The ability to adjust the halide ratios in these structures allows for bandgap tuning between 1.55 eV and 2.3 eV, resulting in extended photoexcited species lifetime, enhanced charge transport, and improved performance in multi-junction solar cell applications. Specifically, FAPbBr3 with its 2.23 eV energy bandgap is particularly effective for tandem solar cell use, highlighting the critical function Formamidine HydroBromide plays in the production of high-efficiency photovoltaic solutions.
