Product code: SV003-4N and SV003-5N Formamidinium iodide is one of the most common precursors used in the preparation of perovskite-based opto-electronic systems, including light-emitting diodes (LEDs) and perovskite solar cells (PSCs). Perolink offers standard purity grades of >99.99 % and 99.999 % (Trace Metal Basis). Higher purity grades are available on demand. Please contact us for more information or such a request. Furthermore you can contact us in need for larger amounts than stated in the Online Store.
