PFN-FP, used to improve extraction efficiencies in OPV devices

High quality polymer available for fast, secure dispatch

PFN-FP is one of the family members of conjugated poly-electrolyte materials (such as PFN) which is used as an electron-interface layer material in OPV devices (including perovskite solar cells) to improve extraction efficiencies. PFN-FP is also used as an active-layer material for blue OLED devices.

PFN-FP is soluble in polar solvents (such as water and methanol) in the presence of small amounts of acetic acid.
