Ossila 3-BPIC-F M2464A1

3-BPIC-F (IDCz-2F) is a self-assembled monolayer (SAM) compound used as a hole transport or hole extraction layer in non-fullerene acceptor polymer solar cells and p-i-n perovskite solar cells. Its structure combines an electron-rich 3,8-difluoroindolo[2,3-a]carbazole terminal group with two phosphonic acid anchors, each linked through a propanyl spacer.

As the fluorinated counterpart of 3-BPIC, it carries electron-withdrawing fluorine atoms that give ITO/3-BPIC-F substrates a larger work function, a deeper HOMO level and a stronger dipole moment. Acting as the hole-selective contact, the monolayer speeds hole extraction and reduces interfacial impedance, which limits nonradiative recombination at the interface. Organic cells using it between anode and active layer show better operational stability than equivalents built on PEDOT:PSS.

A power conversion efficiency of 19.71% has been reported for a device with the structure ITO/3-BPIC-F/PM6:L8-BO:BTP-ec9/PNDIT-F3N/Ag. The material is deposited from solution at low concentration (around 1 mM) in solvents such as ethanol, methanol, IPA, DMF or THF, and is supplied as a white powder or crystals with > 98% (HPLC) purity.
