Ossila stays updated on the latest academic breakthroughs from research groups worldwide working with OPV and OLED materials. As such, we have developed new products to provide you with easy, affordable access to the most recent and advanced materials.

Among the materials that are used with non-fullerene acceptors (NFAs) for OPV devices, PJ61 (J61) and PJ71( J71) are making waves as medium band-gap 2D materials that can achieve high device performance efficiencies. Both PJ61 and PJ71 are polymers with benzodithiophene-alt-benzotriazole backbones, and have enhanced stability due to their deeper HOMO energy levels and wider band-gaps - all of which makes them a great match for most acceptors (including fullerenes and NFAs). 

Also added to our collection are PBDTTPD and PBDTTTPD, which are both capable of achieving high device performance efficiencies. They possess low-lying HOMO energy levels, which promotes device stability and produces higher VOC values (due to the TPD unit's electron-withdrawn nature with planar structures).
