PBDD4T-2F, for highly efficient OPV devices
High purity and available online for priority dispatch
PBDD4T-2F polymer semiconductor has been developed for OPV applications (including both fullerene and non-fullerene polymer solar cells) and has an efficiency of over 9% . It has been built into tandem solar cells, and PCE reaching 13% was reported with the following structure: PBDD4T-2F:PC71BM (front cell) & PBDTTT-E-T:IEICO (rear cell) .
When compared to PBDD4T, PBDD4T-2F has a stronger tendency to aggregate in solution. It also has a stronger π–π stacking compact in solid thin-film, and shows a deeper HOMO energy level of -5.39 eV.
Luminosyn™ PBDD4T-2F is now available.
High purity and high molecular weight
PBDD4T-2F is purified by Soxhlet extraction with methanol, hexane and chlorobenzene under an argon atmosphere - polymer at its pure best
