PBDD4T-2F (CAS 1890205-85-2) is a polymer semiconductor developed for OPV applications, including both fullerene and non-fullerene polymer solar cells, with an efficiency of over 9% [1]. It has been built into tandem solar cells, and a PCE reaching 13% was reported with the following structure: PBDD4T-2F:PC71BM (front cell) & PBDTTT-E-T:IEICO (rear cell) [2].
When compared to PBDD4T, it has a stronger tendency to aggregate in solution, a stronger π–π stacking compact in solid thin-films, and shows a deeper HOMO energy level of -5.39 eV. PBDD4T-2F finds applications in polymer solar cells with both fullerene and non-fullerene acceptors (such as ITIC and P(NDI2OD-T2) respectively) with highly efficient device performances.
