英國Ossila材料PCE-12 OPV材料PBDB-T CAS:145929-80-4
PBDB-T (PCE12) is now available, featuring:
- Higher/lower molecular weights (so control experiments can be conducted)
- High purity (PBDB-T is purified by Soxhlet extraction with methanol, hexane and chlorobenzene under an argon atmosphere)
- Batch-specific GPC data (so you have confidence in what you are ordering. Also, GPC data is always convenient for your thesis and publications)
- Large-quantity orders (so you can plan your experiments with polymers from the same batch)

Applications
PBDB-T (PCE12) is one of the highest-performing donor polymers for OPVs, having reported efficiencies exceeding 12% [1, 2], and a certified efficiency approaching 11% [3]. These efficiencies were achieved when PBDB-T was used in conjunction with recently-reported non-fullerene acceptors (including ITIC) in inverted architecture devices. These devices also exhibited excellent thermal stability, making the combination a promising candidate for the proposed 10/10 target of 10% efficiency and 10-year lifetimes.
PBTB-T (PCE12) is easy to process, simplifying device fabrication while simultaneously providing high performance.
Due to good HOMO alignment with the valence band of commonly-used perovskites, this polymer could also be used as a hole-transporting material in perovskite solar cells .
Usage Details
The device structure of the certified devices was:
ITO / ZnO (30 nm) / PBDB-T:ITIC (100 nm) / MoO3 (10 nm) / Al (100 nm)
PBDB-T:ITIC solution details:
- Blend ratio: 1:1,
- Concentration: 20 mg/ml,
- Solvent: Chlorobenzene
- Additive: 0.5% Diiodooctane.
