英國(guó)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)

General Information

英國(guó)Ossila材料PCE-12 OPV材料PBDB-T CAS:145929-80-4

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.
