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% . These efficiencies were achieved when PBDB-T was used in conjunction with recently-reported non-fullerene acceptors (NFAs, 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 potentially used as a hole-transporting material in perovskite solar cells .
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.
