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.

PBDB-T, a conjugated push-pull medium bandgap polymeric donor, can be used as a donor molecule that can be used in polymeric solar cells (PSCs). It can also be used in the fabrication of organic thin-film transistors (OTFTs).
