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 (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 .
