High performing donor polymer for OPVs, available with batch-specific data
Specifications | MSDS | Literature and Reviews
PBDB-T (PCE12), CAS number 1415929-80-4, is one of the highest-performing donor polymers for OPVs, having reported efficiencies exceeding 12% 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 (PCE12) from Ossila was used in the high-impact paper (IF 29.37), Sequentially Deposited versus Conventional Nonfullerene Organic Solar Cells: Interfacial Trap States, Vertical Stratification, and Exciton Dissociation, J. Zhang et al., Adv. Energy Mater., 1902145 (2019); DOI: 10.1002/aenm.201902145; and paper (IF 29.37), Design Rules for Polymer Blends with High Thermoelectric Performance, O. Zapata-Arteaga et al., Adv. Energy Mater., 12, 2104076 (2022); DOI: 10.1002/aenm.202104076.
PBTB-T (PCE12) is easy to process, simplifying device fabrication (using a glove box) 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.
