PM6, for high performance OPV devices
High purity and available for priority dispatch
PBDB-T-2F is a PBDB-T family member and, like others, has a high OPV device performance. Polymer solar cells with PBDB-T-2F as the donor and ITIC-2F as the acceptor have achieved a power conversion efficiency (PCE) of over 13%.
By introducing two fluorine atoms to each thiophene unit of the benzodithiophene (BDT) side chains in PBDB-T, the HOMO/LUMO energy levels are pulled. Complete phase separation is observed in the PBDB-T-2F:ITIC-2F blend due to the distinct surface tension difference between PBDB-T-2F and ITIC-2F, resulting in a high domain purity in the blend.
A certified efficiency of 14.9% has been demonstrated using PBDB-T-2F (PM6) as the electron donor and Y6 as an acceptor in a single junction non-fullerene polymer solar cell (NF-PSC) [2].
PBDB-T-2F from Ossila was used in the high-impact paper (IF 18.81), Stretchable and Transparent Conductive PEDOT:PSS-Based Electrodes for Organic Photovoltaics and Strain Sensors Applications, E. Dauzon et al., Adv. Fun. Mater., 30 (28), 2001251 (2020); DOI: 10.1002/adfm.202001251.
