PBDB-T-2Cl (PM7)
PBDB-T-2Cl, used to achieve efficiencies exceeding 12%
High quality polymer available for fast, secure dispatch
PBDB-T-2Cl, also known as PM7, is part of the PBDB-T polymer family. It has a high OPV device performance, with reported efficiencies exceeding 12%. PSCs based on PBDB-T-2Cl as the donor and ITIC-2F as the acceptor have achieved a power conversion efficiency (PCE) of over 14%.
Compared to PBDB-T-2F, PBDB-T-2Cl showed slightly lower calculated HOMO levels. Although fluorine has greater electronegativity, it is believed that electron density can be delocalised more effectively to the chlorine atom than the fluorine atom on the BDT (benzodithiophene) backbone unit, resulting in a deeper HOMO energy level.
