Applications

PBDB-T-2Cl 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% [2].

Compared to PBDB-T-2F, PBDB-T-2Cl showed slightly lower calculated HOMO levels. This demonstrated that on the BDT (benzodithiophene) backbone unit, chlorine has an even stronger electron-withdrawing ability than fluorine.

Although fluorine has greater electron negativity, it is believed that electron density can be delocalised more effectively to the halogen atom in Th-Cl than in Th-F. Hence, a deeper HOMO energy level is produced.

Usage Details

The device structure of the certified device was:

ITO / ZnO (30 nm) / PBDB-T-2Cl:ITIC-2F (100 nm) / MoO3 (10 nm) / Al (100 nm)

PBDB-T:ITIC-2F solution details:

  • Blend ratio: 1:1
  • Concentration: 20 mg/ml
  • Solvent: Chlorobenzene
  • Additive: 1% 1,8-Diiodooctane
