详情介绍：

PBDB-TF-T1 is a randomly copolymerised conjugated semiconducting polymer with benzodithiophene (BDT), Benzodithiophene dione (BDD) and thiophene carboxylate ester as the main backbone units. PBDB-TF-T1 is a close relative in structure to PBDBT-2F (PM6) and PTO2, relatively blue shifted in absorption to PM6 and red shifted to PTO2.

PBDB-TF-T1 is also relatively more soluble in non-halogenated solvents, i.e. o-xylene, 1,2,4‐trimethylbenzene or THF than PM6. None-fullerene polymer solar cells with non-halogenated solvent additive DIO from BTP-4F-12 as acceptor and PBDB-TF-T1 as polymer donor achieved high device performance efficiencies of PCE = 16.1%.

Please refer to our collection of green energy materials for non-halogenated solvents processing choice of non-fullerene acceptors (NFAs).

Device structure: indium tin oxide (ITO)/PEDOT:PSS/T1:BTP-4F-12/PFN-Br/Al. [1]
