Highly Soluble Semiconducting Polymer
Polymer donor which achieves device efficiencies of >16%
Overview | Specifications | MSDS | Literature and Reviews | Technical Support
PBDB-TF-T1 is a randomly copolymerized 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 PM6 and PTO2, relatively blue shifted in absorption to PM6 and red shifted to PTO2.
This polymer is also relatively more soluble in non-halogenated solvents, i.e. o-xylene, 1,2,4‐trimethylbenzene or THF than PM6. Non-fullerene polymer solar cells withnon-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%.
