High Quality Polymer Donor with a Simple Structure
Achieve OPV device performance efficiencies of >14%
Overview | Specifications | MSDS | Literature and Reviews | Technical Support
PTO2 is an alternating wide band-gap copolymer with electron-donating benzodithiophene (BDT) and electron-withdrawing thiophene carboxylate ester as the main backbone units. It has good solubility in non-halogenated solvents, i.e. xylenes and THF. With an efficient charge generation at a low driving force, an efficiency of 14.7% was achieved in a single-junction OPV by using polymer donor PTO2 and a non fullerene acceptor IT-4F.
PTO2, as well as PClTO2, is considered as good replacement for PBDB-T-2F (PM6) or PTB7-Th because it has a similar but simpler structure, while maintaining great device performance efficiencies at lower costs.
