PTO2, high quality polymer donor
Simple structure with great device performance efficiencies
PTO2 is an alternating wide band-gap copolymer with electron-donating benzodithiophene (BDT) and electron-withdrawing thiophene carboxylate ester as the main backbone units. PTO2 enjoys 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 nonfullerene acceptor IT-4F.
PClTO2, a chlorine version of PTO2, is also available to our customers. Please refer to our collection of green energy materials for non-halogenated solvents processing choice of non-fullerene acceptors (NFAs).
