Application

PBDTS-TDZ is a wide bandgap polymer that can be used as a donor for the fabrication of organic solar cells. It has alkylthio side chains, which help in strong optical absorption and high crystallinity. PBDTS-TDZ forms a composite with ITIC, which has an efficiency of ~18% for organic tandem solar cells.

Two novel wide-bandgap copolymers, PBDT-TDZ and PBDTS-TDZ, are developed based on 1,3,4-thiadiazole (TDZ) and benzo[1,2-b:4,5-b']dithiophene (BDT) building blocks. These copolymers exhibit wide bandgaps over 2.07 eV and low-lying highest occupied molecular orbital (HOMO) levels below -5.35 eV, which match well
