New wide bandgap conjugated D-A copolymers based on Benzo[d]thiazole for efficient photovoltaics

Cost-effective polymer donors with simple structure for organic solar cells

“…Furthermore, non-covalent N⋯S and S⋯H interactions favor the coplanarity of the polymer skeleton. Luo et al 118 constructed two polymer donors PBTz-F and PBTz-Cl (Fig. 9) with BenTz as the acceptor unit and BDT as the donor unit.…”
