Abstract

A novel conjugated D-A polymer, PTBFBz, with asymmetrical thieno[2,3-f]benzofuran (TBF) and fluorobenzotriazole (Bz) units was designed and synthesized for the first time. PTBFBz showed the strong absorption with a wide bandgap of 1.89 eV. Power conversion efficiency of nonfullerene polymer solar cells based on PTBFBz:ITIC with thermal and sequential solvent annealing reached up to 8.33%, which is the highest reported value among the asymmetrical TBF-based polymer solar cells. The results demonstrate that the asymmetrical TBF unit can be one of the most promising building blocks in constructing the wide bandgap polymers for highly efficient polymer solar cells.
