We report a new series of wide band-gap small organic molecules as donor-materials featuring an indaceno[1,2-b:5,6-b′]dithiophene (IDT) core and fluorinated thiophene linkers for solution-processed organic solar cells.
Most polymer donors developed so far for high-performance non-fullerene OSCs are designed in planar molecular geometries containing BDT units. In this work, two D−A conjugated polymers with wide band gap,...
Two wide band gap donor polymers based on benzo[1,2-b:4,5-b′]dithiophene (BDT) and pyrrolo[3,4-f]benzotriazole-5,7(2H,6H)-dione (TzBI), namely, PBDT-TzBI and PBDT-F-TzBI were synthesized and studied in solar cells with ITIC as an acceptor.
