With the increasing concern for discovering a new processing additive, the effects of polymer additives (PS, PS-b-PPFS and PPFS) were thoroughly investigated for OSCs.
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,...
