Abstract

While efficient charge generation despite ultra-low energy offsets (down to 0 eV offsets) between donor and acceptor in non-fullerene acceptor (NFA) based organic solar cells has been often reported, the physical meaning of this observation is discussable and unclear. In our work, in terms of a series of donor:NFA combinations, and by combining advanced experimental techniques and optical and electrical simualtions, the role of energetic offset and the pathways for carrier losses has been studied in detail.
