Abstract

Low band gap dyad molecules were prepared that have absorption spectra matched well with the solar spectrum, and the construction of efficient charge transport pathways was observed. Under AM 1.5 illumination, the devices have achieved the highest JSC (4.79 mA cm2) and FF (0.46) in dyad-based organic solar cells to date.
