Abstract

Abstract: A new low‐band gap dyad DPP‐Ful, which consists of covalently linked dithiafulvalene‐functionalized diketopyrrolopyrrole as donor and fullerene (C60 ) as the acceptor, has been designed and synthesized. Organic solar cells were successfully constructed using the DPP‐Ful dyad as an active layer. This system has a record power‐conversion efficiency (PCE) of 2.2 %, which is the highest value when compared to reported single‐component organic solar cells.
