A novel 3D star-shaped acceptor based on triphenylamine as a core and diketopyrrolopyrrole as arms (S(TPA–DPP)) was synthesized. S(TPA–DPP) exhibited excellent thermal stability, strong absorption, and very high open-circuit voltage (1.18 V) in solution-processed organic solar cells based on P3HT : S(TPA–DPP).
