A narrow band-gap alternating copolymer of perylene diimide and bis(dithienothiophene) (2) and a polythiophene derivative substituted by a tris(thienylenevinylene) conjugated side chain (4) are used as acceptor and donor, respectively, in all-polymer solar cells (SCs). The optimized device based on the blend of 4 and 2 in the ratio 3:1 (w/w) gives a short circuit current (Jsc) of 5.02 mA cm⁻²and a power conversion efficiency of 1.48%, under simulated AM 1.5 illumination at 100 mW cm⁻¹. These values are among the highest values reported for all-polymer SCs
