A regular alternating terpolymer design strategy is used to create a semiconducting polymer with tailored energy levels and optical band gap. Combined with a modified synthetic procedure for the polymerization reaction, high‐molecular‐weight polymers of the terpolymer as well as the parent co‐polymers were obtained with high efficiencies (up to 8.0 %) in organic solar cells when combined with [70]PCBM.
