Using a triple component random copolymerization approach , the amount of triethylene glycol (TEG) side chain , which can be regarded as a stack‐inducing agent, is introduced precisely into a given polymer backbone. TEG side chains result in a more favorable morphology in a polymer:fullerene blend. Based on the low‐bandgap photovoltaic polymer PBDTT‐DPP (PBD), this methodology can bring a 10% overall improvement in power conversion efficiency (PCE).
