Side‐Chain Tunability via Triple Component Random Copolymerization for Better Photovoltaic Polymers

Side‐Chain Tunability via Triple Component Random Copolymerization for Better Photovoltaic Polymers 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). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advanced Energy Materials Wiley

Abstract

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).
