Abstract

Abstract : Fullerene‐free polymer solar cell devices based on a new acceptor, H‐tri‐PDI that is connected by three perylene diimide (PDI) units via imide position shows a power conversation efficiency of 7.25% with a short circuit current density of 16.5 mA cm −2 . Thus H‐tri‐PDI molecules and the method of connecting multiple PDI units via imide position provide a reliable guide for the further development of PDI‐based acceptors.
