Abstract

Abstract : A DPP molecule has appropriate energy levels and bipolar charge-transport properties for both donor and acceptor in OSCs. Abstract : A new diketopyrrolopyrrole derivative with appropriate energy levels and bipolar charge-transport properties is designed and synthesized. When this molecule is used as either electron donor or acceptor, the resulting organic solar cells both give the power conversion efficiencies over 3%.
