Transistor and solar cell performance of donor–acceptor low bandgap copolymers bearing an acenaphtho[1,2-b]thieno[3,4-e]pyrazine (ACTP) motif

Abstract

We report the performance of low-bandgap polymers with a new ACTP acceptor in organic transistors (max. field-effect mobility 0.2 cm2V−1s−1), and solar cells (max. efficiency 1.4%).
