Abstract

A new non-fullerene acceptor PDFC is prepared by introducing perylene diimide into the core of an A–DA′D–A architecture. Due to the large conjugation and electron-deficient ability of perylene diimide, PDFC shows strong absorption, suitable energy levels and favorable face-on packing. The optimal device realizes a PCE of 12.56% with one of the highest fill factors (81.3%). A PCE of 9.66% is obtained in a 570 nm thick-film device based on PDFC.
