Abstract

Two novel perylene diimide tetramer-based non-fullerene acceptors, PDIPQ-C5 and PDIPQ-C6, with different alkyl chain lengths were synthesized. Side-chain effects were studied by theoretical calculations, grazing incident X-ray diffraction, and atomic force microscopy. Organic solar cells based on PDIPQ-C5:P3TEA blend films with 2.5% DIO solvent additive exhibited the highest PCEs (5.16%).
