Acceptor-only Oligomers with High Coplanarity enable Efficient and Stable Organic Solar Cells Acceptor-only oligomers are firstly developed as guest component to construct oligomer-assisted active layer for high performance organic solar cells. Due to the high planarity and structural similarity with host polymer donor, BDD-based acceptor-only oligomers form alloy phase with PM6 and optimize phase morphology effectively, achieving stable device with 18% efficiency.
