Cover Story

Many  donor-acceptor  (D-A) type  conjugated  polymers can  self-assemble  into fibrils of nanometers with a long axis parallel to conjugated backbone, and charge transport in their in-chain is highly efficient. The fibrillar assembly can construct the morphological framework by forming a network structure, as the morphology of blue fibers in the figure. Such a morphology, using fibrils to form the hole transporting network, and adopting acceptor (e.g. the fullerenes in the figure, represented by yellow spheres) inserted in-between the fibril network to transport electrons, is particularly analogous to the desired bulk-heterojunction (BHJ) bicontinuous network, which is quite favorable for organic solar cells. Figuratively, the donor fibril network in the active layer is like a highway network, where excitons are separated into electrons and holes at the interface between thedonor fibrils and the acceptors, and the holes can be rapidly diffused along the highway network of fibrils to the electrode, thus eventually improving the device performances. We define it as “fibril network strategy” (FNS) (see the perspective by Tian Xia, Yunhao Cai, Huiting  Fu & Yanming Sun on pages 662‒668).
