A phase segregated hybrid assembly has been created of a p‐type diketopyrrolopyrrole (DPP‐Amide) and n‐type PC 71 BM. DPP‐Amide forms supramolecular fibers and PC 71 BM undergoes clustering on the fiber surface. Photoexcitation leads to the generation of excitons in the DPP fibers that travel along these fibers and dissociate at the DPP fibers/PC 71 BM clusters interfaces. This hybrid material exhibits enhanced intrinsic photoconductivity.
