Bulk heterojunction all-polymer solar cells have attracted much interest due to the possibility of achieving high open-circuit voltage and more efficient light absorption compared to polymer/fullerene blend system. However, molecular engineering of the morphological aspect of all-polymer devices has proven more difficult as compared to polymer:fullerene devices. In addition, the anisotropic charge transport properties of the polymers require careful control of their packing structure and orientation suitable for their use in all-PSCs. Here, we investigated the phase separation mechanism of all conjugated polymer blend via adjusting composition ratio, film drying time and D/A interaction by additive to construct BHJ morphology with decreased domain size. Furthermore, by changing polymer solution aggregation state and film drying time, we obtained the face-on/face-on molecular orientation for donor and acceptor, which could be benefit for efficient dissociation of excitons, leading the efficiency improved.
