Here, five polymer donors with different molecular orientations are synthesized by random copolymerization of 5‐fluoro‐2,1,3‐benzothiadiazole with different relative amounts of 2,2′‐bithiophene (2T) and dithieno[3,2‐<jats:italic>b</jats:italic>;2′,3′‐<jats:italic>d</jats:italic>]thiophene (DTT). Solar cells are prepared by blending the polymer donors with a naphthalene diimide‐based polymer acceptor (PNDI) or a [6,6]‐phenyl C<jats:sub>71</jats:sub>‐butyric acid methyl ester (PC<jats:sub>71</jats:sub>BM) acceptor and their morphologies and crystallinity as well as optoelectronic, charge‐transport and photovoltaic properties are studied. Interestingly, charge generation in the solar cells is found to show higher dependence on the crystal orientation of the donor polymer for the PNDI‐based all‐PSCs than for the conventional PC<jats:sub>71</jats:sub>BM‐based PSCs. As the population of face‐on‐oriented crystallites of the donor increased in PNDI‐based PSC, the short‐circuit current density (<jats:italic>J</jats:italic><jats:sub>SC</jats:sub>) and external quantum efficiency of the devices are found to significantly improve. Consequently, device efficiency was enhanced of all‐PSC from 3.11% to 6.01%. The study reveals that producing the same crystal orientation between the polymer donor and acceptor (face‐on/face‐on) is important in all‐PSCs because they provide efficient charge transfer at the donor/acceptor interface.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670318612022784","@type":"Researcher","foaf:name":[{"@value":"Jea Woong Jo"}],"jpcoar:affiliationName":[{"@value":"Photoelectronic Hybrid Research Center Korea Institute of Science and Technology  Seoul 02792 Korea"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318612022912","@type":"Researcher","foaf:name":[{"@value":"Jae Woong Jung"}],"jpcoar:affiliationName":[{"@value":"Photoelectronic Hybrid Research Center Korea Institute of Science and Technology  Seoul 02792 Korea"},{"@value":"Department of Materials Science and Engineering University of Washington  Seattle WA 98195 USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318612022785","@type":"Researcher","foaf:name":[{"@value":"Hyungju Ahn"}],"jpcoar:affiliationName":[{"@value":"Pohang Accelerator Laboratory  Kyungbuk, Pohang 37673 Korea"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318612022914","@type":"Researcher","foaf:name":[{"@value":"Min Jae Ko"}],"jpcoar:affiliationName":[{"@value":"Photoelectronic Hybrid Research Center Korea Institute of Science and Technology  Seoul 02792 Korea"},{"@value":"KU‐KIST Graduate School of Converging Science and Technology Korea University  Seoul 02841 Korea"}]},{"@id":"https://cir.nii.ac.jp/crid/1380298341256541952","@type":"Researcher","foaf:name":[{"@value":"Alex K.‐Y.
