Alkoxy-Substituted Anthrabis(Thiadiazole)-Terthiophene Copolymers for Organic Photovoltaics: A Unique Wavy Backbone Enhances Aggregation, Molecular Order, and Device Efficiency.
Two polymer donors, PATz3T-o6BO and PATz3T-o6HD, incorporating alkoxy-substituted anthra[1,2-c:5,6-c']bis([1,2,5]thiadiazole), were strategically designed and synthesized. The unique wavy backbone of these polymers effectively reduced aggregation, leading to enhanced solubility and significantly improved molecular ordering. Consequently, the PATz3T-o6HD:Y12-based solar cells achieved a power conversion efficiency (PCE) of 7.94%. These findings provide valuable insights into the molecular design of high-performance polymer donors for organic photovoltaics (OPVs).
期刊介绍:
Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics.
Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews.
A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal.
Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
