Alkoxy‐Substituted Anthrabis(Thiadiazole)‐Terthiophene Copolymers for Organic Photovoltaics: A Unique Wavy Backbone Enhances Aggregation, Molecular Order, and Device Efficiency

open access: yesChemistry – An Asian Journal, EarlyView.
By incorporating a lower‐symmetry terthiophene donor unit in place of quaterthiophene, the resulting ATz‐based polymer donors exhibit reduced aggregation, improved solubility, and a favorable shift in molecular orientation from edge‐on to face‐on. As a result, solar cells based on the PATz3T‐o6HD:Y12 system demonstrated a remarkable improvement in PCE,
