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).
两种包含烷氧基取代的蒽[1,2-c:5,6-c']双([1,2,5]噻二唑)的聚合物给体PATz3T-o6BO和PATz3T-o6HD经过精心设计与合成。这些聚合物独特的波浪状主链有效减少了聚集，从而提高了溶解性并显著改善了分子排列。因此，基于PATz3T-o6HD:Y12的太阳能电池实现了7.94%的功率转换效率。这些发现为有机光伏（OPV）高性能聚合物给体的分子设计提供了有价值的见解。
