Donor-acceptor conjugated polymers PBDT-DTBT and PBDT-DTNT, based on 2,1,3-benzothiadiazole (BT) and naphtho[1,2-c:5,6-c]bis[1,2,5]thiadiazole (NT), have been designed and synthesized for polymer solar cells. NT contains two fused 1,2,5-thiadiazole rings that lower the band gap, enhance the interchain packing, and improve the charge mobility of the resulting polymer. Consequently, the NT-based polymer PBDT-DTNT
供体-受体共轭聚合物 PBDT-DTBT 和 PBDT-DTNT,基于 2,1,3-苯并噻二唑 (BT) 和萘并[1,2-c:5,6-c]双[1,2,5]噻二唑( NT),已被设计和合成用于聚合物太阳能电池。NT 包含两个稠合的 1,2,5-噻二唑环,可降低带隙、增强链间堆积并提高所得聚合物的电荷迁移率。因此,与基于 BT 的聚合物 PBDT-DTBT 相比,基于 NT 的聚合物 PBDT-DTNT 表现出明显更好的光伏性能,功率转换效率 (PCE) 为 6.00%,在相同的器件配置下,其 PCE 为 2.11%。
