以2，1，3-苯并噻二唑(BT)和萘并[1，2-c：5，6-二氮并[1，2，5]噻二唑(NT)为基础，设计合成了用于聚合物太阳电池的供体受体共轭聚合物PBDT-DTBT和PBDT-DTNT。NT含有两个稠合的1，2，5-噻二唑环，它们降低了带隙，增强了链间堆积，并改善了所得聚合物的电荷迁移率。因此，与BT基聚合物PBDT-DTBT相比，NT基聚合物PBDT-DTNT具有更好的光伏性能，功率转换效率(PCE)为6.00%，而BT基聚合物在相同器件配置下的PCE为2.11%。
Donor acceptor conjugated polymers PBDT-DTBT and PBDT-DTNT, based on 2,1,3-benzothiadiazole (BT) and naphtho[1,2-c:5,6-dbis[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 exhibited considerably better photovoltaic performance with a power conversion efficiency (PCE) of 6.00% when compared with the BT-based polymer PBDT-DTBT, which gave a PCE of 2.11% under identical device configurations.
