摘要
以三种给电子能力不同的给体单元(噻吩,并噻吩,三并噻吩)与萘酰亚胺为受体共聚,合成了三种n-型聚合物P(NDI-T),P(NDI-TT)和P(NDI-TDT)。以中等带隙p-型聚合物J51作为给体制备的全聚合物太阳能电池的最佳光电转换效率分别为2.59%(P(NDI-T)),3.70%(P(NDI-TT))和5.10%(P(NDI-TDT))。因此,具有强的给电子能力的三并噻吩有助于降低D-A共聚物的带隙,拓宽吸收从而提高全聚合物太阳能电池的光伏性能。
Three n-type alternating D-A copolymers based on naphthalenediimide(NDI) acceptor(A) unit and three different donor(D) units including thiophene(P(NDI-T)), thieno[3,2-b]thiophene(P(NDI-TT)), and thieno[3,2-b;4,5-b]dithiophene(P(NDI-TDT)), were synthesized, for the applicaiotn as acceptor materials in all-polymer solar cells(all-PSCs). With J51 as polymer donor, The power conversion efficiency reached 2.59%, 3.70% and 5.10% for the all-PSCs with P(NDI-T), P(NDI-TT) and P(NDI-TDT) as acceptor, respectively. The results indicate that the larger conjugated fused molecular plane with more thiophene rings as donor units in the D-A copolymers will benefit to reduce the bandgap, broaden the absorption and enhance the photovoltaic performance of the n-type D-A copolymer acceptors.
