摘要

In this work, the organic optoelectronic devices with both photovoltaic and detection performance were fabricated based on a blend of the polymer poly[(2,6-(4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)-benzo[1,2-b:4,5-b']dithiophene))-alt-(5,5-(1',3'-di-2-thienyl-5',7'-bis(2-ethylhexyl)benzo [1',2'-c:4',5'-c']dithiophene-4,8-dione))] (PBDB-T) with the non-fullerene acceptor of 3,9-bis(2-methylene-(3-(1,1-dicyanomethylene)-indanone)-5,5,11,11-tetrakis(4-hexylphenyl)-dithieno [2,3-d:2',3'-d']-s-indaceno[1,2-b:5,6-b'] dithio-phene) (ITIC). Meanwhile, the different hole transport layers (HTL) materials of N, N'-bis-(1-naphthyl)-N, N'-diphenyl-1, 1'-biphenyl-4, 4'-diamine (NPB) and N, N'-diphenyl-N, N'-bis(3-methyllphenyl)-(1,1'-biphen-yl)-4,4'-diamine (TPD) were adopted to modify the interface of organic active layer and Ag/MoO_3 electrode. The result showed that without thermal annealing of PBDB-T:ITIC, the photovoltaic device with TPD HTL exhibited an improvement in power conversion efficiency (PCE) from 4.45% to 5.26% compared with the control device without HTL. Moreover, by analyzing the dark current behavior after thermal annealing, it was found that the TPD HTL could effectively suppress the leakage current from Ag/MoO_3 electrode to the active layer. As a result, an efficient organic photo detector with a detectivity of 3.87×10~(10) Jones was achieved.
