| 英文摘要 | Two new conjugated D-A polymers P3 (PBTT-d-BTT) and P4 (PBTT-d-TPD) based on same benzo[1,2-b:3,4-b':6,5-b ''] trithiophene (BTT) donor and different acceptors monomers 5,8-dibromo-2-dodecanoylbenzo[1,2-b:3,4-b':6,5-b ''] trithiophene (d-BTT), and 1,3-dibromo-5-(2-ethylhexyl)thieno[3,4]pyrrol-4,6-dione (d-TPD) respectively, were synthesized by Stille cross-coupling reaction and characterized by gel permeation chromatography (GPC), H-1 NMR, UV-Vis absorption, thermal analysis and electrochemical cyclic voltammetry (CV) tests. Photovoltaic properties of the polymers were studied by using the polymers as donor and PC71BM as acceptor with a weight ratio of polymer: PC71BM 1:1, 1:2 and 1:2.5. The optimized photovoltaic device was fabricated with an active layer of a blend P3:PC71BM and P4:PC71BM with a blend ratio of 1: 2 showed PCE 3.16% and 2.42%, respectively under illumination of AM 1.5 at 100 mW/cm(2) with solar simulator. The PCE of the device based on P3:PC71BM processed with DIO/o-DCB has been further improved up to 4.64% with J(sc) of 10.52 mA/cm(2) and FF of 0.58 attributed to the increase in crystalline nature of active layer and more balanced charge transport in the device, induced by DIO additive.
