英文摘要	two d-a conjugated polymers (named pbdtc6bt and pbdtc10dbt) with benzo[1,2-b:3,4-b']thiophene (bdt) as donor and 4,7-dithiophen-2,1,3-benzothiadiazole (dbt) as acceptor, were designed and synthesized. pbdtc6dbt and pbdtc10dbt have hexyl and decyl as side chains in the dbt units, respectively. the polymers were characterized by spectroscopic (nmr and uv-vis) methods, gpc, dsc and cyclic voltammetry. in order to study the photovoltaic properties of the two conjugated polymers, photovoltaic devices with the configuration of ito/poly(3,4-ehylenedioxythiophene)-poly(styrenesulfonate) (pedot:pss)/polymer:[6,6]-phenyl c-61-butyric acid methyl ester (pc61bm)/lif/al, were fabricated, in which pbdtc6dbt or pbdtc10dbt acted as electron donor in active layers. according to the experimental data, when the blend ratio of pbdtc6dbt and pc61 bm reached 1:2, the best photovoltaic properties among the pbdtc6dbt-based devices were obtained, and the open-circuit voltage, the short-circuit current density and the power conversion efficiency were measured to be 0.63 v, 6.18 ma/cm(2) and 1.86%, respectively. as to pbdtc10dbt-based devices, the maximum of power conversion efficiency reached 0.99% with the blend ratio of pbdtc10dbt and pc61bm being 1:2. pbdtc10dbt and pbdtc6dbt were both promising donor candidates in the application of polymer solar cells.
