【 摘 要 】

To enhance the charge transfer efficiency of bulk heterojunction materials, a nanostructure comprising blended PDPPBTT and PC71BM prepared via the porous alumina template-assisted method was proposed. Both materials were dissolved in chloroform in a 1:1 ratio at two different concentrations (5 and 10 mg mL-1) and infiltrated into the nanopore template using a centrifuge method. The characterization results showed that one-dimensional nanostructures were successfully prepared. The high concentration solution resulted in nanostructures with large diameters but short lengths, which could absorb light effectively. Moreover, the high concentration solution exhibited low photoluminescence intensity, thus indicating efficient charge transfer from PDPPBTT to PC71BM.
