摘要：
To improve the properties of polymer solar cells, the effect of magnetic nanoparticles on the P3HT:PCBM films as the active layer and the properties of polymer solar cells under the external magnetic field were investigated. The Fe3O4 magnetic nanoparticles were prepared by thermal decomposition. The Fe3O4 nanoparticles of different mass fraction were added to P3HT:PCBM solution.The as-casting films by spin coating method were put into the external magnetic field and the self-assembled Fe3O4+P3HT:PCBM films were formed. Fe3O4 nanoparticles were characterized by TEM and XRD, and the surface morphology of films was investigated by polarizing microscope(POM) and atomic force microscope(AFM). The results show that Fe3O4 nanoparticles are about 10 nm in diameter, and have a certain regulating effect on building film of P3HT:PCBM. When Fe3O4 nanoparticles are added with a mass fraction 1%, the open circuit voltage(Voc) of the solar cells increases by 3.77%, the short-circuit current(Ist) increases by 24.93%, and the photoelectric conversion efficiency(PCE) increases by 7.82%. © 2018, Science Press.
