摘要
为了提高太阳能电池的性能,研究磁性纳米粒子在外加磁场的作用下对聚合物太阳能电池有源层P3HT∶PCBM成膜及太阳能电池性能的影响。本文采用热分解法制备了磁性Fe_3O_4纳米粒子,将不同质量分数的Fe_3O_4纳米粒子掺入到P3HT∶PCBM溶液中,旋涂后在外加磁场的作用下自组成膜。通过TEM、XRD对制备的Fe_3O_4纳米粒子进行表征,并利用偏光显微镜、原子力显微镜对成膜质量进行探究。结果表明,采用热分解法制备的Fe_3O_4纳米粒子直径在10 nm左右,在外加磁场作用下,Fe_3O_4纳米粒子对成膜有一定的调控作用。当Fe_3O_4纳米粒子掺杂质量分数为1%时,太阳能电池器件的开路电压增加3.77%,短路电流增加24.93%,光电转换效率提高7.82%。
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 Fe 3O 4 magnetic nanoparticles were prepared by thermal decomposition.The Fe 3O 4 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 Fe 3O 4+P3HT∶PCBM films were formed.Fe 3O 4 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 Fe 3O 4 nanoparticles are about 10 nm in diameter,and have a certain regulating effect on building film of P3HT∶PCBM.When Fe 3O 4 nanoparticles are added with a mass fraction 1%,the open circuit voltage(V oc)of the solar cells increases by 3.77%,the short-circuit current(I st)increases by 24.93%,and the photoelectric conversion efficiency(PCE)increases by 7.82%.
