Polymeric nanoparticles dispersed in an aqueous medium were synthesized using the miniemulsion technique. In this study, nanoparticles composed of copolymer F8T2, homopolymer MDMO-PPV and a mixture of both were investigated aiming to unravel the interaction between these materials. By decreasing the distance between the nanostructured materials, higher Förster resonance energy transfer (FRET) was observed from F8T2 to MDMO-PPV. This enhanced energy transfer could generate more free charge carriers, increasing the short circuit current density, when the nanoparticles were applied as an active layer in organic photovoltaic devices, influencing the increase in the efficiency of these devices.

用于光伏应用的水性分散聚合物纳米颗粒中的非辐射能量转移

使用细乳液技术合成了分散在水性介质中的聚合物纳米颗粒。在这项研究中,研究了由共聚物F8T2,均聚物MDMO-PPV和两者的混合物组成的纳米粒子,旨在揭示这些材料之间的相互作用。通过减小纳米结构材料之间的距离,可以观察到从F8T2到MDMO-PPV的更高的Förster共振能量转移(FRET)。当将纳米颗粒用作有机光伏器件中的活性层时,这种增强的能量传递可以生成更多的自由电荷载流子,从而增加短路电流密度,从而影响这些器件的效率提高。
