Neutron scattering techniques provide unique insights into the active layer morphology of organic solar cells. The nanoscale morphology, the thin film vertical composition, and the intermixing on a molecular level, which all strongly have an impact on the performance of organic solar cells, can be probed with neutrons. In addition to the static structure, also fast dynamics occurring in the active material is accessible with neutrons. This perspective letter highlights the power of grazing incidence small angle neutron scattering and quasi-elastic neutron scattering experiments after shortly introducing into the working principle of organic solar cells.

用先进的中子散射技术探测有机太阳能电池

中子散射技术为有机太阳能电池的活性层形态提供了独特的见解。可以用中子探测纳米级形态、薄膜垂直组成和分子水平上的混合，这些都对有机太阳能电池的性能产生强烈影响。除了静态结构外，活性材料中发生的快速动力学也可通过中子获得。这封透视信在简要介绍了有机太阳能电池的工作原理后，重点介绍了掠入射小角中子散射和准弹性中子散射实验的威力。
