基于有机的光转换器受到相当大的兴趣，由于其有前途的功能和它们的潜在用途作为更昂贵的无机类似物的替代品。我们介绍了基本的操作机制，限制和一些想法对提高效率的有机太阳能电池的形态/结构，动力学，和电子方面的电荷转移dissolved液晶系统六（正己氧基）苯并菲/2，4，7三硝基-9-芴酮（HAT 6/TNF）组成的模型有机材料的重点探测。在电子基态研究中，中子散射技术在深入了解结构和动力学方面发挥着关键作用。这些测量是由拉曼和核磁共振探针，以及共振拉曼和紫外-可见光谱，用于探索低位激发态，在电子振动水平的补充。协同，数值模拟，无论是经典的经验力场，或通过密度泛函理论的第一原理，用于分析，解释和预测。
Organic-based photoconverters are subject to a considerable interest due to their promising functionalities and their potential use as alternatives to the more expensive inorganic analogues. We introduce the basic operational mechanisms, limitations and some ideas towards improving the efficiency of organic solar cells by focusing on probing the morphological/structural, dynamical, and electronic aspects of a model organic material consisting of charge-transfer discotic liquid-crystal system hexakis(n-hexyloxy)triphenylene/2,4,7 trinitro-9-fluorenone (HAT6/TNF). For the electronic ground-state investigations, neutron-scattering techniques play a key role in gaining deeper insight into structure and dynamics. These measurements are complemented by Raman and nuclear magnetic resonance probes, as well as resonant Raman and UV-vis spectroscopies that are used to explore the low-lying excited states, at the vibronic level. Synergistically, numerical simulations, either classical via empirical force fields, or first-principles via density functional theory, are used for the analysis, interpretation and predictions.
