Up to now the efficiencies of organic solar cells cannot compete with conventional semiconductor photovoltaics. One major challenge is the control of the interfacial area between donor-acceptor materials. In this project, the synthesis and design of organic materials that phase separate spontaneously and a novel template deposition method on conducting glass substrates will enable supramolecular to nanometer scale ordering. Advanced scattering experiments such as grazing incidence wide- and small-angle X-ray scattering will give full details about the installed nanostructure. This full control and knowledge about the structure will allow us a systematic investigation of the dependence of device performance on the thin film morphology. The electrical properties of the active materials will be probed with high resolution scanning probe techniques such as Kelvin force microscopy and conductive scanning probe microscopy. Deeper understanding of the device physics and underlying optoelectronic processes in connection to the interface morphology will help to find the ideal organic solar cell structure.

到目前为止，有机太阳能电池的效率还不能与传统的半导体光电转换器竞争。一个主要的挑战是供体-受体材料之间的界面面积的控制。在这个项目中，自发相分离的有机材料的合成和设计以及在导电玻璃基底上的新型模板沉积方法将使超分子到纳米尺度有序化成为可能。先进的散射实验，如掠入射宽角和小角X射线散射，将提供有关安装的纳米结构的全部细节。这种全面的控制和知识的结构将使我们能够系统地调查薄膜形态的器件性能的依赖。活性材料的电性能将探测高分辨率扫描探针技术，如开尔文力显微镜和导电扫描探针显微镜。深入了解器件物理和与界面形态相关的潜在光电过程将有助于找到理想的有机太阳能电池结构。
