The proposed renewal project is based on a very fruitful cooperation between the three groups in the last 2 years supported by SPP 1355 program. The results of photovoltaic performance investigation of thiophene dendrimer-based BHJ solar cells as well as morphology analysis and modeling on P3HT:ZnO solid films, obtained so far, serve as a basis for the continuation of the project. In this renewal proposal, the objective of this interdisciplinary research project is to develop novel three dimensional conjugated oligothiophene dendrimers as organic semiconductors for applications in solution-processed bulk-heterojunction solar cells, and utilize these three dimensional monodisperse organic nano-objects as model compounds to investigate the elementary physical processes in bulk heterojunction solar cells. In particular, the understanding of the role of nanoscale phase on device performance, including charge generation, transportation and collection will be addressed in detail. Nanoscale phase separation of dendrimer:PCBM or dendrimer:ZnO blended films will be investigated by microscopic technologies, such as scanning probe and transmission electron tomography. Mathematical models will be developed for analyzing, describing, and simulating the morphology of the blended films. Furthermore, solar cell device models that describe absorption of light, diffusion of excitons, charge generation and charge transport within disordered nanoscale bulk heterojunction blends of donor and acceptor materials will be developed and used to describe and understand the performance of oligothiophene dendrimer solar cells.

拟议的续约项目基于在过去两年中由SPP 1355计划支持的三组之间的非常富有成果的合作。迄今为止获得的P3HT：ZnO固体膜对基于噻吩的树枝状聚合物BHJ太阳能电池的光伏性能研究以及形态分析和建模的结果，是该项目继续进行的基础。在该更新建议中，该跨学科研究项目的目的是开发新型的三维共轭寡噻吩树突聚合物作为有机半导体，以应用于解决方案处理的体积正形和实质性太阳能细胞，并利用这三个维度的物质纳米型型型号的元素混合物，并利用这三个维度的元素。太阳能电池。特别是，将详细介绍对纳米级阶段对设备性能的作用（包括收费，运输和收集）的作用的理解。树枝状聚合物的纳米级相分离：PCBM或树枝状聚合物：ZnO混合膜将通过微观技术（例如扫描探针和透射电子层析成像）进行研究。数学模型将开发用于分析，描述和模拟混合膜的形态。此外，将开发并使用太阳能电池设备模型来描述供体和受体材料的纳米级散装异质结的混合物中的含量，电荷的产生和电荷转运，并用来描述和理解寡硫酸基因树状元素元素太阳能细胞的性能。
