Hybrid Inorganic/Organic Photovoltaics: Translating Fundamental Nanostructure Research to Enhanced Solar Conversion Efficiency

摘要

Improving the efficiency of organic photovoltaics through material and device design innovations is a prolific field in alternative energy research. The purpose of our research is to develop key concepts that will enable new design criteria for organic photovoltaic (PV) cells based on polymeric nanocomposites, which are expected to produce large enhancement in power conversion efficiency. In this report for the third and final year we report the microstructure tuning of nanoparticle films by making them photopatternable, development of fullerene derivatives which are highly efficient n-type semiconductor, design and synthesis of low bandgap polymers, the improvement of solar cells by local surface plasmon resonance enhancement of light, and achieving higher efficiency in quatumn dot (QD)-polymer solar cells by ligand exchange of QD ligands.
