Spectroscopic Evaluation of Mixing and Crystallinity of Fullerenes in Bulk Heterojunctions

The microstructure of blend films of conjugated polymer and fullerene, especially the degree of mixing and crystallization, impacts the performance of organic photovoltaic devices considerably. Mixing and crystallization affect device performance in different ways. These phenomena are not easy to sc...
