Carbon nanotubes are a one-dimensional nanostructured allotropic form of carbon and exhibit high carrier mobility and unique ballistic conduction pathways.  It has been suggested to replace fullerene by nanotubes in the polymer solar cells to enhance the device performance. Typically, the nanotube-based polymer solar cells demonstrate the poor device performance with a power conversion efficiency below 1%. Recent studies have shown that interfacial interactions between conjugated polymers and nanotubes are pivotal in determining the device performance. However, the dynamic process of such interactions is largely unknown. Here, we report on interfacial structures and crystallization kinetics of poly(3-hexylthiophene) with single-walled carbon nanotubes in anisole by means of transmission electron microscope and ultraviolet-visible absorption spectroscopy. <br/><br/>
