Controlling the morphology of materials with domain size on the nanometer scale is critically important when considering the function of materials, for example in sensing, display, and energy applications.  Our work centers on improved performance of thin film polymer photovoltaic devices, achieved by assembling p- and n-type nanoscale materials in a dense, alternating, parallel fashion.  This presentation will describe the assembly of P3HT into nanowires, in which functionality placed at the polymer chain-end translates into sticky sides on the nanowires.  These functional nanowires are thus suitable for coordination to n-type inorganic semiconductors, such as CdSe nanorods. The synthesis and assembly process, as well as the integration of these novel materials into the active layer of solar cells, will be discussed.
