The development of low-cost, lightweight, and flexible energy harvesting and storage devices are an enabling technology for many different applications.  A variety of different nanostructured electrode architectures are being developed to improve their performance and will be discussed.  These include a nano-templating methodology based on porous anodic alumina in order to fabricate vertically aligned titania nanotubes of controllable shape and size, and vertically aligned carbon nanotubes for use as either intercalation (in batteries) or charge collecting (in PVs) electrodes.  In addition, efforts to understand and tune the device spectral response will be discussed.  By utilizing an interfacial modification technique based on layer-by-layer deposition, nanoparticle surfaces have been functionalized with electronically active species and integrated into device structures.  Finally, efforts focused on the development of hybrid electrodes fabricated via atomic layer deposition for high energy density and rate capability batteries will be described.
