Understanding charge separation processes and developing materials that can efficiently direct photogenerated carriers with nanoscale precision are of fundamental importance in advancing next- generation dean energy technologies. In particular, one-dimensional semiconductors with their inherent shape anisotropy provide promising platforms. In this talk, I will discuss colloidal nanorod heterostructures of II-VI semiconductors as examples of solution-processable heterojunction nanostructures. Challenges in materials synthesis, unusual lattice strain at interfaces, and some initial results from photovoltaic and transient absorption measurements will be presented.
