Abstract：
Solar cell devices and systems based on appropriately designed and fabricated nanostructures and nanomaterials have been demonstrated to exhibit good optoelectric conversion performances in recent years. The large specific surface area and short diffusion distance can surely enhance the interface and transport kinetics, while the surface energy and defects will impact the phase transition and reaction thermodynamics. In this presentation, I will illustrate how optoelectric conversion efficiency can be significantly improved through careful design and engineering of material interfaces on the nanometer and micrometer scales and through surface chemistry modification. I will discuss the nanostructured photoanodes for dye-sensitized solar cells, quantum dot-sensitized solar cells and inverted polymer solar cells, and the impacts of interface (including surface chemistry and morphology) on the power conversion efficiency.
