Nanostructured Photo-Electrochemical Materials
with private browsing in FireFox
Photo-electrochemical materials harness solar energy to drive electrochemical reactions. Such materials and processes could be the basis for economical, large-scale future technologies for harvesting solar energy, producing renewable fuels and chemicals, and decontaminating water. I will describe approaches for creating efficient photo-electrochemical materials by controlling their shape, size and composition at the nanoscale, in a manner that balances light absorption, charge transport, and surface reaction processes. In addition, I will present optoelectronic and electrochemical characterization methods used to better understand each of these processes. Two examples of nanostructured photo-electrodes will be described to illustrate these approaches – the first based on bismuth vanadium oxide (BiVO4) coated onto various nanostructured metal oxides, and the second based on vertical nanoflakes of tin disulfide (SnS2). Finally, I will also describe new work on photodetectors based on vertical SnS2 nanoflakes sensitized by lead sulfide quantum dots, and a recently-started project on inkjet printing of flexible hybrid electronics.
