  • Hot-wire chemical vapour deposition of carbon Nanotubes 

    Cummings, Franscious Riccardo (University of the Western Cape, 2006)
    In this study we report on the effect of the deposition parameters on the morphology and structural properties of CNTs, synthesized by means of the hot-wire chemical vapour deposition technique. SEM, Raman and XRD results ...

  • TiO2 nanotube based dye- sensitised solar cells 

    Cummings, Franscious Riccardo (University of Western Cape, 2012)
    This work investigated the synthesis of Al2O3-coated TiO2 nanotubes via the anodisation technique for application in DSCs. TiO2 nanotube arrays with an average length of 15 μm, diameter of 50 nm and wall thickness of 15 ...

  • TiO₂ nanotube based dye-sensitised solar cells 

    Cummings, Franscious Riccardo (University of the Western Cape, 2012)
    The first report of a functioning photo-electrochemical solar cell in 1991 attracted a lot of interest from scientists and industrial groups. From an industrial point of view these so-called dye-sensitised solar cells ...
