By a News Reporter-Staff News Editor at Energy Weekly News -- Current study results on Solar Energy have been published. According to news reporting out of Turin, Italy, by VerticalNews editors, research stated, "The fabrication and characterization of TiO2 nanotube (NT) arrays and their integration in front-side illuminated Dye-sensitized Solar Cells (DSCs) are reported. Vertically oriented TiO2 NTs were obtained by anodic oxidation of titanium foil and not-curling free-standing NT membranes were easily separated from the metal without the formation of cracks."
Our news journalists obtained a quote from the research from Technical University, "Stoichiometry, crystalline phase and morphology of the films were investigated, evidencing the formation of a highly ordered 1D NT array, with a pure anatase crystalline structure. Transparent photoanodes were fabricated transferring the membranes on FTO/glass sheet with an adhesion layer made of TiO2 nanoparticle (NP). What makes this work different from others reported in literature is the easiness of the technological approach: no mechanical or chemical etchings are required for NT membrane detachment and only one thermal step is needed for NT crystallization and TiO2 NPs/NTs interface formation. TiO2 NT-based DSCs were fabricated using a reversible microfluidic architecture and the cells were characterized by I-V electrical measurements, incident-photon-to-electron conversion efficiency, open circuit voltage decay and impedance spectroscopy."
According to the news editors, the research concluded: "Compared to the standard NP-based DSC, the TiO2 NT-based one shows a huge increase of the transport properties and a consequent improvement in cell performances."
