Debundling and Selective Enrichment of SWNTs for Applications in Dye-Sensitized Solar Cells
Figure 1
Schematic representation of the structure of a dye sensitized solar cell. The cell has 3 primary parts. On the top is a transparent photoanode made of Indium-doped tin oxide (ITO) deposited on the back of a transparent glass. On the back of the conductive plate is a layer of titanium dioxide (), which forms into a highly porous structure with an extremely high surface area (green beads). A thin layer of a photosensitive ruthenium-polypyridinedye (purple beads) [55] is covalently bonded to the surface of the . A separate backing is made with a thin layer of the iodide electrolyte () spread over a conductive sheet, typically platinum metal (the counter electrode). The front and back parts are then joined and sealed together to prevent the electrolyte from leaking.
