Yumbo Tumtum as a Photosensitizer in the Fabrication of a Dye-Sensitized Solar Cell
Abstract:A dye-sensitized solar cell (DSSC) was fabricated using a natural dye Yombo-tumtum (YT) as the photosensitizer. The solar cell configuration include a transparent conducting oxide (TCO) (Fluorine-doped tin oxide coated glass or FTO/glass) substrate as the transparent electrode, Zinc oxide (ZnO) as anode, YT as the sensitizer, iodide/triiodide (I − /I3 − ) as the electrolyte, and platinum coated FTO/glass as counter electrode (cathode). The absorption spectrum of the dye (YT) was investigated by uv/vis spectros… Show more
