Interaction of Sensitizing Dyes with Nanostructured TiO2 Film in Dye-Sensitized Solar Cells Using Terahertz Spectroscopy

The objective of this investigation was to shed light on the nature of interaction of different organic dyes and an inorganic dye, Ruthenium (II) polypyridine complex, with TiO2 nanoparticles. TiO2 is commonly deployed as an efficient energy transfer electrode in dye sensitized solar cells. The efficiency of dye sensitized solar cells is a function of the interaction of a dye with the electrode...

Photoinduced absorption spectroscopy of dye-sensitized nanostructured TiO2

Photoinduced absorption (PIA) spectroscopy was used to investigate dye-sensitized electrodes and solar cells under illumination conditions comparable to sunlight. In the absence of redox electrolyte, cis-RuðdcbpyÞ2ðNCSÞ2-sensitized nanostructured TiO2 films show a long-lived photoinduced charge-separation (oxidized dye molecules/injected electrons in TiO2), with a lifetime of about 10 3 s under...

Influence of nanostructured TiO2 film thickness on photoelectrode structure and performance of flexible Dye- Sensitized Solar Cells

A  commercial  Ti-Nanoxide  was  deposited  on  In-doped  SnO2 (ITO) polymer  substrates by  tape casting  technique with different thicknesses  (7,  14  and  36μm)  to  be  used  as  photoelectrode  in flexible  dye-sensitized  solar  cells  (DSSCs).  Ruthenium  dye  was adsorbed on each TiO2 film for 24 h. The resulting photoelectrodes were used to form flexible DSSCs in combination with...
