Effective enhancement of the performance of black dye based dye-sensitized solar cells by metal oxide surface modification of the TiO2 photoelectrode.
نویسندگان
چکیده
Effective enhancement of the performance of black dye based dye-sensitized solar cells has been achieved by MgO or Al(2)O(3) surface modification of the TiO(2) photoelectrode. The conversion efficiency was improved from 10.4% to 10.8% due to the blocking effect of the thin overlayer at the TiO(2) surface.

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...
متن کاملLight scattering with oxide nanocrystallite aggregates for dye- sensitized solar cell application
Oxide nanocrystallite aggregates are candidates for use in dye-sensitized solar cells. The aggregates are of submicron size, formed by nano-sized crystallites and, therefore, able to offer both a large specific surface area and desirable size comparable to the wavelength of light. While used for a photoelectrode in a dye-sensitized solar cell, the aggregates can be designed to generate effectiv...
متن کاملFabrication of Novel High Potential Chromium-Doped TiO2 Nanoparticulate Electrode-based Dye-Sensitized Solar Cell (DSSC)
In the current study, pure TiO2 and Cr-doped TiO2 (Cr@TiO2) nanoparticles were synthesized via sol-gel method and the resulting materials were applied to prepare the porous TiO2 electrodes for dye-sensitized solar cells (DSSCs). It is hypothesized that the advantages of the doping of the metal ions into TiO2 lattice are the temporary rapping of the photogenerated electron-hole (charge carriers)...
متن کاملNatural dyes extracted from black carrot and bramble for Dye-Sensitized Solar Cells
Two different natural dyes containing anthocyanin extracted from black carrot and bramble from Iran. Spectrophotometric evaluations of the natural dyes in solution and on a TiO2 substrate were carried out in order to assess changes in the status of the natural dyes. The results show that the natural dyes indicate buthochromic shift on the TiO2 substrates. The chemical adsorption of natural dyes...
متن کاملEffects of Sensitization with Natural Pigments on the Performance of Dye-sensitized Solar Cell (DSSC)
Three natural pigments including wild iris, black pomegranate bark and black grapes were used as sensitizer in dye sensitized solar cells (DSSCs) based on TiO2 nanoparticles. The results showed that the DSSC made of black pomegranate bark was more efficient than the other cells due to its strong bonding with TiO2 nanoparticles. Longer electron lifetime, lower electron recombination, and lower...
