A Performance Comparison of Dye-Sensitized Solar Cells Based on Mesoporous and Nanostructured Photoanodes
نویسندگان
چکیده
A comparison has been drawn in pure anatase and rutile forms of TiO2 films with their respective nano crystalline forms as photoanodes in dye-sensitized solar cells. All the films have been synthesized by using sol-gel method. Crystalline nature of the films has been investigated by x-ray diffraction (XRD) and morphologies have been studied by scanning electron microscopy (SEM). The short-circuit current density (JSC) for anatase based cell is about 30% higher than that of rutile based cell. Efficiency values obtained for nano anatase and rutile based DSSCs are 6.6% and 4.8% respectively. The results have been further approved by diffusion coefficient studies which reveal that rutile film has a poor diffusion coefficient than anatase film.

Application of azo dye as sensitizer in dye-sensitized solar cells
An azo dye used as photosensitizers in Dye-sensitized solar cells DSSCs. Azo dyes economically superior to organometallic dyes because they are color variation and cheap. The spectrophotometric evaluation of an azo dye in solution and on a TiO2 substrate show that the dye form J-aggregation on the nanostructured TiO2 substrate. Oxidation potential measurements for used azo dyes ensured an energ...
