Dye-sensitized solar cells using some organic dyes as photosensitizers

Eight organic dyes are used as sensitizers for dye-sensitized solar cells. These dyes are eosin Y, aniline blue, bromophenol blue, alcian blue, methyl orange, crystal violet, fast green, and carbol fuchsin. The absorption spectra of these dyes are carried out by UV–VIS spectrophotometry. Dye-sensitized solar cells are assembled using nanostructured, mesoporous TiO2 films. Photovoltaic parameters of the fabricated cells are investigated and the highest overall conversion efficiency of 0.399% is obtained for the dye-sensitized solar cell sensitized with eosin Y.
