fa Investigation of Presence an Anti-aggregation Agent on Performance of Dye Sensitized Solar Cells Based on Indigo تخصصی Special پژوهشي Research Indigo dyes for high technical properties are suitable for application in dye-sensitized solar cell. The defect of these components is their aggregation on TiO2 substrate. The wavelength of maximum absorption for selective dye in the presence and absence of anti-aggregation agent are 559 nm and 568.5 nm, respectively. The wavelength of maximum absorption in solvent is 548.5 nm. The reduction of bathochromic effect leads to reduce aggregation dye. The conversion efficiency in the presence and absence of anti-aggregation agent are 3.45% and 3.11%, respectively, that the presence of anti-aggregation agent was improved the conversion efficiency of solar cell.
