Effect of Solvents on Mixture of Azur B and Sudan Black B Photosensitizer in Fabrication of DSSC
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 1
Abstract
The photoelectrodes of thin film of dye sensitized solar cells (DSSC) are generally fabricated from TiO2 nanoparticles paste, above which dye is adsorbed. The aim of this paper is to study the influence of mixing different photosensitizer in different solvents on cell performance. To this end, identical method and materials except the photosensitizer will be used. Three sets of organic dyes (photosensitizer) with different solvent are prepared; Sudan Black B and Azur B are firstly examined and obtained results compared with the results of mixture of same dyes in distilled water, ethanol and dimethyl sulphoxide (DMSO) solvents. The effects of photosensitizer are studied because they play a major and foremost role in working of DSSC. Fully operating DSSC thus manufactured using mixture of organic dyes as sensitizer, an electrolyte and a counter electrode. Their photo-energy conversion efficiency has been measured in environmental conditions. High efficiencies for mixture of dyes are obtained when compared to results of their individual dyes, thus, showing the influence of mixture of dyes. Although the mixture of many other dyes not necessarily will increase the cell performance, sometimes other parameters of DSSC may affect the performance of cell.
