Abstract/Summary:


The effects of dye purification on the initial performance and lifetime of dye-sensitized solar cells are studied. The use of UV filters to prevent electrolyte bleaching (the loss of tri-iodide in the electrolyte) during light soaking tests is also investigated. The initial performance and stability were characterized with IV tests, electrical impedance spectroscopy and cell photographing. Statistical methods were applied in the result analysis to increase the reliability of the results. Dye purification did not have statistically significant effect neither on the cell performance nor lifetime in this study. UV filtering did reduce electrolyte bleaching but did not completely prevent it.
