Analysis of Different Thicknesses of Electrolyte Applied in Flexible Dye - sensitized Solar Cells

In this study, the different electrolyte thicknesses were investigated with various quantities of space layers, which were applied in the flexible dye-sensitized solar cells. The different materials of space layers were Surlyn film and Teflon tape. The thicknesses of Surlyn and Teflon tape were 60 μm, and 46.72 μm, respectively. The thickness of TiO2 layer is 8.25 μm. According to the experiment for different thicknesses and layers of Surlyn and Teflon tapes, and then the thickness of space layer subtracts the thickness of TiO2 layer will get the thickness of electrolyte, so the flexible dye-sensitized solar cells will have different thicknesses of electrolyte. The active area of flexible dye-sensitized solar cell was 0.8 cm × 0.8 cm, and the area of space layer of flexible dye-sensitized solar cell was 1.2 cm × 1.2 cm without hollow area 0.8 cm × 0.8 cm. According to the experimental results, the Surlyn of 3 layers has the best characteristic parameters and conversion efficiency, the open circuit voltage is 0.72 V, where the short This study has been supported by National Science Council, Republic of China, under the contracts NSC 101-2221-E-224-046, NSC 101-2221-E-265-001, NSC 100-2221-E-224-017 and NSC 100-2221-E268-004.
