The Taguchi method was adopted to determine the optimal gel electrolyte used in dye-sensitized solar cells (DSSCs). Since electrolyte is a very important factor in fabrication of high performance and long-term stability DSSCs, to find the optimal composition of gel electrolyte is desired. In this paper, the common ingredients used in the liquid electrolyte were chosen. The ingredients then mixed with cheap ionic liquids and poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) were added to form colloidal electrolyte (gel). The optimal composition of each materials in the gel electrolyte determined by Taguchi method consists of 0.03 M I2, 0.15 M KI, 0.6 M LiI, 0.5 M 4-tertbutylpyridine (TBP), and 10% PVDF-HFP dissolved in the acetonitrile and 3-methoxypropionitrile (MPN) solution with volume ratio of 2 : 1. The short circuit current density of 14.11 mA/cm2, the conversion efficiency (η) of 5.52%, and the lifetime of over 110 days were observed for the dye-sensitized solar cell assembled with optimal gel electrolyte. The lifetime increases 10 times when compared with the conventional dye-sensitized solar cell assembled with liquid electrolyte.

Electrolyte is one of the crucial elements in dye sensitized solar cells (DSC) due to the reduction-oxidation reactions take place in this area and it has the function as the charge transfer medium. An electrolyte solution contains redox couple such as I-/I3 is filled up into a space between the photo-anodes and the counter electrode. Usually, the DSC employs a liquid electrolyte which using organic solution because easy preparation. But it has disadvantage, solvent evaporation occurs and this can decrease the cell performance. One of way to solve this problem is change liquid electrolyte to gel electrolyte. This paper describes fabrication of DSC based on gel electrolyte. Performance of the DSC is compared to the cell which using a liquid electrolyte. The result shows that the energy conversion efficiency of the solar cells based on gel electrolyte was lower than liquid electrolyte solar cell that is 1.51% and 2.23% respectively. Based on life time investigation obtained the performance of gel electrolyte solar cell is much stable than liquid electrolyte solar cell.

AbstractThis article presents the results of a research on the effects and properties of the potassium iodide additive onto the structure of the MEH-PPV polymer material, in its aspect of application in the dye-sensitized solar cell. Changes in MEH-PPV surface morphology were researched through increasing of the potassium iodide content measured by scanning electron microscope. The increased content of potassium iodide also led to increased electrical conductivity measured by the Keithley meter. The electrical properties of the dye-sensitized solar cell were also studied, in which the liquid electrolyte was replaced with a thin layer of polyelectrolyte, based on MEH-PPV and potassium iodide.
