Dye-Sensitized Solar Cell with Fluorinated Gel Electrolyte: Effect of TiO<sub>2</sub> Particle Size on Performance

Abstract

We fabricated dye-sensitized solar cells including fluorinated gel electrolyte and studied about the relationship between the performance of the solar cells and the aggregation state of TiO 2 nano-particles on electrodes. As for the performance of the cell, the I-V characteristics were measured under irradiation. The combination of TiO 2 nanoparticles with different size plays an important role in bringing unevenness to realize a large surface area, which is critical for the high performance of the cells.

Addition of Pyridine to Dye-Sensitized Solar Cell Including Fluorinated Oligomer Gel Electrolyte

“…We have been studying various aspects of the solar cell with the fluorinated oligomer gel electrolyte. The issues investigated so far are, for example, the TiO 2 particle [7], the Pt layer on the anode [8], LiI effect instead of I 2 [9], and the introduction of ionic liquids [10], In this article, the addition of pyridine to the electrolyte is considered. Pyridine complex derivatives have been introduced to enhance the cell performance.…”

Electric Conductivity of Fluorinated Oligomer Gel Electrolyte Including Ionic Liquid and Performance of Dye Sensitized Solar Cell

“…The experimental conditions such as the TiO 2 layer on the cathode [8], the amount of Pt sputtering deposition on the anode [9], and LiI concentration in the gel electrolyte [10]. The introduction of ionic liquid has been also considered [11].…”
