Pt Deposition on Anode Enhances the Performance of Dye-Sensitized Solar Cell with Non-Cross-Linked Gel Electrolyte

Abstract

We fabricated dye-sensitized solar cells with non-cross-linked fluorinated gel electrolyte. The application of fluorinated gel to electrolyte is a challenging issue at present. The gelation of the electrolyte is of importance in order to solve the problem in the durability of the cell. We investigated, in this article, the effect of Pt deposition on the anode of the cell. The Pt was deposited by means of a DC sputtering technique. The studies showed that the deposition time strongly affected both open voltage and short-circuit current of the cell. The adaptive thickness of the Pt layer was determined to be 10 nm for the non-cross-linked fluorinated gel electrolyte cells.

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

“…It was then cooled down to room temperature naturally and soaked in a Ruthenium complex dye diluted with ethanol at 3 × 10 4 mol/l at 50˚C for 24 hours. Onto another FTO glass substrate for an anode, Pt was slightly deposited by a sputtering method for 3 minutes as was reported before [9].…”

“…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].…”

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

“…Second, the anode was prepared in such a way that Pt was deposited on FTO glass by a DC sputtering apparatus. The sputtering time was 3 minutes and 10-nm thick Pt film was obtained [8].…”

“…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.…”
