“…We then added 2-acrylamid-2-methyl-propanesulfonic acid (AM-PS) to this solution and mixed for 200 minutes further. The AMPS is one of fluorinated oligomers [9] that has the structure shown in Figure 1. The amount of AMPS added for gelation should be roughly larger than 330 g/l; the critical gelation density that was obtained experimentally.…”

“…Some researchers have been challenging with the cross-linking of a polymer [8]. We have been engaged on the other hand in the application of fluorinated gel electrolytes that have already been proposed to apply to a secondary battery [9]. The fluorinated gel electrolyte is cohesively derived from intermolecular force between the fluorinated alkyl groups and ionic bonding at the same time.…”

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.

Fluorinated oligomer gel is suitable to the electrolyte of dye sensitized solar cell. This article studied mainly in the scope of electric conductivity, including ionic liquid in the electrolyte. It was found that the ratio of mixing with dimetyl sulfoxide and the concentration of LiI affect the conductivity. The behavior is different depending on the type of ionic liquid. Although the mixing ionic liquid enhances the conductivity, the short circuit current density of assembled solar cell with it was suppressed so much.

“…Some researchers introduced an electrolyte of a polymer cross linked by a chemical reaction to be like a net holding an electrolyte [5]. Our group have developed fluorinated oligomer gel electrolyte for a second ion battery [6], which has been applied to dye-sensitized solar cell afterwards. The advantage of the fluorinated oligomer gel electrolyte is self-aggregation property without cross linkage between chains.…”

Fluorinated oligomer gel is suitable to the electrolyte of dye-sensitized solar cell for low cost production. In this article, addition of pyridine was investigated for the purpose of enhancing the short current density. Two kinds of ionic liquids were tested: imidazolium and pyrazolium systems. The two different stages of adding pyridine to the electrolyte were considered and the amount of pyridine was studied. It was found that the electrolyte including pyrazolium ionic liquids to which pyridine was added before the mixing with fluorinated oligomer showed the highest electric conductivity, short current density and open voltage. This resulted in the highest conversion efficiency of 4%. As the amount of pyridine increased, the fill factor and the open voltage were improved at first, and then the short current density increased. If the pyridine was added more, the short current density conversely decreased.
