- a heat treatment was performed in the air at 500 ° C for 30 minutes, and after cooling to form a titanium film of about 10 mm, the film was immediately immersed in an ethanol solution of a ruthenium complex.
- a ruthenium complex which is a sensitizing dye, was adsorbed on the titanium oxide fine particles constituting the film, and a dye-sensitized semiconductor electrode was formed.
- Iodine electrolyte 3 was impregnated on the dye-sensitized semiconductor electrode.
- Iodine electrolyte 3 For this, a solution prepared by dissolving tetrapropylammonium-moxide and iodine in a mixed solution of ethylene carbonate and acetonitrile was used.
- the glass substrate on which the carbon thin film was deposited and the glass substrate on which the dye-sensitized semiconductor electrode to which iodine was dropped were formed were overlapped.
- an I-seal cooled to 120 ° C is applied and sealed with a dispenser, and the I-seal is cured in the course of cooling, and the superposed substrate is cured.
- the dye-sensitized solar cell was fixed and fabricated.
- two substrates having two holes (flmm) 8 formed on one substrate are superimposed, and two I-seals heated to 100 ° C. are placed around the two superposed substrates. After coating around the substrate, it was baked at 300 ° C to cure the I-seal. After cooling, a ruthenium complex as a sensitizing dye was injected from one hole and allowed to adhere to the titanium oxide fine particles. Next, in the same manner, after injecting the iodine electrolyte from one hole 8, the two holes are heated to 300 ° C, and then cooled to 120 ° C, and an I-seal is applied using a dispenser. It was cured and sealed in the process of cooling to produce a dye-sensitized solar cell.
- Figure 4 shows a schematic cross-sectional view
- Figure 5 shows a process flow diagram.
- an I-seal heated to 100 ° C was applied to the periphery of the two substrates before the two substrates having two holes (flmm) 8 formed on one substrate were superimposed.
- the substrates were bonded together and baked at 300 ° C to cure the I-seal.
- a sensitizing dye ruthenium complex was injected from one hole 8 and allowed to adhere to the titanium oxide fine particles.
- the two holes were heated to 300 ° C, and then cooled to 120 ° C, and an I-seal was applied using a dispenser.
- hard sealing and sealing A sensitized solar cell was fabricated (not shown).
