- a 10% solution of titanium tetrabutoxide (Brimer) was applied to the outer periphery of the product obtained in 3.2 and dried, and the sealant composition was applied in a ring along the outer periphery. A portion of the annular bead was removed to provide a filling port for filling the electrolyte.
- a transparent conductive glass plate coated with fluorine-doped tin oxide and further supporting platinum thereon was prepared, and the primer was applied to the outer periphery thereof. This Using a spacer as a pole, the laminate was coated with the above-mentioned sealant composition applied thereto. This was heated at 120 ° C. for 40 minutes to cure the sealant composition.
- An electrolyte was inserted between the two electrodes from the inlet, and the inlet was sealed with a room-temperature curable resin, and then a lead wire was attached to produce a dye-sensitive solar cell.
- tetrapropylammonium-piumiodide and iodine were added to a mixed solvent of acetonitrile / ethylene carbonate having a volume ratio of 1: 4, and the concentrations thereof were 0.46 molno 1 and 0.06 mol1, respectively. What was melt
- the obtained solar cell was heated in a heating furnace at 100 ° C. for 1 hour, and a change in weight was measured as a durability test. As a result, there was no change and no electrolyte leaked.
- a solar cell was similarly manufactured using a conventional sealing agent.
- an epoxy-modified silicone (trade name: Three Bond 3950 manufactured by Sri Bond Co., Ltd.)
- a solar cell was manufactured at 25 ° C. ⁇ 55% RH for 7 days under curing conditions.
- a solar cell was manufactured by irradiating ultraviolet rays using an ultraviolet-curable acryl resin (trade name: Three Bond 305 1 manufactured by Three Bond Co., Ltd.). Both were similarly heated in a heating furnace at 100 ° C for 1 hour, and the change in weight was measured.The former decreased by 2% and the latter decreased by 0.15%. Was measured.
- the dye-sensitized solar cell encapsulant composition of the present invention is used as an electrolyte for a dye-sensitized solar cell. It has high resistance to sealing and can be sealed without leakage of electrolyte. As a result, solar cells can be reliably used for a long time without reducing the efficiency of the solar cells.
