Problems solved by technology

[0013] The problem to be solved is that, in the conventional technology using bag-shaped sealing members, due to the insufficient sealing structure of the dye-sensitized solar cell components, especially the insufficient sealing structure of the external connection terminals, it cannot be reliably sealed. Prevents the danger of electrolyte leakage from solar cells

Embodiment 1)

[0138] Titanium dioxide paste (trade name Nanoxide D, manufactured by solaronix (ソラロニニクス)) is printed on a porous Ti plate (trade name Tiporous, manufactured by Osaka Titanium Industry Co., Ltd.) with a thickness of 100 μm in the range of 5 mm × 20 mm. Sinter in air at 400°C for 30 minutes. On the sintered titanium dioxide, the operation of printing and sintering the titanium dioxide paste was further repeated six times in total, and a 17 μm thick titanium dioxide layer was formed on one side of the porous Ti plate. At this time, the porous Ti plate was formed with a size of 9 mm×24 mm such that both ends were exposed 2 mm from the titanium dioxide layer of 5 mm×20 mm. The pore diameter distribution of the porous Ti plate was measured by the mercury intrusion method, and the results showed that the pore volume = 0.159cc / g (porosity = 40.1%), and the specific surface area = 5.6m 2 / g, average pore diameter = 8 μm (60% of the pore volume is 4-10 μm).

Embodiment 2)

[0144] Titanium dioxide paste (trade name Nanoxide D, manufactured by Solaronix Co., Ltd.) was printed on a porous Ti plate (trade name Tiporous, manufactured by Osaka Titanium Co., Ltd.) with a thickness of 100 μm in the range of 96 mm × 96 mm, and dried in air at 400 ° C. Sinter for 30 minutes. On the sintered titanium dioxide, the operation of printing and sintering the titanium dioxide paste was further repeated three times in total to form a 10 μm thick titanium dioxide layer on one side of the porous Ti plate. At this time, the porous Ti plate was formed in a size of 98 mm×96 mm such that only one side was exposed by 2 mm from the titanium dioxide layer of 96 mm×96 mm. The pore diameter distribution of the porous Ti plate was measured by the mercury intrusion method, and the results showed that the pore volume = 0.159cc / g (porosity = 40.1%), and the specific surface area = 5.6m 2 / g, average pore diameter = 8 μm (60% of the pore volume is 4-10 μm).

Abstract

Disclosed is a dye-sensitized solar cell, wherein the seal structure of, especially, external connecting terminals, is reliably formed, and a possibility of leaking an electrolytic solution from the solar cell can be eliminated. Also disclosed is a dye-sensitized solar cell module. The dye-sensitized solar cell (10) is provided with: a porous semiconductor layer (12) having a dye adsorbed thereon; a conductive metal layer (14) to be the anode; and a multilayer structure (18) composed of a conductor layer (16) to be the cathode. Extending sections (14a, 16a) are provided by having an end portion of the conductive metal layer (14) and that of the conductor layer (16) extending from the multilayer structure (18). The whole surface of a first resin sheet (22) to be a transparent substrate, and the whole surface of a second resin sheet (24) to be a counter substrate are bonded together and sealed. The extending sections (14a, 16a) are partially exposed from openings (26, 28) provided in the first resin sheet (22) such that the extending sections operate as the external connecting terminals.

Description

technical field [0001] The invention relates to a sealing structure of dye-sensitized solar cell structural components. Background technique [0002] A dye-sensitized solar cell is called a wet solar cell or a Graetzel cell, etc., and is characterized by a cell structure that does not use a silicon semiconductor but has an electrochemical property represented by an iodine solution. Specifically, the dye-sensitized solar cell has a simple structure in which an iodine solution or the like is placed as an electrolytic solution (electrolyte) between a porous semiconductor layer and an opposite electrode made of a conductive glass plate (conductive substrate). , wherein the porous semiconductor layer is a titanium dioxide layer formed by sintering titanium dioxide powder or the like on a transparent conductive glass plate (a transparent conductive substrate on which a transparent conductive film has been laminated), and allowing the titanium dioxide powder to absorb a pigment. ...
