Description
Technical field
The present invention relates to solar cell module and the manufacturing methods of solar cell module.
The application is based on November 7th, 2016 in the Japanese Patent 2016-217426 filed an application, March 24 in 2017
The Patent 2017-059716 CLAIM OF PRIORITY that day files an application in Japan, is hereby incorporated its content.
Background technique
Currently, dye-sensitized solar cells is generally configured with optoelectronic pole, opposite electrode, electrolyte or electrolyte layer and structure
At.As optoelectronic pole, it is known at least have transparency conducting layer, semiconductor layer, dyestuff and constitute.In this dye sensitization sun
In energy battery, for example, the dyestuff for being adsorbed in semiconductor layer absorbs light, the electronics in dye molecule when to optoelectronic pole irradiation light
It is motivated, which shifts to semiconductor.Moreover, the electronics generated from optoelectronic pole is mobile to opposite electrode by external circuit,
The electronics returns to optoelectronic pole by electrolyte.By repeating this process, produce electricl energy.
As the manufacturing method for the solar cell module being made of this dye-sensitized solar cells, such as such as patent
Shown in document 1, it is known to the first electrode being bonded in a manner of roll-to-roll and second electrode be insulated by using ultrasonic activation
And deposition and the method that is divided into multiple units.
Patent document 1:(Japan) No. 5702897 bulletin of special permission
But in the existing solar cell module being made of dye-sensitized solar cells, there are following to ask
Topic.
That is, in the solar cell module disclosed in patent document 1, in order to connect unit in series and parallel, roller will be being passed through
After being cut off in a manner of separating to the longitudinal direction for the electrode that roller mode continuously manufactures, in order to by these divided solar-electricities
Pond module is serially connected and carries out wiring operation.Therefore, it is necessary to the addition processes with wiring, and there are manufacturing cost increases
The problem of.That is, in the case where being configured at multiple solar cell modules such as shutter, by multiple solar batteries
After module is attached on the substrate of shutter with state spaced at intervals, each solar cell module is one another in series company
It connects, may will increase for the time of wiring or cost.
Summary of the invention
The present invention is to create in view of the above problems, and its purpose is to provide one kind by the way that be formed as only can be in film
The construction that series wiring is carried out on substrate, can carry out the production based on roll-to-roll mode, and do not need in exterior solar-electricity
The wiring generated when the module of pond can be realized the manufacture of the reduced solar cell module and solar cell module of cost
Method.
In order to solve the above-mentioned technical problem, related purpose is realized, the present invention is by the way of following.
(1) solar cell module of one aspect of the present invention, be comprising first electrode, second electrode, be sealed in it is described
Electrolyte between first electrode and the second electrode, multiple sealing materials of the sealing electrolyte, multiple insulated wires
Layered structure, the solar cell module have being limited by the multiple sealing material and the multiple insulated wire and divide
The multiple submodule not being made of multiple units, wherein the first electrode, which has, is formed with the of transparent conductive film on surface
One substrate and be formed in the first base material the transparent conductive film surface, the absorption that extends in a first direction dye
Multiple strip-shaped semiconductor layers of material, the second electrode, which has, to be formed with pair on surface in the mode opposed with the first electrode
Set the second substrate of conductive film, the electrolyte be sealed in the first electrode the semiconductor layer and the second electrode
Between, the multiple sealing material prolongs between the first electrode and the second electrode along the first direction respectively
It stretches, thus seals the electrolyte, while the layered structure is divided into multiple units, the multiple insulated wire difference
Extend between the first electrode and the second electrode along second direction orthogonal with the first direction when overlooking, by
The layered structure, is divided into the multiple submodule being made of multiple units, about in this second direction by this respectively
The second electrode of adjacent unit, the first electrode of a unit and another unit passes through the state to be covered by the sealing material
The conductive material of setting is electrically connected, and thus the multiple unit is connected in series, in each unit, to prevent first electrode and the
The mode of two electric pole short circuits is equipped near the position adjacent with a conductive material along described first in the first base material
