no. 1 approach

[0075] Such as figure 1 as well as figure 2 As shown, the solar cell module 1 of the first embodiment of the present invention is prepared by the following roll-to-roll method (hereinafter referred to as the R to R method), which is a thin-film type elongated in the first direction (length direction X1). The dye-sensitized solar cell is manufactured by cutting it to a specific length. The solar cell module 1 has a battery structure in which two blocks (submodules R, R) composed of a plurality of cells C arranged in a width direction X2 (second direction) orthogonal to the longitudinal direction X1 when viewed from above are adjacent in the longitudinal direction X1 , The adjacent sub-modules R and R are electrically connected at one end 1a side of the width direction X2.

[0076] in figure 1 and figure 2 In the figure, the arrow indicates the flow of current, and the symbols + (positive) and-(negative) indicate the positive electrode and the negative electrode, respectively (...

no. 2 approach

[0131] Such as Image 6 As shown, the dye-sensitized solar cell 101 (solar cell module) of the second embodiment is prepared in the first direction (length direction X1) according to the following roll-to-roll method (hereinafter referred to as R to R method) The long-stretched thin-film dye-sensitized solar cell is manufactured by cutting it to a specific length.

[0132] in Image 6 In the middle, the arrow indicates the direction of current flow ( Figure 7 The same is true), and the symbols + (positive) and-(negative) respectively indicate the positive electrode and the negative electrode (the same applies to other figures).

[0133] Here, in the dye-sensitized solar cell 101, as described above, the longitudinal direction X1 is set as the arrangement direction of the submodules R, and the width direction X2 is set as a direction orthogonal to the longitudinal direction X1 in a plan view, and these are collectively used below.

[0134] Such as Figure 7 As shown, the dye-sensitiz...

no. 3 Embodiment approach

[0182] Figure 20 The dye-sensitized solar cell 101A of the second embodiment shown is a battery structure in which two blocks (submodules R, R) composed of a plurality of cells C arranged in the width direction X2 are adjacent to each other in the length direction X1. The adjacent submodules R and R are electrically connected to each other on the side of one end 101a in the width direction X2.

[0183] The ultrasonic fusion part 118 extends from the other end 1b to the one end 101a side in a state where the wiring material 119 on the one end 101a side is left in the width direction X2 of each submodule R, R. Thereby, a circuit in which the photoelectrode 111 and the counter electrode 112 of each of the submodules R and R are electrically connected through the wiring material 119 is formed.

[0184] In the third embodiment, the sub-modules R and R on the one end 1a side of the longitudinal direction X1 are electrically connected to each other by the wiring material 119, and the end...

Abstract

The purpose of this invention is to provide a solar cell module and a method for producing solar cell, with which wiring can be performed efficiently by adopting a structure in which electrodes can be positioned leading out from the edge on the same side. This invention pertains to a solar cell module having a structure wherein a plurality of cells arranged in the width direction (X2) are electrically connected to one another by wires, a conductor (14) is positioned between a first insulating member of a first substrate (3A) and a second insulating part of a second substrate (3B) positioned between cells which adjoin one another in the width direction (X2), adjoining cells are connected to one another, and conductors (14) on one end (1a) side in the width direction (X2) in the pair of adjoining sub-modules (R, R) divided in the longitudinal direction (X1) by an insulating part (18) are electrically connected to one another, forming a circuit structure.

Description

Technical field [0001] The invention relates to a solar cell module and a manufacturing method of the solar cell module. [0002] This application claims priority based on Japanese Patent Application No. 2017-059239 filed in Japan on March 24, 2017 and Japanese Patent Application No. 2017-068340 filed in Japan on March 30, 2017, and uses the content here. Background technique [0003] It is known that a solar cell module composed of a dye-sensitized solar cell generally includes a photoelectrode, a counter electrode, an electrolyte or an electrolyte layer, and at least a transparent conductive layer, a semiconductor layer, and a dye as the photoelectrode (for example, refer to Patent Document 1) . In such a solar cell module, for example, when light is irradiated to the photoelectrode side, the dye adsorbed on the semiconductor layer absorbs the light, electrons in the dye molecules are excited, and the electrons are transferred to the semiconductor. Then, the electrons generated...
