- the light-receiving surface protection member 8, the light-receiving surface filler 6, the solar cell connector 10, the back surface filler 7, and the back surface protection member 9 are sequentially laminated in this order, and after lamination, they are heated and integrated. In this way, the solar cell module 1 is formed.
- a frame made of a metal such as aluminum may be disposed at the end of the light receiving surface protection member 8 and the back surface protection member 9.
- the portions of the connecting member 5 that overlap the solar cells 3A and 3B are pressurized simultaneously. Thereby, a pressure can be more reliably applied to the part of the connecting member 5 that overlaps with the solar cells 3A and 3B from the normal direction to the back surfaces of the solar cells 3A and 3B. As a result, the connecting member 5 can be connected to the solar cells 3A and 3B without pressurizing the end portions of the solar cells 3A and 3B, and cracking and chipping can be better prevented.
- the both ends of the connecting member 5 are fixed to the solar cells 3A and 3B at the same time, so that the solar cell 3 can be better prevented from cracking or chipping.
- the electric field may concentrate on a specific place and a protrusion may be formed. In such a case, it is possible to better prevent the solar cell 3 from being cracked or chipped by the protrusions coming into contact with the connecting member 5 and being pressurized.
- the copper foil 16 formed on the polyimide resin film 15 is in contact with the sides of the solar cells 3A and 3B and the protruding portions of the electrodes, and the disconnection caused by pressurization is further reduced. It can be well prevented. Therefore, in the temporary fixing step, it is particularly preferable that the portion overlapping the solar cells 3A and 3B of the connecting member 5 is simultaneously pressed.
- a fixing step of fixing with the adhesive 4 is performed after the temporary fixing step. That is, once the connection member 5 is temporarily fixed at appropriate positions of the solar cell 3 ⁇ / b> A and the solar cell 3 ⁇ / b> B, the thermosetting resin sheet 4 ⁇ / b> A is melted, cured, and fixed as the adhesive 4. As a result, when the thermosetting resin sheet 4A is heated and pressurized, the copper foil of the connecting member 5 disposed on the n-side collector electrode 12b of the solar cell 3A and the p-side collector electrode 11b of the solar cell 3B. 16 positional deviations can be suppressed. As a result, the disconnection which arises when the connection member 5 contacts with another member can be prevented better.
- connection member 5 is connected to the n-side collector electrode 12b of the solar cell 3A and the p-side collector electrode 11b of the solar cell 3B.
- the present invention is not limited to this configuration, and in a solar cell or the like that does not have a collecting electrode, the connection member 5 is connected to the n-side thin wire electrode 12a of the solar cell 3A and the p-side thin wire electrode 11a of the solar cell 3B. You may comprise.
- the connecting member 5 is directly electrically connected to each of the thin wire electrodes 11a and 12a. Therefore, when the FPC is used as the connection member 5, the copper foil 16 is shaped according to the thin wire electrodes 11a and 12a. Specifically, a connecting portion is alternately extended from a straight portion extending in a direction intersecting with the extending direction of the thin wire electrodes 11a and 12a toward the fine wire electrode 11a side and the fine wire electrode 12a side.
- the ACF is used as the adhesive 4 in the connecting step of the connecting member 5 by using a pressurizing / heating device having a shape corresponding to the thin wire electrode 12a of the solar cell 3A and the thin wire electrode 11a of the solar cell 3B. Then, it can be physically bonded while partially conducting. Therefore, in this case, it is not necessary to form the copper foil 16 in accordance with the thin wire electrodes 11a and 12a.
- the copper foil 16 need only be overlapped with the thin wire electrodes 11a and 12a, such as a rectangular shape. Any shape can be used.
- the present invention can be used for manufacturing a solar cell module.
- 1 solar cell module 1 solar cell module, 2 solar cell string, 3, 3A, 3B solar cell, 4 adhesive, 4A thermosetting resin sheet, 4B release paper, 5 connection member, 6 light receiving surface filler, 7 back surface filler, 8 light reception Surface protective member, 9 back surface protective member, 10 solar cell connector, 11 p-side electrode, 11a, 12a fine wire electrode, 11b, 12b collector electrode, 12 n-side electrode, 15 polyimide resin film, 16 copper foil, 20 pressure part 21 Cushion part.

Abstract
Description
太陽電池ストリング2は、複数の太陽電池3が一列に配置され、隣接する太陽電池3同士にまたがるように接続部材5が配置され、電気的に接続されることによって形成される。
以下では、太陽電池ストリング2の接続構造について図2を用い、説明を行う。以下では、説明の便宜の為、隣接する2つの太陽電池3を区別し、一方を太陽電池3Aとし、他方を太陽電池3Bとして説明を行う。隣接する2つの太陽電池3の間では、異なる極性の集電極が対向するように配置される。つまり、太陽電池3Aのn側の集電極12bと、太陽電池3Bのp側の集電極11bが対向するように、太陽電池3A,3Bが配置される。そして、太陽電池3Aのn側電極12と、太陽電池3Bのp側電極11に、接続部材5がまたがるように配置される。より具体的には本実施形態では、太陽電池3Aの集電極12bと、太陽電池3Bの集電極11bに、接続部材5の銅箔16が重畳するように配置される。重畳した接続部材5と太陽電池3A、接続部材5と太陽電池3Bは、接着剤4により物理的に固定され、接続される。
図3は、太陽電池モジュール1の製造方法の手順を示すフローチャートである。始めに複数の太陽電池3を用意する。そして、隣接する太陽電池3A,3Bにおいて、太陽電池3Aのn側の集電極12bと、太陽電池3Bのp側の集電極11bが対向するようにして、所定の間隔を設け、太陽電池3A,3Bを配置する(第1の手段による第1の工程、図3のS1)。
