Description
本發明關於一種太陽能電池模組用的集電片，其用以由太陽能電池元件取出電力。 The present invention relates to a current collecting tab for a solar cell module for taking out electric power from a solar cell element.
近年來，由於提高了對於環境問題的意識，作為綠色能源的太陽能電池因而受到注目。一般而言，構成太陽能電池的太陽能電池模組，其構成是由受光面側，依序積層有透明前面基板、表面側密封材料薄片、太陽能電池元件、背面側密封材料薄片及背面保護薄片而成，並且藉由太陽光入射至上述太陽能電池元件而具有發電的機能。 In recent years, solar cells as green energy have attracted attention because of raising awareness of environmental issues. In general, a solar cell module constituting a solar cell is configured by a transparent front substrate, a front side sealing material sheet, a solar cell element, a back side sealing material sheet, and a back surface protective sheet, which are sequentially laminated on the light receiving surface side. And it has a function of generating electricity by being incident on the solar cell element by sunlight.
在太陽能電池模組內部實行發電的太陽能電池元件，通常是以下述方式來構成：在太陽能電池模組的內部設置有複數片太陽能電池元件，並且將這些太陽能電池元件以串聯及/或並聯方式連接，藉此獲得必要的電壓及電流。為了將複數個太陽能電池元件在太陽能電池模組的內部進行配線，例如，已使用了一種太陽能電池模組用的集電片，其是使構成電路之金屬箔積層在基材也就是樹脂薄片的表面上(參照專利文獻1)。 A solar cell element that performs power generation inside a solar cell module is generally configured in such a manner that a plurality of solar cell elements are disposed inside the solar cell module, and the solar cell elements are connected in series and/or in parallel. In order to obtain the necessary voltage and current. In order to wire a plurality of solar cell elements inside the solar cell module, for example, a current collecting tab for a solar cell module in which a metal foil constituting the circuit is laminated on a substrate, that is, a resin sheet, has been used. On the surface (see Patent Document 1).
又，在太陽能電池模組中，從設計性的觀點來看，有時會要求將背面保護薄片的外觀作成暗色。因此，亦開發了一種太陽能電池模組用的背面保護薄片，其在太陽能電池模組用的背面保護薄片中，將包含反射層之複數層的層，隔著黑色黏著劑層來進行積層，藉此具備耐候性和耐久性，並且可對提升太陽能電池模組的發電效率有所貢獻，該黑色黏著劑層是由包含特定的樹脂與暗色系的有機顏料等之黑色黏著劑所構成(專利文獻2)。 Further, in the solar battery module, from the viewpoint of design, the appearance of the back surface protective sheet may be required to be dark. Therefore, a back protective sheet for a solar cell module has been developed in which a layer including a plurality of layers of a reflective layer is laminated with a black adhesive layer in a back protective sheet for a solar cell module. This is weather resistant and durable, and contributes to the improvement of the power generation efficiency of the solar cell module, which is composed of a black adhesive containing a specific resin and a dark color organic pigment (Patent Literature) 2).
專利文獻1：日本特開2007-081237號公報 Patent Document 1: Japanese Laid-Open Patent Publication No. 2007-081237
專利文獻2：日本特開2012-216689號公報 Patent Document 2: Japanese Laid-Open Patent Publication No. 2012-216689
但是，在太陽能電池模組用的集電片中，除了設計性的觀點之外，即便以使連接在太陽能電池元件上的線路圖案無法被目視的意圖來看，亦有要求提高隱蔽性的情況。 However, in the current collecting sheet for a solar battery module, in addition to the design viewpoint, even if the wiring pattern connected to the solar cell element cannot be visually observed, there is a demand for improvement in concealability. .
作為如此的集電片，例如，認為有下述方法：將構成電路之金屬箔與樹脂薄片，隔著黏著劑層進行積層，並利用在該黏著劑層中混入碳黑或暗色系有機顏料等，使連接在太陽能電池元件上的線路圖案無法被目視。 As such a current collecting sheet, for example, a method is known in which a metal foil constituting a circuit and a resin sheet are laminated via an adhesive layer, and carbon black or a dark organic pigment is mixed in the adhesive layer. The line pattern connected to the solar cell element cannot be visually observed.
但是，作為線路，一般所使用的金屬箔的表面，極為容易被氧化。另一方面，已混入顏料之黑色層，會因為顏料本身具有吸溼性而成為吸溼性高的層。因此，與黑色層接近的線路會被氧化，而會有生鏽的問題。 However, as a wiring, the surface of a metal foil generally used is extremely easily oxidized. On the other hand, the black layer which has been mixed with the pigment is a layer having high hygroscopicity because the pigment itself has hygroscopicity. Therefore, the line close to the black layer is oxidized and there is a problem of rust.
當線路生鏽時，線路本身的電阻就會增加。因此，作為太陽能電池模組的發電效率會降低，並且使性能降低。 When the line rusts, the resistance of the line itself increases. Therefore, power generation efficiency as a solar cell module is lowered, and performance is lowered.
因此，為了提高隱蔽性，即便是將黑色層積層時，仍強烈地尋求開發出一種線路不會生鏽的太陽能電池模組用的集電片。 Therefore, in order to improve the concealability, even when a black layer is laminated, it is strongly sought to develop a current collecting sheet for a solar cell module in which the wiring does not rust.
本發明人為了解決上述問題而努力地實行研究的結果著眼於太陽能電池模組用的集電片的層構成，發現了並非介於金屬線路部與樹脂基材之間的黏著劑層，而是將用以防止辨識出金屬線路部之黑色隱蔽層積層在樹脂基材的背面側，藉此，便可一邊具有無法辨識出線路程度之隱蔽性，一邊能夠提升線路的防鏽性。更具體而言，本發明提供以下技術。 The inventors of the present invention have diligently carried out research to solve the above problems, and have focused on the layer structure of the current collecting tab for a solar cell module, and found that the adhesive layer is not interposed between the metal wiring portion and the resin substrate, but The black concealing layer for preventing the identification of the metal wiring portion is formed on the back side of the resin substrate, whereby the rust resistance of the wiring can be improved while having the concealability that the degree of the line cannot be recognized.

〈太陽能電池模組〉 <Solar battery module>
[全體構成] [All composition]
首先，一邊參照第1圖一邊說明本實施形態的太陽能電池模組。本實施形態的太陽能電池模組，是一種薄片狀的積層體，其具有由背面接點型的太陽能電池元件取出電力的機能。並且，本實施形態的太陽能電池模組用的集電片，能夠作為太陽能電池模組的一構成零件來使用。再者，本說明書中所謂的背面接點型的太陽能電池元件，是意指當使用時在設為背面側的面上配置有電極之全部的太陽能電池元件。本實施形態的太陽能電池模組用的集電片，較佳是能夠使用於全部種類的背面接點型的太陽能電池元件。 First, the solar battery module of the present embodiment will be described with reference to Fig. 1 . The solar battery module of the present embodiment is a sheet-like laminated body having a function of taking out electric power from a back contact type solar battery element. Further, the current collecting sheet for a solar battery module of the present embodiment can be used as a component of the solar battery module. In addition, the solar cell element of the back contact type in this specification means the solar cell element in which all the electrodes are arrange|positioned on the surface of the back side at the time of use. The current collecting sheet for a solar battery module of the present embodiment is preferably used in all types of back contact type solar battery elements.
〈太陽能電池模組用的集電片〉 <Collector for solar cell modules>
以下，說明本實施形態的太陽能電池模組用的集電片1。集電片1，如第1圖所示，是一積層體，其依序積層有樹脂基材12、黑色隱蔽層13、背面保護層14，並且金屬線路部10是隔著樹脂基材12與黏著劑層11而被積層。 Hereinafter, the current collecting sheet 1 for a solar battery module of the present embodiment will be described. The current collecting sheet 1, as shown in Fig. 1, is a laminated body in which a resin substrate 12, a black concealing layer 13, and a back surface protective layer 14 are sequentially laminated, and the metal wiring portion 10 is interposed between the resin substrate 12 and The adhesive layer 11 is laminated.
[黑色隱蔽層] [Black hidden layer]
黑色隱蔽層13是用以將金屬線路部10隱蔽成無法從外部辨識的程度之層。黑色隱蔽層13，不與金屬線路部10接近(鄰接)，而是在樹脂基材的背面側，主要是積層在樹脂基材12與背面保護層14之間，藉此，能夠使金屬線路部兼具隱蔽性與防鏽性。 The black concealing layer 13 is a layer for concealing the metal wiring portion 10 to such an extent that it cannot be recognized from the outside. The black concealing layer 13 is not adjacent to (adjacent to) the metal wiring portion 10, but is mainly laminated on the back surface side of the resin substrate between the resin substrate 12 and the back surface protective layer 14, whereby the metal wiring portion can be formed. Both concealed and rust-proof.
黑色隱蔽層13，可以積層在樹脂基材的背面側，例如可以利用以下的方法進行積層：如第1圖所示，使用含有黑色顏料之黑色黏著劑作為黏著劑層來進行積層；在樹脂基材上塗佈含有黑色顏料之墨水，藉此形成黑色隱蔽層，進一步隔著黏著劑層使樹脂基材與背面保護層進行積層(並未圖示)；將配置在集電片在最外層的背面保護層設為兩層，在兩層之間設置黏著劑層或墨水層，並且也可將其作為黑色隱蔽層來進行積層(並未圖示)。 The black concealing layer 13 may be laminated on the back side of the resin substrate, and for example, it may be laminated by the following method: as shown in Fig. 1, a black adhesive containing a black pigment is used as an adhesive layer to laminate; The black pigment is coated on the material to form a black concealing layer, and the resin substrate and the back surface protective layer are further laminated via an adhesive layer (not shown); and the current collecting sheet is disposed at the outermost layer. The back protective layer is provided in two layers, and an adhesive layer or an ink layer is provided between the two layers, and it may be laminated as a black concealing layer (not shown).
其中，只要是如第1圖所示，使用含有黑色顏料之黑色黏著劑，以作為介於樹脂基材與背面保護層之間的黏著劑層的方式來進行積層，即便為了設置黑色隱蔽層而未設置新的積層步驟，亦能夠製造出作為本發明目的之具有防鏽性及隱蔽性的集電片。因此，從集電片的生產性的觀點來看，特別較佳的是：使用黑色黏著劑來作為介於 樹脂基材與背面保護層之間的黏著劑層，來將黑色隱蔽層進行積層。 In addition, as shown in FIG. 1, a black adhesive containing a black pigment is used to laminate the adhesive layer between the resin substrate and the back surface protective layer, even if a black concealing layer is provided. It is also possible to manufacture a current collecting sheet having rust preventing property and concealing property as the object of the present invention without providing a new lamination step. Therefore, from the viewpoint of productivity of the current collector sheet, it is particularly preferable to use a black adhesive as an inter An adhesive layer between the resin substrate and the back protective layer to laminate the black concealing layer.
黑色隱蔽層13中所含有的黑色顏料，能夠使用先前公知的顏料。例如可以使用：如碳黑的無機顏料或噁(oxazine)系、苯并咪唑酮系、吡咯系、喹吖酮系、偶氮系、迫聯萘系、二氧雜環系、異吲哚啉酮系、陰丹士林系、喹啉黃系、迫位酮(perynone)系、酞青素系等暗色系的有機顏料，亦可以使用將這些顏料兩種以上混合而成的顏料。藉由使用暗色系的有機顏料，能夠抑制黑色隱蔽層13所吸收的紅外線的吸收量。因此，能夠抑制太陽能電池模組用的集電片的發熱。 The black pigment contained in the black concealing layer 13 can use a conventionally known pigment. For example, you can use: inorganic pigments such as carbon black or evil (oxazine), benzimidazolone, pyrrole, quinophthalone, azo, thionaphthalene, dioxane, isoindolinone, indanthrene, quinoline yellow A dark color organic pigment such as a perynone system or an anthraquinone system may be used, and a pigment obtained by mixing two or more of these pigments may also be used. By using a dark-colored organic pigment, the amount of absorption of infrared rays absorbed by the black concealing layer 13 can be suppressed. Therefore, heat generation of the current collecting tab for the solar cell module can be suppressed.
從耐UV黏著性的觀點來看，較佳是能夠使用噁系的有機顏料。又，當藉由添加暗色系的有機顏料，將黑色隱蔽層作為黏著劑層來進行積層時，可提升黑色隱蔽層的熱耐久性或耐UV特性等黏著耐久性。從提升此黏著耐久性的觀點來看，特別較佳是能夠使用噁系的有機顏料。 From the standpoint of UV adhesion resistance, it is better to use evil Department of organic pigments. Moreover, when a black concealing layer is laminated as an adhesive layer by adding a dark-colored organic pigment, adhesion durability such as thermal durability and UV resistance of the black concealing layer can be improved. From the standpoint of improving the adhesion durability, it is particularly preferable to be able to use evil Department of organic pigments.
作為噁系的有機顏料，例如能夠適合使用如日本特開2003-105217號公報所述之二噁系化合物等，而無特別的限定。較佳的含量是以固形分質量比計10%以上且30%以下的程度。 As evil The organic pigment of the system can be suitably used, for example, as described in Japanese Laid-Open Patent Publication No. 2003-105217. A compound or the like is not particularly limited. The content is preferably 10% or more and 30% or less by mass% of the solid content.
又，作為暗色系的有機顏料，特別較佳是包含選自由苯并咪唑酮系顏料、4-[(2,5-二氯苯基)偶氮]-3-羥基-N-(2,5-二甲氧苯基)-2-萘羧醯胺、1-[(4-硝苯 基)偶氮]-2-萘酚、雙[3-羥基-4(苯偶氮)-2-萘羧酸]銅鹽、N,N’-雙(2,4-二硝苯基)-3,3’-二甲氧基-1,1’-聯苯基-4,4’-二胺、3,4,9,10-迫聯萘四羧酸二醯亞胺、△2,2’(1H,1’H)-聯萘并[2,1-b]噻吩-1,1’-二酮、及N,N’-(10,15,16,17-四氫-5,10,15,17-四氧-5H-二萘并[2,3-a：2’,3’-i]咔唑-4,9-二基)雙(苯甲醯胺)所組成之群組中的至少一種以上的棕色系顏料與酞青素系顏料而成的顏料。藉由使用棕色系顏料與酞青素系顏料，即便黑色隱蔽層13的厚度較薄時，仍能夠成為具有充分隱蔽性的黑色隱蔽層13。因此，從生產性的觀點來看，較佳是使用包含棕色系顏料與酞青素系顏料所組成之顏料。進一步，當在胺酯系、碳酸酯系、或環氧系的黏著劑層中，含有棕色系顏料及酞青素系顏料時，能夠與含有噁系顏料之黑色隱蔽層具有相同的黏著性。再者，棕色系顏料，從黑色隱蔽層中的顏料的分散性或黏著層的黏著性等觀點來看，較佳是苯并咪唑酮系顏料。 Further, as the dark color organic pigment, it is particularly preferred to contain a pigment selected from the group consisting of benzimidazolone-based pigments, 4-[(2,5-dichlorophenyl)azo]-3-hydroxy-N-(2,5) -dimethoxyphenyl)-2-naphthylcarboxamide, 1-[(4-nitrophenyl)azo]-2-naphthol, bis[3-hydroxy-4(phenylazo)-2-naphthalene Carboxylic acid] copper salt, N,N'-bis(2,4-dinitrophenyl)-3,3'-dimethoxy-1,1'-biphenyl-4,4'-diamine, 3,4,9,10-forced naphthalenetetracarboxylic acid diimine, Δ2,2'(1H,1'H)-binaphtho[2,1-b]thiophene-1,1'-di Ketone, and N,N'-(10,15,16,17-tetrahydro-5,10,15,17-tetraoxa-5H-dinaphtho[2,3-a:2',3'-i a pigment obtained by mixing at least one of a brown pigment and an anthraquinone pigment in a group consisting of carbazole-4,9-diyl)bis(benzamide). By using the brown pigment and the anthraquinone pigment, even when the thickness of the black concealing layer 13 is thin, the black concealing layer 13 having sufficient concealability can be obtained. Therefore, from the viewpoint of productivity, it is preferred to use a pigment comprising a brown pigment and an anthraquinone pigment. Further, when an amine ester-based, carbonate-based, or epoxy-based adhesive layer contains a brown pigment and an anthraquinone pigment, it can contain evil The black concealment layer of the pigment has the same adhesion. Further, the brown pigment is preferably a benzimidazolone pigment from the viewpoints of dispersibility of the pigment in the black concealing layer or adhesion of the adhesive layer.

將以下種類的樹脂薄片，藉由下述表1所示的組合，利用黏著劑1及黏著劑2進行黏著，來作成實施例及比較例的集電片樣品。試料作成是藉由下述方法來製成：將黏著劑1或2，在基材樹脂(聚苯二甲酸乙二酯(厚度188μm))上進行凹版塗佈(塗佈量8g/m2)，並且形成厚度8μm(乾燥狀態)的黏著劑層，然後藉由乾式疊層來積層導電性基材(銅箔，25μm)及背面保護層(耐水解性PET(白，50μm))而成為積層體，該積層體是以成為導電性基材/黏著劑層/樹脂基材/黏著劑層/背面保護層的方式積層而成。 The following types of resin sheets were adhered by the adhesive 1 and the adhesive 2 by the combination shown in the following Table 1, and the current collector sheets of the examples and the comparative examples were prepared. The sample preparation was carried out by gravure coating (coating amount 8 g/m 2 ) on the base resin (polyethylene terephthalate (thickness 188 μm)) with the adhesive 1 or 2 And an adhesive layer having a thickness of 8 μm (dry state) was formed, and then a conductive substrate (copper foil, 25 μm) and a back protective layer (hydrolyzable PET (white, 50 μm)) were laminated by dry lamination to form a laminate. The laminate is formed by laminating the conductive substrate/adhesive layer/resin base material/adhesive layer/back surface protective layer.
實施例的積層體，其是將導電性基材隔著黏著劑層而積層在樹脂基材上，並且將背面保護層隔著黑色隱蔽層(黏著劑層)積層在樹脂基材上；該黏著劑層是藉由黏著劑2所形成，該黑色隱蔽層是藉由黏著劑1所形成。比較例的積層體，其是將導電性基材隔著黑色隱蔽層(黏著劑層)積層在樹脂基材上，並且將背面保護層隔著黏著劑層積層在樹脂基材上；該黑色隱蔽層是藉由黏著劑1所形成，該黏著劑層是藉由黏著劑2所形成。 In the laminate of the embodiment, the conductive substrate is laminated on the resin substrate via the adhesive layer, and the back protective layer is laminated on the resin substrate via the black concealing layer (adhesive layer); The agent layer is formed by an adhesive 2 which is formed by the adhesive 1. In the laminate of the comparative example, the conductive substrate is laminated on the resin substrate via a black concealing layer (adhesive layer), and the back protective layer is laminated on the resin substrate via an adhesive; the black concealment The layer is formed by an adhesive 1 which is formed by an adhesive 2.
進一步，在這些積層體的表面使用乾膜(dry film)，然後製作成一種厚度15μm、寬度150mm、長度150mm的蝕刻罩。之後，將溫度45℃、濃度250g/L的氯化鐵水溶液設為蝕刻液，將上述已形成有上述蝕刻遮罩之積層體浸漬於此蝕刻液中約2分鐘，接下來，利用純水進行洗淨。藉此，去除並未被蝕刻遮罩所覆蓋之處的導電性基材，來獲得實施例及比較例中的集電片。 Further, a dry film was used on the surface of these laminates, and then an etching cover having a thickness of 15 μm, a width of 150 mm, and a length of 150 mm was produced. Thereafter, an aqueous solution of ferric chloride having a temperature of 45° C. and a concentration of 250 g/L was used as an etching liquid, and the laminate in which the etching mask was formed was immersed in the etching liquid for about 2 minutes, and then, it was carried out with pure water. Wash. Thereby, the conductive substrate which was not covered by the etching mask was removed, and the current collecting sheets in the examples and the comparative examples were obtained.
[防鏽性試驗] [rust resistance test]
對實施例及比較例的各試料，進行防鏽性試驗。試驗是藉由將各試料放置在85℃、85%RH中24小時後來實行，防鏽性的評價，藉由目視來實行，並且依照以下的基準。將防鏽性試驗結果作為「防鏽性」表示在表1。 The rust resistance test was performed on each sample of the examples and the comparative examples. The test was carried out by placing each sample at 85 ° C and 85% RH for 24 hours, and the evaluation of the rust preventive property was carried out by visual observation and in accordance with the following criteria. The results of the rust preventive test are shown in Table 1 as "rust resistance".
○：雖然線路圖案的背面的金屬光澤有稍微變低但並未呈現變色 ○: Although the metallic luster on the back side of the line pattern is slightly lowered, it does not exhibit discoloration.
×：線路圖案有部分地變色 ×: The line pattern is partially discolored
藉由表1可知：只將黑色隱蔽層積層在樹脂基材的背面側之實施例而製成的本發明的集電片，是防鏽性優異的集電片。 As can be seen from Table 1, the current collecting sheet of the present invention produced by the embodiment in which only the black concealing layer is laminated on the back side of the resin substrate is a current collecting sheet excellent in rust preventive property.
實施例及比較例中的集電片樣品，當從背面保護層側以目視確認金屬線路部時，實施例及比較例的集電片樣品皆無法確認金屬線路部。由此可知，本發明的集電 片，與隔著黑色隱蔽層將樹脂基材和金屬線路部積層而成的集電片，同樣地是具有無法目視線路圖案程度之隱蔽性的集電片。 In the current collector sheet samples of the examples and the comparative examples, when the metal wiring portions were visually confirmed from the back surface protective layer side, the metal wiring portions could not be confirmed in the current collector sheet samples of the examples and the comparative examples. It can be seen that the current collection of the present invention In the same manner, the current collecting sheet in which the resin base material and the metal wiring portion are laminated with the black hidden layer is similar to the current collecting sheet having a degree of visibility which is incapable of visually observing the line pattern.
