Abstract
Description
本発明は、バックコンタクト型太陽電池モジュールの配線シートに関する。 The present invention relates to a wiring sheet for a back contact solar cell module.
近年、地球温暖化問題に対する内外各方面の関心が高まる中、二酸化炭素の排出抑制のために、様々な努力が続けられている。化石燃料の消費量の増大は大気中の二酸化炭素の増加をもたらし、その温室効果により地球の気温が上昇し、地球環境に重大な影響を及ぼす。この地球規模の問題を解決するために様々な検討が行われており、特に太陽光発電については、そのクリーン性や無公害性という点から期待が高まっている。 In recent years, various efforts have been made to suppress carbon dioxide emissions while interest from various countries both inside and outside Japan has increased. Increasing fossil fuel consumption leads to an increase in atmospheric carbon dioxide, and the greenhouse effect raises the Earth's temperature, significantly affecting the global environment. Various studies have been carried out to solve this global problem, and in particular, solar power generation is highly expected in terms of cleanliness and non-pollution.
太陽電池は、太陽光のエネルギーを直接電気に換える太陽光発電システムの心臓部を構成するものであり、単結晶、多結晶、又はアモルファスシリコン系の半導体からできている。太陽電池素子は、その単体での電気出力が小さい為に、太陽電池素子（セル）単体をそのままの状態で使用することはなく、一般的には、各太陽電池セルに接続されたインターコネクタ同士を接続することにより、数枚〜数十枚の太陽電池セルを直列、並列に配線し、長期間（約２０年）に亘ってセルを保護するために種々パッケージングが行われ、ユニット化されている。このパッケージに組み込まれたユニットを「太陽電池モジュール」と呼んでいる。 A solar cell constitutes the heart of a photovoltaic power generation system that directly converts sunlight energy into electricity, and is made of a single crystal, polycrystalline, or amorphous silicon semiconductor. Since the solar cell element has a small electrical output, the solar cell element (cell) is not used as it is. In general, interconnectors connected to each solar cell are connected to each other. By connecting, several to dozens of solar cells are wired in series and in parallel, and various packaging is performed to protect the cells over a long period (about 20 years). ing. The unit incorporated in this package is called a “solar cell module”.
現在も最も多く生産されている太陽電池は、太陽光を受ける受光面がｎ電極で、その裏面がｐ電極から構成されている。受光面側に設けられるｎ電極は電流の取り出しの為には必要不可欠であるが、一方で、その電極の下の基板には太陽光が入射しないため、その部分では発電しない問題がある。従って、変換効率を上げるためには、この受光面側の電極面積を限りなく小さくすることが重要であり、その一つの方法として、ｎ電極およびｐ電極の両電極を裏面に形成したバックコンタクト型太陽電池モジュールが提案されている。 The solar cells that are produced most frequently today have an n-electrode on the light-receiving surface that receives sunlight, and a p-electrode on the back surface. The n-electrode provided on the light-receiving surface side is indispensable for taking out current, but on the other hand, since sunlight does not enter the substrate under the electrode, there is a problem that power is not generated in that portion. Therefore, in order to increase the conversion efficiency, it is important to reduce the electrode area on the light receiving surface side as much as possible. As one of the methods, a back contact type in which both an n electrode and a p electrode are formed on the back surface. Solar cell modules have been proposed.
上記バックコンタクト型太陽電池モジュールの太陽電池セルの接続方法として、例えばインターコネクタでの接続方法が提案されている（特許文献１参照）。しかしながら、インターコネクタでの接続方法では、半田付けによる熱の影響で太陽電池セルに反りが生じ接続精度に問題がある。また、複数の太陽電池セルの配置部を有する配線シートに、バックコンタクト型太陽電池セルを載置して、配線シートにより各太陽電池セル間を電気的に接続する方法も提案されている（特許文献２参照）。この提案の配線シートは、金属箔と絶縁性を有するフレキシブルな基材（プラスチックフィルム基材）の積層体からなり、該金属箔に各太陽電池セル間を接続するための回路パターンが形成されている。 As a method for connecting solar cells of the back contact solar cell module, for example, a connection method using an interconnector has been proposed (see Patent Document 1). However, the connection method using the interconnector has a problem in connection accuracy due to warpage of the solar battery cells due to the influence of heat due to soldering. In addition, a method has been proposed in which back contact solar cells are placed on a wiring sheet having a plurality of solar cell arrangement portions, and the solar cells are electrically connected by the wiring sheet (patent). Reference 2). The proposed wiring sheet is composed of a laminate of a metal foil and a flexible base material (plastic film base material) having an insulating property, and a circuit pattern for connecting the solar cells is formed on the metal foil. Yes.
しかしながら、上記配線シートと太陽電池セルを熱ラミネートによりモジュール化する際に、前記フレキシブルな基材（プラスチックフィルム基材）と金属箔はいずれも熱収縮するが、前記フレキシブルな基材（プラスチックフィルム基材）は金属箔に比べて極めて大きな熱収縮をおこす。そのために、金属箔側にシワが発生する。また、特に回路パターンがけ形成されていない部分、すなわちプラスチックフィルム基材の面積に比べて金属箔の面積比率が小さい部分では、応力が集中してシワが発生し易く、また配線シート全体にカールが発生し易く問題である。 However, when the wiring sheet and solar cells are modularized by thermal lamination, both the flexible base material (plastic film base material) and the metal foil are thermally shrunk, but the flexible base material (plastic film base material) The material) causes extremely large heat shrinkage compared to the metal foil. Therefore, wrinkles are generated on the metal foil side. In particular, in a portion where the circuit pattern is not formed, that is, a portion where the area ratio of the metal foil is small compared to the area of the plastic film substrate, stress is concentrated and wrinkles are easily generated, and the entire wiring sheet is curled. It is a problem that easily occurs.
太陽電池セルは急速に薄膜化が進んでおり、従来にも増して各太陽電池セル間を正確に接続できる生産性と高い信頼性が要求されている。本発明は上記問題に鑑みてなされたものであり、バックコンタクト方式の太陽電池モジュールを生産する際に、シワやカールが発生しない太陽電池用配線シートの提供を目的とする。 Solar cells are rapidly becoming thinner, and higher productivity and higher reliability are required to connect solar cells more accurately than ever before. The present invention has been made in view of the above problems, and an object of the present invention is to provide a solar cell wiring sheet that does not generate wrinkles or curls when a back contact solar cell module is produced.
本発明は、上記課題を解決することを目的としたものであり、本発明の請求項１に係る発明は、表面に回路パターンが形成された絶縁性基材の裏面に、接着剤層を介して、アルミニウム層、耐候性基材を順次積層してなることを特徴とする太陽電池用配線シートである。 The present invention aims to solve the above problems, and the invention according to claim 1 of the present invention provides an adhesive layer on the back surface of an insulating substrate having a circuit pattern formed on the surface. A solar cell wiring sheet comprising an aluminum layer and a weather-resistant substrate which are sequentially laminated.
本発明の請求項２に係る発明は、前記アルミニウム層の厚みが、６μｍ〜７０μｍであることを特徴とする請求項１に記載の太陽電池用配線シートである。 Invention of Claim 2 of this invention is the wiring sheet for solar cells of Claim 1 whose thickness of the said aluminum layer is 6 micrometers-70 micrometers.
本発明の配線シートを用いることで、シワやカールがなく、各太陽電池セル間を正確に接続することでき、高い生産性と信頼性を保持したバッコンタクト型太陽電池を製造することができる。 By using the wiring sheet of the present invention, there is no wrinkle or curl, and each solar cell can be accurately connected, and a back contact type solar cell having high productivity and reliability can be manufactured.
以下、本発明の太陽電池用配線シートについて、図面を参照して詳細に説明する。 Hereinafter, the wiring sheet for solar cells of the present invention will be described in detail with reference to the drawings.
図１は本発明の太陽電池用配線シートの模式的断面図、図２は従来の太陽電池用配線シートの模式的構成断面図を示す。 FIG. 1 is a schematic sectional view of a solar cell wiring sheet of the present invention, and FIG. 2 is a schematic sectional view of a conventional solar cell wiring sheet.
従来の太陽電池用配線シートは図２に示すように、絶縁性基材２と回路パターン１の積層体からなり、そのために、プラスチックフィルム基材からなる絶縁性基材２と金属箔からなる回路パターン１の、それぞれの熱収縮率の著しい違いにより、太陽電池モジュールの作製工程である熱ラミネーションにおいて、太陽電池用配線シートにシワやカールが発生して各セル間での正確な接続が出来難い問題があった。 As shown in FIG. 2, a conventional solar cell wiring sheet is composed of a laminate of an insulating substrate 2 and a circuit pattern 1, and for this purpose, a circuit comprising an insulating substrate 2 made of a plastic film substrate and a metal foil. Due to the significant difference in the thermal contraction rate of each pattern 1, wrinkles and curls are generated in the solar cell wiring sheet in the thermal lamination process, which is a manufacturing process of the solar cell module, and it is difficult to accurately connect the cells. There was a problem.
本発明は、図１に示すように、表面に回路パターン１が形成された絶縁性基材２の裏面に、接着剤層を介して、アルミニウム層３、耐候性基材４を順次積層した積層体からなる太陽電池用配線シートである。本発明は前記アルミニウム層３の剛性を活かし、太陽電池用配線シートの中間層として構成することで、シワやカールの発生を防ぐ作用効果を得ることができる。 As shown in FIG. 1, the present invention is a laminate in which an aluminum layer 3 and a weather-resistant substrate 4 are sequentially laminated on the back surface of an insulating substrate 2 having a circuit pattern 1 formed on the front surface via an adhesive layer. It is a wiring sheet for solar cells made of a body. The present invention can obtain the effect of preventing the generation of wrinkles and curls by making use of the rigidity of the aluminum layer 3 and constituting it as an intermediate layer of a wiring sheet for solar cells.
＜回路パターン＞
本発明に係る回路パターン１の形成に用いられる金属層は、回路パターンの形成のし易さから銅、アルミニウムが望ましい。また、回路パターン形成はフォトエッチング法や金属ペーストからなるインクを用いたスクリーン印刷法などが適用できる。また、前記金属層の厚みは、１０μｍ〜１００μｍが好ましい。１０μｍ未満であると、過電流や温度変化による影響で断線が生じる可能性があり、１００μｍを超えるとコスト的に望ましくな
い。
<Circuit pattern>
The metal layer used for forming the circuit pattern 1 according to the present invention is preferably copper or aluminum because of the ease of forming the circuit pattern. The circuit pattern can be formed by a photo etching method or a screen printing method using an ink made of a metal paste. The thickness of the metal layer is preferably 10 μm to 100 μm. If it is less than 10 μm, disconnection may occur due to the influence of overcurrent or temperature change, and if it exceeds 100 μm, it is not desirable in terms of cost.
＜絶縁性基材＞
本発明に係る絶縁性基材２としては、太陽電池モジュール化の一般的な加工条件、特に加工温度で変形しない優れた耐熱性を有することが重要であり、融点が１５０℃以上の高分子延伸フィルムまたは該高分子延伸フィルムの複合体を使用することができる。好ましくはポリエチレンテレフタレート（ＰＥＴ）、ポリエチレンナフタレート（ＰＥＮ）、ポリイミド（ＰＩ）、ポリアミド（ＰＡ）などである。また、これらの高分子延伸フィルムに耐候性、水蒸気や酸素ガスバリア性、あるいは易接着性を付加した層を設けた複合体であってもよい。前記絶縁性基材の融点が１５０℃未満であると寸法安定性に欠け、太陽電池セルの配置部と回路シートとの接続位置合わせの精度が低下し、太陽電池モジュールに求められる性能が発揮できない。また、前記絶縁性基材の厚みは、６μｍ〜４００μｍが好ましい。厚みが６μｍ未満であると絶縁性が不足し、４００μｍを超えると熱収縮が大きくなり、太陽電池用配線シートの変形をアルミニウム層の作用効果で防ぐことが難しく、また、コストの問題が生じる。
<Insulating base material>
As the insulating base material 2 according to the present invention, it is important to have an excellent heat resistance that is not deformed at a general processing condition for solar cell modularization, particularly at a processing temperature, and a polymer stretch having a melting point of 150 ° C. or higher. A film or a composite of the polymer stretched film can be used. Polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyimide (PI), polyamide (PA) and the like are preferable. Moreover, the composite_body | complex which provided the layer which added weather resistance, water vapor | steam and oxygen gas barrier property, or easy-adhesiveness to these polymer stretched films may be sufficient. If the melting point of the insulating base material is less than 150 ° C., the dimensional stability is lacking, the accuracy of connection alignment between the solar cell arrangement part and the circuit sheet is lowered, and the performance required for the solar cell module cannot be exhibited. . Moreover, the thickness of the insulating substrate is preferably 6 μm to 400 μm. If the thickness is less than 6 μm, the insulation is insufficient, and if it exceeds 400 μm, thermal shrinkage increases, and it is difficult to prevent the deformation of the solar cell wiring sheet by the effect of the aluminum layer, and there is a problem of cost.
＜アルミニウム層＞
本発明に係るアルミニウム層３は、その剛性により、太陽電池モジュール作製工程の熱ラミネート工程において発生するシワやカールを防ぐことに加えて、バリア性による信頼性向上の作用効果をもたらすことができる。前記アルミニウム層３の厚さは、６μｍ〜７０μｍが好ましく、６μｍ未満であると剛性が不足して太陽電池用配線シートの変形を防ぐことができない。また、７０μｍを超えるとコストや重量の問題が生じる。
<Aluminum layer>
Due to its rigidity, the aluminum layer 3 according to the present invention can bring about the effect of improving the reliability due to the barrier property in addition to preventing wrinkles and curls that occur in the thermal lamination process of the solar cell module manufacturing process. The thickness of the aluminum layer 3 is preferably 6 μm to 70 μm, and if it is less than 6 μm, the rigidity is insufficient and deformation of the solar cell wiring sheet cannot be prevented. Moreover, when it exceeds 70 micrometers, the problem of cost or a weight will arise.
＜耐候性基材＞
本発明に係る耐候性基材４としては、長期間、太陽光や風雨に暴露されても著しい劣化が生じない耐候性を有するプラスチックフィルムが好ましく、要求される耐候性の程度によっては前記絶縁性基材を用いることもできるが、特にパーフルオロアルコキシ樹脂（ＰＦＡ）、４フッ化エチレン−６フッ化プロピレン共重合体（ＦＥＰ）、エチレン−４フッ化エチレン共重合体（ＥＴＦＥ）、塩化−３フッ化エチレン樹脂（ＰＣＴＦＥ）、ポリフッ化ビニリデン（ＰＶＤＦ）、ポリフッ化ビニル（ＰＶＦ）等のフッ素樹脂や低オリゴマーＰＥＴをフィルム化したもの等が好ましい。前記耐候性基材４の厚みは、６μｍ〜１００μｍが好ましく、６μｍ未満であると強度と耐候性が不足し、１００μｍを超えると熱収縮が大きくなり、太陽電池用配線シートの変形をアルミニウム層の作用効果で防ぐことが難しく、また、コストの問題が生じる。
<Weather-resistant substrate>
As the weather resistant substrate 4 according to the present invention, a plastic film having a weather resistance that does not significantly deteriorate even when exposed to sunlight or wind and rain for a long period of time is preferable. Although a base material can also be used, in particular, perfluoroalkoxy resin (PFA), tetrafluoroethylene-6 fluoropropylene copolymer (FEP), ethylene-4 fluoroethylene copolymer (ETFE), chloride-3 A fluororesin such as ethylene fluoride resin (PCTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), or a material obtained by forming a film of low oligomer PET is preferable. The thickness of the weather-resistant substrate 4 is preferably 6 μm to 100 μm. If the thickness is less than 6 μm, the strength and weather resistance are insufficient, and if it exceeds 100 μm, thermal shrinkage increases, and the deformation of the solar cell wiring sheet is caused by the deformation of the aluminum layer. It is difficult to prevent due to the effect, and a cost problem arises.
＜接着剤層＞
本発明に係わる接着剤層は、２液硬化型のポリウレタン系接着剤が好ましい。また接着剤の塗布量は、乾燥後で３〜２０ｇ／ｍ２が望ましい。３ｇ／ｍ２未満では、接着強度の不足となり、２０ｇ／ｍ２を超えると接着強度などの問題はないが経済的ではない。
<Adhesive layer>
The adhesive layer according to the present invention is preferably a two-component curable polyurethane adhesive. The amount of adhesive applied is preferably 3 to 20 g / m 2 after drying. If it is less than 3 g / m 2 , the adhesive strength is insufficient. If it exceeds 20 g / m 2 , there is no problem such as adhesive strength, but it is not economical.
