Abstract
Description
本發明係關於一種使用於太陽能電池模組製造之隔膜片、使用隔膜片之太陽能電池模組的製造方法，及使用隔膜片之太陽能電池模組的積層方法。 The present invention relates to a diaphragm for manufacturing a solar cell module, a method for manufacturing a solar cell module using the separator, and a method for laminating a solar cell module using the separator.
一般於屋外所使用之太陽能電池單元，為了避免水分或灰塵的影響，又冰雹或小石子的撞擊，或耐風壓，而封入任意之容器或樹脂中之模組來使用。例如：被稱作為表層薄板一片構造之太陽能電池模組，係採用玻璃板與後座間封入太陽能電池單元和密封材的構造。密封材係使構成模組之構件彼此一體化，又隔絕太陽能電池單元對來自屋外的影響，且與太陽能電池之耐久性相關。作為密封材係廣泛地使用乙烯-醋酸乙烯酯樹脂製者。 The solar cell units generally used outside the house are used in order to avoid the influence of moisture or dust, the impact of hail or pebbles, or the resistance to wind pressure, and are enclosed in any container or resin. For example, a solar cell module, which is referred to as a surface sheet, is constructed by encapsulating a solar cell unit and a sealing material between a glass plate and a rear seat. The sealing material integrates the components constituting the module, and isolates the influence of the solar cell unit from the outside, and is related to the durability of the solar cell. As the sealing material, an ethylene-vinyl acetate resin is widely used.
太陽能電池模組係藉由積層裝置於真空下熱接著上述之各構件來製造。此熱接著之作業係於積層裝置內將經積層之模組構成構件夾持於隔膜片與加熱板之間，且使積層裝置內之特定空間為真空狀態，加熱板加熱，藉由熱溶解及熱交聯密封材來進行。 The solar cell module is manufactured by laminating a device under vacuum to follow the above-described members. The heat is then carried out in the layering device to sandwich the laminated module component between the diaphragm and the heating plate, and the specific space in the layering device is in a vacuum state, and the heating plate is heated by heat dissolution and The heat is crosslinked to the sealing material.
充分且均勻地進行密封材之熱交聯其為重要。若有密封材熱交聯不充分的部分，則由該部分產生模組構件彼此之剝離、濕氣侵入、太陽能電池單元之腐蝕。 It is important to carry out the thermal crosslinking of the sealing material sufficiently and uniformly. If there is a portion where the sealing material is not thermally crosslinked, peeling of the module members, moisture intrusion, and corrosion of the solar cell are caused by the portion.
就耐熱性之方面而言，先前隔膜片可廣泛使用聚矽氧橡膠(專利文獻1)。然而，由聚矽氧橡膠構成之隔膜片由於重複使用而各性能下降，有耐久性不充分等問題。 In terms of heat resistance, polyoxyxene rubber can be widely used as the separator sheet (Patent Document 1). However, the separator sheet made of polyoxyxene rubber has various performances due to repeated use, and has problems such as insufficient durability.
具體而言，重複使用隔膜片時，在隔膜片產生摺痕而於積層加工中無法均勻地加壓，且於積層加工中突然隔膜片破裂，而生成因隔膜片交換作業所產生之生產損耗、製造產率下降等問題。 Specifically, when the diaphragm sheet is repeatedly used, the diaphragm sheet is creased and cannot be uniformly pressurized during the laminating process, and the diaphragm sheet is suddenly broken during the laminating process, and the production loss due to the diaphragm sheet exchange operation is generated. Problems such as a decrease in manufacturing yield.

Figure. Fig. 3 shows the lamination process, and Fig. 4 shows the lamination process.
上殼110係形成有下方向開口之空間，與該開口面連接而設置有隔膜片112。上殼110內，利用隔膜片112形成分隔空間(上腔室113)。如後述，隔膜片112係作為緊壓被加工物10a之緊壓構件的功能，可積層被加工物10a。 The upper case 110 is formed with a space that opens in the lower direction, and is provided with a diaphragm piece 112 connected to the opening surface. In the upper casing 110, a partition space (upper chamber 113) is formed by the diaphragm piece 112. As will be described later, the diaphragm piece 112 functions as a pressing member for pressing the workpiece 10a, and the workpiece 10a can be laminated.
又，於上殼110之上面，設置有與上腔室113連通之吸排氣口114。經由吸排氣口114使上腔室113抽真空而成 為真空狀態，且可由上腔室113導入大氣壓。 Further, on the upper surface of the upper casing 110, an intake and exhaust port 114 communicating with the upper chamber 113 is provided. The upper chamber 113 is evacuated via the intake and exhaust port 114 It is in a vacuum state, and atmospheric pressure can be introduced from the upper chamber 113.
下殼120形成有上方向開口之空間(下腔室121)，於該空間設置有加熱板122(板狀之加熱器)。加熱板122係藉由於下殼120之底面設立的支撐構件，以保持水平狀態來支撐。此時，加熱板122係其表面以與下腔室121之開口面大致相同高度來支撐。 The lower case 120 is formed with a space in which the upper direction is opened (the lower chamber 121), and a heating plate 122 (a heater of a plate shape) is provided in the space. The heating plate 122 is supported by a support member provided by the bottom surface of the lower case 120 to maintain a horizontal state. At this time, the surface of the heating plate 122 is supported at substantially the same height as the opening surface of the lower chamber 121.
又，於下殼120之下面，設置有與下腔室121連通之吸排氣口123。經由吸排氣口123使下腔室121抽真空而成為真空狀態，且可由下腔室121導入大氣壓。 Further, an intake and exhaust port 123 communicating with the lower chamber 121 is provided below the lower casing 120. The lower chamber 121 is evacuated via the intake and exhaust port 123 to be in a vacuum state, and atmospheric pressure can be introduced from the lower chamber 121.
於上殼110與下殼120之間，在加熱板122的上方設置有可自由移動之搬送輪帶(belt)130。搬送輪帶130係自圖2之搬入輸送機200將被加工物10a搬送至積層部101之中央位置，積層後之被加工物(太陽能電池模組10b)由圖2之搬出輸送機300取出。 Between the upper casing 110 and the lower casing 120, a freely movable conveyor belt 130 is disposed above the heating plate 122. The conveyance belt 130 conveys the workpiece 10a to the center of the laminated portion 101 from the loading conveyor 200 of Fig. 2, and the laminated workpiece (the solar battery module 10b) is taken out by the carry-out conveyor 300 of Fig. 2 .
又，上殼110與下殼120之間，搬送輪帶130之上方設置有剝離片140。剝離片140係用於熔融被加工物10a之密封材13、14(參照圖1)時，防止密封材13、14附著於隔膜片112者。作為剝離片140，可使用表面經聚矽氧脫模劑處理之樹脂薄膜等。 Further, between the upper case 110 and the lower case 120, a peeling piece 140 is provided above the transfer belt 130. When the release sheet 140 is used to melt the sealing materials 13 and 14 of the workpiece 10a (see FIG. 1), the sealing members 13 and 14 are prevented from adhering to the separator sheet 112. As the release sheet 140, a resin film or the like whose surface is treated with a polyoxymethylene release agent can be used.
接著，針對使用本發明之隔膜片之積層步驟的實施形態更具體地進行說明。 Next, an embodiment of the step of laminating using the separator sheet of the present invention will be described more specifically.
首先，如圖3所示，利用搬送輪帶130，將被加工物10a搬送至積層部101之中央位置。又，藉由溫度控制器，將加熱板122之溫度控制為目標溫度。積層時之溫度通 常設為140~170℃。 First, as shown in FIG. 3, the workpiece 10a is conveyed to the center position of the laminated part 101 by the conveyance belt 130. Further, the temperature of the heating plate 122 is controlled to the target temperature by the temperature controller. Temperature through layer Standing for 140~170 °C.
接著，經由上殼110之吸排氣口114，進行上腔室113之抽真空。又，利用升降裝置(未圖示)使上殼110下降。藉由使上殼110下降，經由隔膜片，使上殼110與下殼120密合，且上腔室113及下腔室121分別保持密閉狀態。再者，於此狀態，去除周邊部分外之大部分的隔膜片係成為貼附於上腔室的狀態。 Next, evacuation of the upper chamber 113 is performed via the suction and exhaust port 114 of the upper casing 110. Further, the upper casing 110 is lowered by a lifting device (not shown). By lowering the upper case 110, the upper case 110 and the lower case 120 are brought into close contact via the diaphragm piece, and the upper chamber 113 and the lower chamber 121 are respectively kept in a sealed state. Further, in this state, most of the diaphragm sheets except the peripheral portion are removed from the upper chamber.
接著，經由下殼120之吸排氣口123，進行下腔室121之抽真空。藉由下腔室121之抽真空，而可去除被加工物10a所含之氣泡。進而，於此狀態下被加工物10a利用加熱板122進行加熱，使其內部所含之密封材13、14熔融。 Next, evacuation of the lower chamber 121 is performed via the suction and exhaust port 123 of the lower casing 120. The air bubbles contained in the workpiece 10a can be removed by vacuuming the lower chamber 121. Further, in this state, the workpiece 10a is heated by the heating plate 122 to melt the sealing members 13 and 14 contained therein.
接著，保持下腔室121之真空狀態，經由上腔室110之吸排氣口114，將大氣壓導入上腔室113。藉此，於上腔室113與下腔室121產生氣壓差，而隔膜片112膨脹，如圖4所示，隔膜片112被向下方擠壓。被加工物10a係利用向下方擠壓之隔膜片112而被擠壓，藉由熔融之密封材13、14來積層各構成構件。 Next, the vacuum state of the lower chamber 121 is maintained, and atmospheric pressure is introduced into the upper chamber 113 via the intake and exhaust port 114 of the upper chamber 110. Thereby, a difference in air pressure is generated in the upper chamber 113 and the lower chamber 121, and the diaphragm piece 112 is expanded, and as shown in Fig. 4, the diaphragm piece 112 is pressed downward. The workpiece 10a is pressed by the diaphragm piece 112 which is pressed downward, and the respective constituent members are laminated by the molten sealing members 13 and 14.
該積層步驟結束後，經由下殼120之吸排氣口123，將大氣壓導入下腔室121。又，利用升降裝置(未圖示)使上殼110上升。藉由使上殼110上升，如圖2所示，可使搬送輪帶130移動。搬送輪帶130係取出積層後之被加工物(太陽能電池模組10b)至搬出輸送機300。 After the laminating step is completed, atmospheric pressure is introduced into the lower chamber 121 through the intake and exhaust port 123 of the lower casing 120. Further, the upper casing 110 is raised by a lifting device (not shown). By raising the upper casing 110, as shown in Fig. 2, the conveyor belt 130 can be moved. The conveyance belt 130 takes out the layered workpiece (solar battery module 10b) to the carry-out conveyor 300.
又，於積層步驟，藉由以隔膜片對太陽能電池模組之構件加壓，提高各構件之接著度，因此如圖4所示之下腔室121較佳為可實現高真空度。 Further, in the laminating step, by pressing the members of the solar cell module with the diaphragm to increase the adhesion of the members, the lower chamber 121 is preferably made to have a high degree of vacuum as shown in FIG.
進而，就生產性的方面而言，於積層步驟，若真空度成為一定值以下之時間短，則期望真空度保持於一定之間。具體而言，就防止由密封固化所引起之模組內之氣泡殘存的方面而言，於積層時之抽真空步驟中，積層裝置之下腔室內的真空度達133Pa的時間較佳為120秒以下，更佳為100秒以下，再更佳為90秒以下。又，至步驟結束充分地保持真空度而防止模組內之氣泡混入的方面而言，於積層時之抽真空步驟中，積層裝置之下腔室內的真空度達133Pa後3分鐘過後之下腔室內的真空度較佳為100Pa以下，更佳為80Pa以下，再更佳為70Pa以下。 Further, in terms of productivity, in the laminating step, if the vacuum is less than or equal to a certain value, the degree of vacuum is desirably kept constant. Specifically, in terms of preventing the residual bubbles in the module caused by the curing of the seal, in the vacuuming step at the time of lamination, the vacuum in the chamber below the laminating device is preferably 133 Pa for 120 seconds. Hereinafter, it is more preferably 100 seconds or less, and still more preferably 90 seconds or less. Further, in the aspect of sufficiently maintaining the degree of vacuum at the end of the step to prevent the bubbles in the module from being mixed, in the vacuuming step at the time of laminating, the vacuum in the chamber below the laminating device reaches 133 Pa, and after 3 minutes, the cavity is lowered. The degree of vacuum in the room is preferably 100 Pa or less, more preferably 80 Pa or less, still more preferably 70 Pa or less.
後述之本發明之隔膜片係可實現上述條件。再者，於先前隔膜片所使用之聚矽氧橡膠，由於分子鍵結角較EPDM大且氣體穿透性高，故無法實現上述條件。 The above-described conditions can be achieved by the diaphragm sheet of the present invention described later. Further, in the polyoxyxene rubber used in the foregoing separator sheet, since the molecular bonding angle is larger than that of EPDM and the gas permeability is high, the above conditions cannot be achieved.
再者，上述之真空度係可利用實施例所記載之方法進行測定。 Further, the above vacuum degree can be measured by the method described in the examples.
密封材係以乙烯-醋酸乙烯酯樹脂(EVA)作為主成分，包含有機過氧化物或矽烷偶合劑等作為添加劑而成者。密封材係將包含EVA及添加劑之密封材組成物藉由成形且片狀化而得者。 The sealing material is made of ethylene-vinyl acetate resin (EVA) as a main component, and includes an organic peroxide or a decane coupling agent as an additive. The sealing material is obtained by forming and flaking a sealing material composition containing EVA and an additive.
乙烯-醋酸乙烯酯樹脂(EVA)係由乙烯與醋酸乙烯酯共聚而成者，通常醋酸乙烯酯成分為3~40mol%。 The ethylene-vinyl acetate resin (EVA) is a copolymer of ethylene and vinyl acetate, and usually has a vinyl acetate component of 3 to 40 mol%.
密封材之總重量成分中，EVA、有機過氧化物、矽烷偶合劑所佔之比例係EVA為92~98重量%，有機過氧化物為1~5重量%，矽烷偶合劑為1~3重量%左右。 Among the total weight components of the sealing material, the ratio of EVA, organic peroxide, and decane coupling agent is 92 to 98% by weight of EVA, 1 to 5% by weight of organic peroxide, and 1 to 3 weight of decane coupling agent. %about.
本發明人等，使用乙烯-丙烯-二烯橡膠(EPDM)作為隔膜片時，相對於EVA樹脂之熱交聯時產生之氣體，發現耐久性提升。進而本發明人等，發現由EPDM所構成之隔膜片滿足下述(1)、(2)之條件而有用， When the present inventors used ethylene-propylene-diene rubber (EPDM) as a separator sheet, it was found that the durability was improved with respect to the gas generated during thermal crosslinking of the EVA resin. Further, the present inventors have found that a separator sheet composed of EPDM is useful for satisfying the conditions (1) and (2) below.
(1)對於在乙烯-醋酸乙烯酯樹脂所含的交聯劑之膨潤率為20%以下，且對於矽烷偶合劑之膨潤率為20%以下。 (1) The swelling ratio of the crosslinking agent contained in the ethylene-vinyl acetate resin is 20% or less, and the swelling ratio of the decane coupling agent is 20% or less.
(2)加熱板溫度130℃下之隔膜片的殘痕性為3mm以下。 (2) The residual sheet of the separator sheet at a heating plate temperature of 130 ° C is 3 mm or less.
密封材，就太陽能電池模組之機械強度或與蓋玻璃之密合性的方面而言，除了EVA之外包含有機過氧化物及矽烷偶合劑。該等有機過氧化物及矽烷偶合劑，其係於製作太陽能電池模組之加熱積層時，可成為氣體放出至外部。隔膜片若吸收上述氣體所含之有機過氧化物及矽烷偶合劑，則隔膜片之物裡性質或化學性質慢慢地產生變化，且無法維持當初的性能。因此，隔膜片具有對有機過氧化物及矽烷偶合劑之耐性，具體而言，必須為對於有機過氧化物及矽烷偶合劑難以膨潤。 The sealing material contains an organic peroxide and a decane coupling agent in addition to EVA in terms of mechanical strength of the solar cell module or adhesion to the cover glass. The organic peroxide and the decane coupling agent can be released to the outside when the heating layer of the solar cell module is produced. When the separator absorbs the organic peroxide and the decane coupling agent contained in the gas, the properties or chemical properties of the separator are gradually changed, and the original performance cannot be maintained.

The residual mark refers to an index indicating the degree of deformation when the separator sheet is laminated, and can be measured by the method described in the examples.
若隔膜片之殘痕性超過3mm，則於連續地積層加工時，隔膜片之功能即均勻地抑制太陽能電池模組(構成構 件)無法進行。又，隔膜片之殘痕性超過3mm，則由殘痕造成之皺摺，因連續地加工而導致裂痕，而耐久性下降。因此，殘痕性為3mm以下，有其重要。 When the residual property of the separator sheet exceeds 3 mm, the function of the separator sheet uniformly suppresses the solar cell module during the continuous lamination processing (constitution) Pieces) cannot be performed. Further, when the residual property of the separator sheet exceeds 3 mm, the wrinkles caused by the residual marks cause cracks due to continuous processing, and the durability is lowered.

進而，就提高交聯效率之方面而言，亦可與交聯劑 一同使用共交聯劑。作為共交聯劑，可舉出：三聚異氰酸三烯丙酯(TAIC)、乙二醇二甲基丙烯酸酯(EG)、三羥甲基丙烷三甲基丙烯酸酯(TMP)等。 Further, in terms of improving the crosslinking efficiency, it is also possible to form a crosslinking agent. A co-crosslinking agent is used together. Examples of the co-crosslinking agent include triallyl isocyanurate (TAIC), ethylene glycol dimethacrylate (EG), and trimethylolpropane trimethacrylate (TMP).

隔膜片，係例如：將經混合之EPDM組成物(除交聯劑及共交聯劑外)的化合物成型後，於化合物中添加交聯劑(視需要進而添加共交聯劑)，藉由片狀化來製造。 The separator sheet is, for example, a compound obtained by mixing the mixed EPDM composition (except the crosslinking agent and the co-crosslinking agent), and then adding a crosslinking agent (if necessary, adding a co-crosslinking agent) to the compound, by Sheeting to make.
通常於化合物中添加交聯劑且將其片狀成型時係於160℃左右之溫度進行成型加工，此溫度為交聯EPDM之長時間所需。若交聯時間過短，則交聯劑殘留於隔膜片中，於製造太陽能電池模組之製造時，EPDM交聯之結果，使殘痕性難以為3mm以下。 Usually, a crosslinking agent is added to the compound, and when it is formed into a sheet shape, it is subjected to a molding process at a temperature of about 160 ° C, which is required for the long time of crosslinking the EPDM. When the crosslinking time is too short, the crosslinking agent remains in the separator sheet, and as a result of the crosslinking of the EPDM in the production of the solar cell module, it is difficult to make the residual traceability 3 mm or less.
因此，就殘痕性之方面而言，隔膜片之成型溫度較佳為170℃以上，更佳為180℃以上。又，此時，成型時間較佳為5分鐘以上，更佳為10~50分鐘。 Therefore, in terms of the residue, the molding temperature of the separator sheet is preferably 170 ° C or higher, more preferably 180 ° C or higher.

The words are more appropriate.
又，使用有機過氧化物作為交聯劑時，就防止有機 過氧化物殘留於隔膜片中的方面而言，較佳為於隔膜片之成型時或成型後，包含有機過氧化物充分地分解之熱處理步驟。有機過氧化物，就於半衰期6~7倍的時間大致分解而言，較佳為例如：於隔膜片之成型時或成型後，包含於1分鐘半衰期溫度以上加熱6分鐘以上之步驟。 Also, when using an organic peroxide as a crosslinking agent, it prevents organic In the aspect in which the peroxide remains in the separator sheet, it is preferred to include a heat treatment step in which the organic peroxide is sufficiently decomposed at the time of molding or after molding of the separator sheet. The organic peroxide is preferably subjected to a step of heating at a half-life of 1 minute or more for 6 minutes or more at the time of molding or after molding of the separator sheet in the case where the half-life is substantially 6 to 7 times.
