此匯流製程涉及取小片段之匯流帶108並將其焊接至鍍錫銅帶106之末端。此匯流製程通常藉由手工使用焊接鐵而完成且代表在製造光伏打模組100時的費工製程。匯流帶108亦在此階段焊接至光伏打模組上以提供與接線盒112之電性連接。第2圖所示之匯流帶108之90度彎曲的彎頭120係藉著彎曲匯流帶108或以直角互相焊接兩塊匯流帶108兩者之一而製成。This sinking process involves taking a small segment of the busbar 108 and soldering it to the end of the tinned copper strip 106. This sinking process is typically accomplished by manual use of soldered iron and represents a labor-intensive process in the fabrication of photovoltaic modules 100. The busbar 108 is also soldered to the photovoltaic module at this stage to provide an electrical connection to the junction box 112. The 90 degree curved elbows 120 of the bus bar 108 shown in Fig. 2 are made by bending the bus bar 108 or welding one of the two bus bars 108 at right angles.
在匯流製程中，在執行焊接時必須小心以避免鎔化封裝材料之第一薄板。此外，在第2圖所示之匯流帶108交會處或交叉處122亦必須小心不造出電性短路。此係藉著放置小片段之乙烯乙酸乙烯酯或背板於匯流帶108在有交叉處之各位置122之間所達成。這樣精巧的步驟通常增加了可觀的時間及對製造製程的風險。In the confluence process, care must be taken when performing the soldering to avoid deuteration of the first sheet of encapsulation material. In addition, care must be taken not to create an electrical short at the intersection or intersection 122 of the busbar 108 shown in FIG. This is accomplished by placing small pieces of ethylene vinyl acetate or a backsheet between the confluences 108 at locations 122 where there are intersections. Such elaborate steps often add considerable time and risk to the manufacturing process.
4.第二次疊合4. The second overlap
a.放置封裝材料(如乙烯乙酸乙烯酯)之第二薄板於疊合的光伏打電池104上。此步驟通常藉著手工執行，其中需多加小心不會無意間移動疊合的光伏打電池104。此外，用於連接至接線盒112的匯流帶108係佈置以穿過以封裝材料之第二薄板所製成之狹縫124。a. A second sheet of encapsulating material, such as ethylene vinyl acetate, is placed over the laminated photovoltaic cells 104. This step is usually performed by hand, with care being taken not to inadvertently move the stacked photovoltaic cells 104. Further, the bus bar 108 for connection to the junction box 112 is arranged to pass through the slit 124 made of the second sheet of the encapsulating material.
b.放置背板(如商標Tedlar或類似所製成)於封裝材料之第二薄板之背面。並再度多加小心不要無意間移動疊合的光伏打電池104。此外，用於連接至接線盒112的匯流帶108係佈置以穿過以背板所製成之狹縫124。b. A backing plate (such as the trademark Tedlar or the like) is placed on the back of the second sheet of packaging material. And again, be careful not to inadvertently move the stacked photovoltaic cells 104. Further, the bus bar 108 for connection to the junction box 112 is arranged to pass through the slit 124 made of the back plate.
5. 貼合(lamination)5. Lamination
a.貼合光伏打模組100。貼合製程包含熔解及交聯封裝材料並接合所有組件在一起(即玻璃、封裝材料、光伏打電池、悍帶(ribbon)及背板)。a. Fit the photovoltaic module 100. The lamination process involves melting and cross-linking the encapsulating material and joining all of the components together (ie, glass, encapsulating material, photovoltaic cells, ribbons, and backsheets).
6.定框6. Box
a.以刀修整光伏打積層之邊緣周圍多餘的封裝材料及背板。a. Use a knife to trim excess packaging material and backsheet around the edge of the PV stack.
b.取四個框架元件並施與灌封劑(通常是矽酮橡膠(silicone rubber))至四個框架元件之溝槽中。b. Take four frame elements and apply a potting agent (usually silicone rubber) to the grooves of the four frame elements.
c.放置護角於框架元件之框角。c. Place the corners on the frame corners of the frame elements.
d.放置四個框架元件及光伏打積層於定框壓台。d. Place four frame elements and photovoltaic build-up layers on the framed press table.
e.啟動定框壓台以固定環繞光伏打積層之框架元件。e. Start the framed press to secure the frame elements surrounding the photovoltaic buildup.
f.拭去任何自框架元件與光伏打積層之間擠壓而溢出的灌封劑。f. Wipe off any potting agent that is squeezed from between the frame element and the photovoltaic buildup layer.
7.接線盒7. Junction box
a.繞著接線盒112之邊緣施與灌封劑並固定接線盒112至光伏打模組100的背板。a. Apply potting agent around the edge of the junction box 112 and secure the junction box 112 to the backing plate of the photovoltaic module 100.
b.連接接線盒悍帶至接線盒(根據所使用的特定接線盒之構造而藉著焊接亦或特別設計之角夾之兩者之一)。b. Connect the junction box to the junction box (either by soldering or one of the specially designed corner clips depending on the configuration of the particular junction box used).
因此，其可見到上述之製造光伏打模組100的傳統方法涉及一些費工及精巧的步驟，像是匯流及定框步驟。光伏打積層定框後固定接線盒112至光伏打模組100之背板之需求增加了額外的生產時間至製造製程。除了費工外，由於容易有人為疏失(如在焊接匯流帶時)，這些步驟亦引入一些可能造成生產延遲或減少產量之風險至製造製程中。僅管一些上述步驟可自動化以減少製造時間，然而，由於需要大量的資本投入以及關於維持機械之額外接續成本，此可能使人望而卻步。Thus, it can be seen that the conventional method of fabricating a photovoltaic module 100 described above involves some laborious and ingenious steps, such as confluence and framing steps. The need to fix the junction box 112 to the backsheet of the photovoltaic module 100 after the photovoltaic buildup has been framed adds additional production time to the manufacturing process. In addition to labor, due to the ease of human error (such as when welding the busbar), these steps also introduce some risks that may cause production delays or reduce production to the manufacturing process. Although some of the above steps can be automated to reduce manufacturing time, however, this can be prohibitive due to the large capital investment required and the additional cost of maintaining the machine.
本發明之實施例係尋求突破，或至少改善一或多種上述問題。Embodiments of the present invention seek to break through, or at least ameliorate one or more of the above problems.
第3圖繪示根據本發明之第一例示性實施例的光伏打模組(或太陽能面板)300之分解背視圖。光伏打模組300包含用於透過光伏打效應而轉換光或太陽能至電能之光伏打電池304之陣列302。在光伏打模組300中，光伏打電池304之各縱列係藉著一或多個導電線306而互聯，從而形成對應之光伏打電池304的系列308。對本技術領域具有通常知識者將了解的是，依據光伏打模組300之配向，第3圖中光伏打電池304之縱列可替代為光伏打電池304之橫排。因此，光伏打電池之陣列302具有一或多個導電線306與其固定。在較佳實施例中，導電線306係鍍錫銅帶(tabbing ribbons) (亦習知為串接帶(stringing ribbons))。在例示性光伏打模組300中，僅為了說明之目的，三個系列的導電線306係顯示為固定至光伏打電池304之縱列。對所技術領域具有相當知識者來說顯而易見的是，為了各種不同理由，更多或更少的導電線306之系列可如預期般固定至光伏打電池304之縱列。3 is an exploded rear view of a photovoltaic module (or solar panel) 300 in accordance with a first exemplary embodiment of the present invention. Photovoltaic module 300 includes an array 302 of photovoltaic cells 304 for converting light or solar energy to electrical energy through photovoltaic effects. In the photovoltaic module 300, the columns of the photovoltaic cells 304 are interconnected by one or more conductive lines 306 to form a series 308 of corresponding photovoltaic cells 304. It will be appreciated by those of ordinary skill in the art that, depending on the alignment of the photovoltaic modules 300, the column of photovoltaic cells 304 in FIG. 3 can be substituted for the horizontal rows of photovoltaic cells 304. Thus, the photovoltaic cell array 302 has one or more conductive lines 306 secured thereto. In the preferred embodiment, conductive lines 306 are tabbing ribbons (also known as stringing ribbons). In the exemplary photovoltaic module 300, three series of conductive lines 306 are shown as being fixed to the column of photovoltaic cells 304 for illustrative purposes only. It will be apparent to those of ordinary skill in the art that, for a variety of different reasons, a greater or lesser series of conductive lines 306 can be secured to the column of photovoltaic cells 304 as desired.
例示性光伏打模組300包含複數個外圍組件310設置相鄰於光伏打電池304之陣列302之各側邊312。在第一例示性實施例中，光伏打模組300包含四個外圍組件310設置相鄰於光伏打電池304之陣列302的四個各別側邊312，如頂部、底部、左側、右側外圍組件310。在完成之光伏打模組300中，為了定框光伏打電池304之陣列302，四個外圍組件310係一起互聯，最好是機械性地於其各末端。在此方面，外圍組件310可視為用於定框光模組300之框架組件。然而，對所屬技術領域具有通常知識者來說顯而易見的是依據將製造之光伏打模組的種類可提供少於四個的外圍組件310。舉例來說，用於玻璃-玻璃型的光伏打模組(圖未示)，僅有兩個外圍組件310(如頂部及底部外圍組件311、313)可提供相鄰於光伏打模組300之相對側邊312。在較佳實施例中，外圍組件310係為電性絕緣材料。舉例來說，外圍組件310可為注射模製。The exemplary photovoltaic module 300 includes a plurality of peripheral components 310 disposed adjacent respective sides 312 of the array 302 of photovoltaic cells 304. In the first exemplary embodiment, the photovoltaic module 300 includes four peripheral components 310 disposed adjacent to four respective sides 312 of the array 302 of photovoltaic cells 304, such as top, bottom, left, and right peripheral components. 310. In the completed photovoltaic module 300, in order to frame the array 302 of photovoltaic cells 304, the four peripheral components 310 are interconnected together, preferably mechanically at their respective ends. In this regard, the peripheral component 310 can be considered a frame assembly for the framing optical module 300. However, it will be apparent to those of ordinary skill in the art that fewer than four peripheral components 310 can be provided depending on the type of photovoltaic module to be fabricated. For example, for a glass-glass type photovoltaic module (not shown), only two peripheral components 310 (such as top and bottom peripheral components 311, 313) can be provided adjacent to the photovoltaic module 300. Opposite side 312. In the preferred embodiment, peripheral component 310 is an electrically insulating material. For example, the peripheral component 310 can be injection molded.
在如第3圖所示之例示性光伏打模組300中，兩個相對的外圍組件310(如頂部及底部外圍組件311、313)包含形成於其中之連接器元件314，每一個係配置或適用於機械性互聯至固定於光伏打電池304之陣列302的導電線306，以形成電性連接。連接器元件314係固定或整合於外圍組件310中。亦即，其係於外圍組件310中事先製備。舉例來說，連接器元件314可為連接夾或任何能夠保持放置於其中之電線之裝置，以形成電性連接。在例示性光伏打模組300中，外圍組件310中連接器元件314之元件組315對應至光伏打電池304之系列308。僅藉由第3圖所示之示例，元件組315包含配置用於接收固定於光伏打電池304之相對應系列308之三個對應之導電線306的三個連接器元件314。在外圍組件310中，預定之連接器元件314之相鄰元件組315係透過導電元件316而事先互聯在一起。舉例來說，導電元件316可為導電線或金屬沖壓件。在較佳實施例中，在外圍組件310中的導電元件316係為電性匯流器。因此，藉著透過電性匯流器316預先互聯(即在組裝或製造光伏打模組300之前)連接器元件314之適當的元件組315，外圍組件310係較有利的具有整合之匯流器。因此，可排除於一般傳統方法中涉及用於連接系列的光伏打電池在一起所需要的焊接之匯流製程。In an exemplary photovoltaic module 300 as shown in FIG. 3, two opposing peripheral components 310 (such as top and bottom peripheral components 311, 313) include connector elements 314 formed therein, each configured or It is suitable for mechanical interconnection to conductive lines 306 that are fixed to array 302 of photovoltaic cells 304 to form an electrical connection. Connector component 314 is fixed or integrated in peripheral component 310. That is, it is prepared in advance in the peripheral component 310. For example, the connector component 314 can be a connector clip or any device capable of holding an electrical wire placed therein to form an electrical connection. In the exemplary photovoltaic module 300, the component set 315 of the connector component 314 in the peripheral component 310 corresponds to the series 308 of photovoltaic cells 304. With only the example shown in FIG. 3, component set 315 includes three connector elements 314 configured to receive three corresponding conductive lines 306 that are fixed to corresponding series 308 of photovoltaic cells 304. In the peripheral component 310, adjacent component sets 315 of the predetermined connector component 314 are interconnected in advance through the conductive component 316. For example, conductive element 316 can be a conductive wire or a metal stamping. In the preferred embodiment, the conductive element 316 in the peripheral component 310 is an electrical combiner. Thus, by pre-interconnecting (i.e., prior to assembling or manufacturing the photovoltaic module 300) the appropriate component set 315 of the connector component 314 through the electrical combiner 316, the peripheral component 310 advantageously has an integrated combiner. Therefore, it is possible to exclude the conventional confluence process involving the welding required to connect the series of photovoltaic cells together.
在例示性光伏打模組300中，連接器元件314之元件組315係藉著導電元件316而互聯，使得在光伏打電池304之陣列302的導電線306之末端接附或夾於其中時，光伏打電池304相鄰之系列308係連接成一串聯，從而使在各系列之光伏打電池所產生之電流流至光伏打模組300的電性輸出端。因此，預定的連接器元件314之相鄰元件組係不用藉著導電元件316而互聯以達到這樣的電流流通。藉著如第3圖所示之示例，在外圍組件310中連接器元件314之交替之相鄰對元件組315係不用藉由導電元件316而互聯。更進一步，交替之相鄰對元件組315係佈置以使得在一個外圍組件310中連接器元件314之相鄰對元件組315(對應至光伏打電池304之相鄰對系列308)係不用藉由導電元件316而互聯，而在相對之外圍組件310中連接器元件314之相對相鄰對元件組315(對應至光伏打電池304之相同相鄰對系列308)係藉著導電元件316而互聯。在上述兩個相對外圍組件310之其中之一(如頂部外圍組件311)中，係提供一或多個二極體318事先互聯於連接器元件314之一或多個預定元件組315之間。舉例來說，二極體318係提供於連接器元件314之相鄰元件組315之間而非如上所述藉著導電元件316而互聯。最好是，二極體318係為用於使電流繞過無法產生足夠電流之光伏打電池304之系列308 (如系列的光伏打電池可能為被屏蔽區域)的旁通二極體。In the exemplary photovoltaic module 300, the component sets 315 of the connector elements 314 are interconnected by conductive elements 316 such that when the ends of the conductive lines 306 of the array 302 of photovoltaic cells 304 are attached or clamped therein, The series 308 of adjacent photovoltaic cells 304 are connected in series so that the current generated by the photovoltaic cells of each series flows to the electrical output of the photovoltaic module 300. Thus, adjacent component groups of predetermined connector elements 314 are not interconnected by conductive elements 316 to achieve such current flow. By way of example as shown in FIG. 3, alternating pairs of adjacent pairs of elements 315 of connector elements 314 in peripheral component 310 are not interconnected by conductive elements 316. Further, alternating pairs of adjacent pairs of elements 315 are arranged such that adjacent pairs of elements 315 of connector elements 314 (corresponding to adjacent pairs of series 308 of photovoltaic cells 304) in one peripheral component 310 are not The conductive elements 316 are interconnected, and in the opposite peripheral component 310, the relatively adjacent pair of component sets 315 of connector elements 314 (corresponding to the same adjacent pair of series 308 of photovoltaic cells 304) are interconnected by conductive elements 316. In one of the two opposing peripheral components 310 (e.g., top peripheral component 311), one or more diodes 318 are provided that are interconnected in advance between one or more predetermined component sets 315 of connector elements 314. For example, diodes 318 are provided between adjacent component sets 315 of connector elements 314 and are not interconnected by conductive elements 316 as described above. Preferably, the diode 318 is a bypass diode for bypassing a series 308 of photovoltaic cells 304 that are unable to generate sufficient current (e.g., a series of photovoltaic cells may be shielded regions).
在較佳實施例中，如第3圖所示之提供或整合於外圍組件310之其中之一的連接器元件314、導電元件316及二極體318之互聯係配置以作用為在外圍組件310中之接線盒。因此，其有利地不再需要如一般傳統方法中需要的最後步驟去固定接線盒至光伏打模組。亦即，外圍組件310(如頂部外圍組件311)可視為具有整合的匯流器及具有整合的接線盒。In a preferred embodiment, the inter-connected configuration of connector element 314, conductive element 316, and diode 318, which are provided or integrated in one of peripheral components 310, as shown in FIG. 3, functions to function at peripheral component 310. The junction box in the middle. Therefore, it is advantageously no longer necessary to fix the junction box to the photovoltaic module as the last step required in the conventional conventional method. That is, the peripheral component 310 (eg, the top peripheral component 311) can be considered to have an integrated combiner and have an integrated junction box.
所屬技術領域具有通常知識者將了解光伏打模組300的分解圖係如第3圖所示。因此，導電線306並不顯示為與對應之連接器元件314連接。所屬技術領域具有通常知識者將了解如上所述之導電線306係為了與其形成對應電性連接而於兩個相對外圍組件310中連接至對應之連接器元件314。Those skilled in the art will appreciate that the exploded view of the photovoltaic module 300 is as shown in FIG. Thus, the conductive lines 306 are not shown as being coupled to corresponding connector elements 314. Those of ordinary skill in the art will appreciate that the conductive lines 306 as described above are coupled to corresponding connector elements 314 in two opposing peripheral components 310 for forming a corresponding electrical connection therewith.
在第一例示性光伏打模組300中，各個外圍組件310更包含用於相互連接或固定外圍組件310之第一連接器組件326於其相對末端。舉例來說，第一連接器組件326在相互互聯外圍組件310時可以嵌合型連接器對之形式藉著公連接器設置於外圍組件310之一端而母連接器設置於相鄰之外圍組件310之一端以相互固定。在較佳實施例中，第一連接器組件326係為夾型的，從而使對應之第一連接器組件326透過推力之應用而為機械性地相互互聯。結果，外圍組件310可藉著於其適當末端“夾”在一起而相對快速且輕易地相互互聯。In the first exemplary photovoltaic module 300, each peripheral component 310 further includes a first connector component 326 for interconnecting or securing the peripheral component 310 at its opposite end. For example, the first connector component 326 can be disposed at one end of the peripheral component 310 by the male connector and the female connector is disposed adjacent to the peripheral component 310 by the male connector when the peripheral component 310 is interconnected. One end is fixed to each other. In the preferred embodiment, the first connector assemblies 326 are clip-type such that the corresponding first connector assemblies 326 are mechanically interconnected by the application of thrust. As a result, peripheral components 310 can be interconnected relatively quickly and easily by "clamping" them together at their appropriate ends.
在較佳實施例中，兩個相對的外圍組件310(如頂部及底部外圍組件311、313)，各更包含第二連接器組件320於其相對末端。第二連接器組件320係配置以與另一個(如相鄰的)光伏打模組(圖未示)之外圍組件之對應的連接器組件互聯。因此，根據本實施例此使光伏打模組300能夠相互互聯以形成光伏打系統。第二連接器組件320可為能夠機械性地與另一個外圍組件(圖未示)的對應之連接器組件直接或透過中介連接器組件322兩者之一而互聯的任何型類。舉例來說，相鄰之光伏打模組300可以中介連接器組件322藉著機械性地互聯相鄰光伏打模組的各別相對外圍組件310而相互固定。舉例來說，第二連接器組件320可為母連接器且中介連接器組件322可為公連接器配置以機械性地相互互聯。進一步地，兩個相對之外圍組件310之其中之一(如頂部外圍組件311)的第二連接器組件320係進一步地與外圍組件310中的連接器元件314電性互聯，以與光伏打電池304之陣列302電性互聯。因此，如頂部外圍組件311之第二連接器組件320進一步地作用以電性互聯光伏打電池304之陣列302或光伏打模組300與相鄰之光伏打模組，以形成電性互連之光伏打系統。在此方面，舉例來說，中介連接器組件322係為電傳導性。所屬技術領域具有通常知識者將了解一或多種第二連接器組件320亦可作用為光伏打模組或系統(如在光伏打系統中最後之光伏打模組)之電性輸出端。舉例來說，第二連接器組件320可連接至電纜324之連接器終端323，以連接至像是變流器(圖未示)或其他系列的光伏打模組(圖未示)之輸出電路。In the preferred embodiment, two opposing peripheral components 310 (such as top and bottom peripheral components 311, 313) each further include a second connector component 320 at an opposite end thereof. The second connector component 320 is configured to interconnect with a corresponding connector component of a peripheral component of another (eg, adjacent) photovoltaic module (not shown). Thus, in accordance with this embodiment, the photovoltaic modules 300 can be interconnected to form a photovoltaic system. The second connector component 320 can be any type that can be mechanically interconnected with one or more of the corresponding connector components of another peripheral component (not shown). For example, adjacent photovoltaic modules 300 can be secured to each other by interposing connector assemblies 322 by mechanically interconnecting respective opposing peripheral components 310 of adjacent photovoltaic modules. For example, the second connector component 320 can be a female connector and the mediation connector component 322 can be configured for a male connector to be mechanically interconnected. Further, the second connector component 320 of one of the two opposing peripheral components 310 (eg, the top peripheral component 311) is further electrically interconnected with the connector component 314 of the peripheral component 310 to electrically charge the battery The array 302 of 304 is electrically interconnected. Therefore, the second connector component 320, such as the top peripheral component 311, further functions to electrically interconnect the array 302 of photovoltaic cells 304 or the photovoltaic module 300 with adjacent photovoltaic modules to form an electrical interconnection. Photovoltaic system. In this regard, for example, the interposer connector component 322 is electrically conductive. Those of ordinary skill in the art will appreciate that one or more of the second connector assemblies 320 can also function as an electrical output for a photovoltaic module or system (e.g., the last photovoltaic module in a photovoltaic system). For example, the second connector assembly 320 can be coupled to the connector terminal 323 of the cable 324 for connection to an output circuit such as a current transformer (not shown) or other series of photovoltaic modules (not shown). .
根據本發明之第二例示性實施例，其係提供位於光伏打電池304之陣列302之側邊312用於互聯固定至光伏打電池304之陣列302的一或多個導電線的外圍組件310。外圍組件310係與上文第一實施例所述之相同，且因此為了簡潔起見將不再重複。舉例來說，在製造玻璃-封裝材料-背板型光伏打模組時，四個外圍組件310可設置相鄰於光伏打電池304之陣列302的各四個側邊312，且接著機械性地相互互聯於一起，從而形成剛性的矩形結構用於定框光伏打電池304之陣列302。在此方面，外圍組件310可視為用於定框光伏打模組300之框架組件。此外，在製造玻璃-玻璃型光伏打模組時，兩個相對的外圍組件311、313可放置相鄰於光伏打電池304 之陣列302之各別相對之兩側邊。如前所述，頂部外圍組件311包含用於電性及機械性地互聯相鄰之光伏打模組於一起的第二連接器組件320。In accordance with a second exemplary embodiment of the present invention, a peripheral component 310 is provided on one side 312 of the array 302 of photovoltaic cells 304 for interconnecting one or more conductive lines that are secured to the array 302 of photovoltaic cells 304. The peripheral component 310 is the same as described in the first embodiment above, and thus will not be repeated for the sake of brevity. For example, in fabricating a glass-encapsulated material-backplane photovoltaic module, four peripheral components 310 can be disposed adjacent each of the four sides 312 of the array 302 of photovoltaic cells 304, and then mechanically Interconnected together to form a rigid rectangular structure for array 302 of photovoltaic photovoltaic cells 304. In this regard, the peripheral component 310 can be considered a frame assembly for the framing photovoltaic module 300. In addition, in the fabrication of the glass-glass photovoltaic module, two opposing peripheral components 311, 313 can be placed adjacent the respective opposite sides of the array 302 of photovoltaic cells 304. As previously discussed, the top peripheral component 311 includes a second connector component 320 for electrically and mechanically interconnecting adjacent photovoltaic modules.
如上文參照第1圖及第2圖所述，一般製造光伏打模組之傳統方法需要使用匯流帶而焊接系列的光伏打電池在一起於其末端的匯流製程，且接著藉由疊合製程及貼合製程以貼合光伏打模組。光伏打電池積層係接續定框並接著藉著固定其接線盒至光伏打模組而完成。如所說明之上述步驟係費工且耗時。本發明之實施例尋求藉由提供如本發明第一實施例及第二實施例所述之具有整合匯流器之複數個外圍組件310來解決這些問題。此外，外圍組件310之至少其一更具有整合於其中之接線盒之功能。因此，根據本發明之實施例之外圍組件310具有整合之匯流器及接線盒。結果，可自製造製程排除匯流步驟及固定接線盒至光伏打模組之步驟兩者，從而大幅地簡化製造製程且結果節省了大量人工勞力。As described above with reference to Figures 1 and 2, the conventional method of manufacturing photovoltaic modules generally requires the use of a busbar to solder a series of photovoltaic cells together at their ends, and then by a stacking process and The bonding process is adapted to fit the photovoltaic module. The photovoltaic cell stacking is continued and then completed by fixing its junction box to the photovoltaic module. The above steps as illustrated are laborious and time consuming. Embodiments of the present invention seek to address these problems by providing a plurality of peripheral components 310 having integrated combiners as described in the first and second embodiments of the present invention. In addition, at least one of the peripheral components 310 has a function of a junction box integrated therein. Thus, peripheral component 310 in accordance with an embodiment of the present invention has an integrated combiner and junction box. As a result, both the confluence step and the steps of fixing the junction box to the photovoltaic module can be eliminated from the manufacturing process, thereby greatly simplifying the manufacturing process and as a result, saving a lot of labor.
根據本發明之第三實施例，一種製造如第3圖所示之光伏打模組300之例示性方法現將參照第4圖而說明。此方法包含設置相鄰於光伏打電池304之陣列302之各側邊的複數個外圍組件310之起始步驟400。舉例來說，在製造像是第3圖所示之玻璃-封裝材料-背板型光伏打模組時，四個外圍組件310可設置相鄰於光伏打電池304之陣列302之各別四個側邊。此外，在製造玻璃-玻璃型光伏打模組(圖未示)時，兩個相對之外圍組件310可設置相鄰於光伏打電池304之陣列302之各別相對之兩側邊。接著，在步驟402中，固定於光伏打電池304之陣列302的導電線係連接至外圍組件310之對應連接器元件314，從而形成其對應之電性連結。因此，步驟404中，陣列的光伏打電池與連接至外圍組件之對應之連接器元件314的導電線306係被貼合。貼合製程係為所屬技術領域者所習知且因此將為了簡潔而不予於說明。In accordance with a third embodiment of the present invention, an exemplary method of fabricating a photovoltaic module 300 as shown in FIG. 3 will now be described with reference to FIG. The method includes an initial step 400 of setting a plurality of peripheral components 310 adjacent each side of the array 302 of photovoltaic cells 304. For example, in fabricating a glass-encapsulated material-backplane type photovoltaic module as shown in FIG. 3, four peripheral components 310 may be disposed adjacent to each of the array 302 of photovoltaic cells 304. Side. In addition, in the manufacture of a glass-glass photovoltaic module (not shown), two opposing peripheral components 310 can be disposed adjacent to opposite sides of the array 302 of photovoltaic cells 304. Next, in step 402, the conductive lines secured to the array 302 of photovoltaic cells 304 are coupled to corresponding connector elements 314 of the peripheral component 310 to form their corresponding electrical connections. Thus, in step 404, the photovoltaic cells of the array are bonded to the conductive lines 306 of the corresponding connector elements 314 that are connected to the peripheral components. The lamination process is well known to those skilled in the art and will therefore not be described for the sake of brevity.

Those skilled in the art will appreciate that this method is not limited to these specific examples. for example. Specific elements may be used in the following examples for purposes of explanation, but the invention is not limited to such specific elements.

The stringing process (also known as tabbing) is well known to those skilled in the art and therefore need not be described herein.
然而，由於外圍組件310具有於其中內建或整合之匯流器316，此有利地使得在各系列308中延伸自第一個及最後一個光伏打電池304的導電帶306之長度能夠等同於第1圖所示之所有系列308。此非針對第1圖所示之範例的傳統技術之情況。根據本發明之例示性實施例此代表非人工修整之導電帶306。However, since the peripheral component 310 has a combiner 316 built in or integrated therein, this advantageously allows the length of the conductive strip 306 extending from the first and last photovoltaic cells 304 in each series 308 to be equivalent to the first All series 308 shown in the figure. This is not the case with the conventional technology of the example shown in Fig. 1.

4.貼合4. Fit
a.貼合光伏打模組300。此步驟包含熔解及交聯封裝材料並接合所有組件在一起(即玻璃、封裝材料、光伏打電池、悍帶、框架及背板)。此貼合製程係為所屬技術領域者所習知且因此不需於此詳述。a. Fit the photovoltaic module 300. This step involves melting and crosslinking the encapsulating material and joining all of the components together (ie, glass, encapsulating material, photovoltaic cells, ribbons, frames, and backsheets). This lamination process is well known to those skilled in the art and therefore need not be described in detail herein.
製造玻璃-玻璃型光伏打模組之具或不具封裝材料於玻璃層之間之其中之一的非限制性範例現將根據本發明之實施例於下文中說明。Non-limiting examples of making glass-glass photovoltaic modules or having no packaging material between the glass layers will now be described below in accordance with embodiments of the present invention.

f.鋪置第二玻璃薄板於第二封裝薄板或光伏打電池304之陣列302上。f. Laying a second glass sheet onto the array 302 of second package sheets or photovoltaic cells 304.
3.疊合3. Overlay
a.疊合光伏打模組300。舉例來說，此可藉著熱層合(thermal lamination)或紫外線固化而達成。疊合製程係為所屬技術領域者所習知且因此不需於此詳述。a. The photovoltaic module 300 is superposed. This can be achieved, for example, by thermal lamination or UV curing. The lamination process is well known to those skilled in the art and therefore need not be described in detail herein.
因此，根據於前所述之本發明之實施例，大部分光伏打模組製造製程之費工步驟，即匯流、定框及接線盒之固定，已要不完全排除否則就是大幅地簡化，結果則是大幅地節省了成本及時間。Therefore, according to the embodiments of the present invention described above, the labor-consuming steps of most photovoltaic module manufacturing processes, that is, the convergence of the bus, the frame, and the junction box, have not been completely eliminated, otherwise the result is greatly simplified. This is a significant saving in cost and time.
現將說明根據本發明之實施例對於光伏打模組300或外圍組件310的附加優點或改善處。Additional advantages or improvements to the photovoltaic module 300 or peripheral component 310 in accordance with embodiments of the present invention will now be described.
在實施例中，外圍組件310可具有減少之配置以緊緊相附於玻璃板周圍。結果，外圍組件310沒有環繞邊緣且並不位於玻璃板之前表面(一般傳統光伏打模組之設計特徵)，而一旦安裝光伏打模組，該特徵會由於讓水聚集在光伏打模組表面之下邊緣而造成玻璃蓋之髒汙。此種髒汙將藉由本實施例由於光伏打模組表面上之水不被困住而可流失於邊緣而被完全地排除。In an embodiment, the peripheral component 310 can have a reduced configuration to closely attach around the glass sheet. As a result, the peripheral component 310 has no surrounding edge and is not located on the front surface of the glass plate (generally the design features of the conventional photovoltaic module), and once the photovoltaic module is installed, the feature is due to the accumulation of water on the surface of the photovoltaic module. The bottom edge causes the glass cover to be dirty. Such soiling will be completely eliminated by the present embodiment because the water on the surface of the photovoltaic module is not trapped and can be lost to the edge.
如前所述，由於沒有固定至光伏打模組300背部之接線盒，此模組框架(外圍組件310)可以較薄輪廓製成，使堆疊之模組佔據較少空間。此外，外圍組件310或框架可具有配置用於在傳輸中輕易且安全地堆疊模組之護角。此移除了對於具鋁輪廓框架之傳統光伏打模組所使用之特定堆疊夾之需求。進一步地，外圍組件或框架可在預定位置另外於其中具有孔洞以助於模組之簡易安裝。As previously mentioned, since there is no junction box secured to the back of the photovoltaic module 300, the module frame (peripheral component 310) can be made with a thin profile such that the stacked modules take up less space. Additionally, the peripheral component 310 or frame may have a corner guard configured to easily and safely stack the modules during transport. This removes the need for a particular stacking clip for conventional photovoltaic modules with aluminum profiled frames. Further, the peripheral component or frame may have holes in the predetermined location to facilitate easy installation of the module.
如前所述，本發明之實施例於光伏打安裝中亦提供互聯相鄰之光伏打模組在一起之手段，舉例來說，包含：As described above, embodiments of the present invention also provide means for interconnecting adjacent photovoltaic modules in a photovoltaic installation, for example, including:
‧於頂部外圍組件311中雙端主動公連接器322夾至主動母連接器320，以在光伏打系統中提供相鄰之光伏打模組之間的電性及機械性互聯。The double-ended active male connector 322 is clamped to the active female connector 320 in the top peripheral component 311 to provide electrical and mechanical interconnection between adjacent photovoltaic modules in the photovoltaic system.
‧於底部外圍組件313中雙端被動公連接器322夾至被動母連接器320，以在光伏打系統中提供相鄰之光伏打模組之間的機械性互聯；以及The double-ended passive male connector 322 is clamped to the passive female connector 320 in the bottom peripheral component 313 to provide a mechanical interconnection between adjacent photovoltaic modules in the photovoltaic system;
‧於頂部外圍組件311中單端主動公連接器323夾至主動母連接器，以提供自光伏打模組至電纜324之連接而用於接下來連接至換流器。• The single-ended active male connector 323 is clamped to the active female connector in the top peripheral component 311 to provide a connection from the photovoltaic module to the cable 324 for subsequent connection to the inverter.
所屬技術領域者將了解的是在不脫離大致地說明之本發明之範疇下，可對如特定實施例所示之本發明進行多種變化及/或修改。因此本實施例在各方面係視為說明性而非限制性。
