下面將詳細地說明本新型的較佳實施例,舉凡本中所述的元件、元件子部、結構、材料、配置等皆可不依說明的順序或所屬的實施例而任意搭配成新的實施例,此些實施例當屬本新型之範疇。 The preferred embodiments of the present invention will be described in detail below, and the components, component parts, structures, materials, configurations, and the like described herein may be arbitrarily combined into new embodiments without the order of the description or the embodiments. These embodiments are within the scope of the present invention.
本新型的實施例及圖示眾多,為了避免混淆,類似的元件係以相同或相似的標號示之;為避免畫面過度複雜及混亂,重覆的元件僅標示一處,他處則以此類推。 In order to avoid confusion, similar elements are denoted by the same or similar reference numerals; in order to avoid excessive complexity and confusion of the picture, repeated elements are only marked with one place, and so on. .
現參考圖1-3及圖4,其分別顯示根據本新型一實施例之可撓式太陽能板模組1000的製造方法及圖3之可撓式太陽能板模組1000的概略橫剖面圖。首先,如圖1所示,準備複數片不可撓之太陽能板100與100’(圖1中只顯示三片作為示意,可準備更多片)以及複數片比不可撓之太陽能板100與100’略大的不可撓之蓋板如玻璃蓋板130。如圖4所示,每一不可撓之太陽能板100與100’由下至上具有由背玻璃102與光電元件層101所構成的疊層結構。光電 元件層101由下而上可包含下電極層、光電轉換層、選擇性緩衝層及透明上電極層如氧化銦錫(ITO)及/或氧化鋅層(ZnO)。下電極與透明上電極層係用以傳輸由光電轉換層所產生的電流。光電轉換層係用以吸收穿透過透明上電極層與選擇性緩衝層的光並將其轉換為電流,其可包含由銅(Cu)、銦(In)、鎵(Ga)與硒(Se)所構成的半導體材料,或可包含由Ib族元素如銅(Cu)或銀(Ag)、IIIb族元素如鋁(Al)、鎵(Ga)或銦(In)與VIb元素如硫(S)、硒(Se)或碲(Te)所構成的化合物半導體材料。選擇性緩衝層係用以在形成透明上電極層時保護光電轉換層並協助電傳輸。不可撓之太陽能板100與100’之結構相同,其相異之處在於配置的位向左右相反,因此後續僅說明其中一者作為代表。每一不可撓之太陽能板100(100’)尚包含設置在兩側電極處的正面正極配線121b(121b’)、正面負極配線111a(111a’)、由正面正極配線121b(121b’)反折至不可撓之太陽能板100(100’)之背面的背面正極配線122b(122b’)及由正面負極配線111a(111a’)反折至不可撓之太陽能板100(100’)之背面的背面負極配線112a(112a’)。在本新型之所有圖示中,背面正極配線122b(122b’)與背面負極配線112a(112a’)係以虛線呈現,以與正面配線有所區別。又,應注意,在圖4及本案之所有圖示中,元件並未依比例繪製;例如,正面正極配線121b(121b’)與正面負極配線111a(111a’)的寬度應遠小於光電元件層101與背玻璃102的寬度,然為了清楚呈現配線與其他元件之間的電連接關係,在圖中特別將其放大。又,在實際之一橫剖面中應無法同時見到正極配線121b(121b’)、正面負極配線111a(111a’)與背面正極配線122b(122b’)、背面負極配線112a(112a’)實體相連,但圖4 為了表達上述者的電連接關係,特以實體相連方式呈現之。再者,概圖4之目的在於呈現不同元件之間的相對關係,並未顯示出每一元件之細部結構;例如,光電元件層101應包含圖案化的下電極層、圖案化的光電轉換層、圖案化的選擇性緩衝層及圖案化的透明上電極層,但為了避免圖示過於複雜模糊焦點,僅以未圖案化的單層結構來表示光電元件層101。正面正極配線121b(121b’)係與不可撓之太陽能板100(100’)的正極電連接,正面負極配線111a(111a’)係與不可撓之太陽能板100(100’)的負極電連接。配線例如可由銅箔(Copper foil)或銅帶(Copper ribbon)構成,亦可由其他金屬或合金線材構成。每一不可撓之太陽能板100(100’)可包含至少一個太陽能單位元件(unit cell),或者可包含多個彼此串聯的太陽能單位元件。不可撓之蓋板如玻璃蓋板130為不可撓之結構,厚度應儘可能地薄。 Referring now to Figures 1-3 and 4, there are shown schematic cross-sectional views of a method of fabricating a flexible solar panel module 1000 and a flexible solar panel module 1000 of Figure 3, respectively, in accordance with an embodiment of the present invention. First, as shown in FIG. 1, a plurality of inflexible solar panels 100 and 100' are prepared (only three sheets are shown in FIG. 1 as illustrations, more sheets can be prepared) and a plurality of sheets are less than inflexible solar panels 100 and 100'. A slightly larger inflexible cover such as a glass cover 130. As shown in Fig. 4, each of the inflexible solar panels 100 and 100' has a laminated structure composed of a back glass 102 and a photovoltaic element layer 101 from bottom to top. photoelectric The element layer 101 may include a lower electrode layer, a photoelectric conversion layer, a selective buffer layer, and a transparent upper electrode layer such as indium tin oxide (ITO) and/or a zinc oxide layer (ZnO) from bottom to top. The lower electrode and the transparent upper electrode layer are used to transmit the current generated by the photoelectric conversion layer. The photoelectric conversion layer is configured to absorb light passing through the transparent upper electrode layer and the selective buffer layer and convert it into a current, which may include copper (Cu), indium (In), gallium (Ga), and selenium (Se). The semiconductor material may be composed of a group Ib element such as copper (Cu) or silver (Ag), a group IIIb element such as aluminum (Al), gallium (Ga) or indium (In) and a VIb element such as sulfur (S). A compound semiconductor material composed of selenium (Se) or tellurium (Te). The selective buffer layer is used to protect the photoelectric conversion layer and assist in electrical transmission when the transparent upper electrode layer is formed. The inflexible solar panels 100 have the same structure as the 100', except that the positions of the arrangement are opposite to the left and right, so only one of them will be described as a representative. Each inflexible solar panel 100 (100') further includes a front positive wiring 121b (121b') disposed at both side electrodes, a front negative wiring 111a (111a'), and a front positive wiring 121b (121b') The back positive electrode wiring 122b (122b') on the back surface of the inflexible solar panel 100 (100') and the back surface negative electrode which is folded back from the front negative electrode wiring 111a (111a') to the back surface of the inflexible solar panel 100 (100') Wiring 112a (112a'). In all of the drawings of the present invention, the back positive electrode wiring 122b (122b') and the back surface negative wiring 112a (112a') are shown by broken lines to be distinguished from the front wiring. Further, it should be noted that in all of the drawings in FIG. 4 and the present disclosure, elements are not drawn to scale; for example, the widths of the front positive wiring 121b (121b') and the front negative wiring 111a (111a') should be much smaller than the photovoltaic element layer. The width of the 101 and back glass 102, in order to clearly show the electrical connection between the wiring and other components, is particularly magnified in the figure. Further, in one of the actual cross sections, the positive electrode wiring 121b (121b'), the front negative electrode wiring 111a (111a'), the back positive electrode wiring 122b (122b'), and the rear negative wiring 112a (112a') should not be physically connected. But Figure 4 In order to express the electrical connection relationship of the above, it is presented in a physical connection manner. Moreover, the purpose of the overview 4 is to present the relative relationship between the different elements, and does not show the detailed structure of each element; for example, the photovoltaic element layer 101 should include a patterned lower electrode layer, a patterned photoelectric conversion layer. The patterned selective buffer layer and the patterned transparent upper electrode layer are used to indicate the photovoltaic element layer 101 only in an unpatterned single layer structure in order to avoid excessively complicated blurring of the focus. The front positive electrode wiring 121b (121b') is electrically connected to the positive electrode of the inflexible solar panel 100 (100'), and the front negative wiring 111a (111a') is electrically connected to the negative electrode of the inflexible solar panel 100 (100'). The wiring may be composed of, for example, a copper foil or a copper ribbon, or may be composed of other metal or alloy wires. Each inflexible solar panel 100 (100') may comprise at least one solar unit cell or may comprise a plurality of solar unit elements in series with one another. The inflexible cover, such as the cover glass 130, is an inflexible structure and should be as thin as possible.

A second waterproof rubber material such as butyl rubber 161 is disposed between the glass cover plate 130 and the flexible back plate 140 to protect the solar panel 100' (100) and its wiring from moisture and mechanical force. At the same time, the flexibility between the invisible cover plate and the glass cover plate 130 is taken into consideration, wherein the first waterproof rubber material 160 and the second waterproof rubber material 161 may be the same waterproof rubber material or different waterproof rubber materials. Another waterproof material such as a material similar to the flexible back sheet or a waterproof adhesive material such as thermoplastic polyolefin 170 may be selectively disposed on the exposed portions 151 and 152 of the flexible back sheet 140 to protect the wiring. 151 and 152 are not affected by moisture and mechanical force, while taking into account the flexibility of the flexible backing plate 140.
在上述圖1-3與4的實施例中,由於可撓式背板140具有可撓性,故只要相鄰不可撓之太陽能板100’(100)之間具有充分間隙,便可成就具有複數可折區(圖1-3中由距離d所表示之區域)的可撓式 太陽能板模組1000。在一較佳實施例中,不可撓之太陽能板100’(100)之間的間隙距離係不小於不可撓之太陽能板100(100')與不可撓之蓋板如玻璃蓋板130(130')的厚度總和。除此之外,當不可撓之太陽能板100(100’)的背玻璃102及不可撓之蓋板如玻璃蓋板130皆足夠薄如皆小於或等於2.0mm時,不可撓之太陽能板100(100’)將變得可輕微彎曲(bendable),進一步優化可撓式太陽能板模組1000的可撓性。又,在上述圖1-3與4的實施例中,可撓式太陽能板模組1000中的各個不可撓之太陽能板100’(100)係以並聯方式相互電連接,但應瞭解,本新型亦可應用至以串聯方式電連接的太陽能板。 In the above embodiments of FIGS. 1-3 and 4, since the flexible back plate 140 has flexibility, as long as there is sufficient gap between the adjacent inflexible solar panels 100' (100), it is possible to achieve a plurality of Flexible in the foldable area (the area indicated by the distance d in Figures 1-3) Solar panel module 1000. In a preferred embodiment, the gap distance between the inflexible solar panels 100' (100) is not less than the inflexible solar panel 100 (100') and the inflexible cover such as the glass cover 130 (130' The sum of the thicknesses. In addition, when the back glass 102 of the inflexible solar panel 100 (100') and the inflexible cover such as the glass cover 130 are sufficiently thin, such as less than or equal to 2.0 mm, the inflexible solar panel 100 ( 100') will become bendable, further optimizing the flexibility of the flexible solar panel module 1000. Moreover, in the above embodiments of FIGS. 1-3 and 4, each of the inflexible solar panels 100' (100) in the flexible solar panel module 1000 is electrically connected to each other in parallel, but it should be understood that the present invention It can also be applied to solar panels that are electrically connected in series.
現參考圖4A,其顯示根據本新型之可撓式太陽能板模組1000的局部放大圖,強調可撓式背板140的撓曲狀態暨模組1000中的膠材分佈,故省略正面與背面的所有配線。如圖4A中所示,當相鄰之不可撓之蓋板如玻璃蓋板130之間具有充分的間隙時,可撓式背板140在相鄰之不可撓之蓋板如玻璃蓋板130之間處於可撓狀態,由於真空吸附作用,可撓性基板140在不可撓之蓋板如玻璃蓋板130邊緣處會較靠近不可撓之蓋板如玻璃蓋板130,但受限於不可撓之蓋板如玻璃蓋板130、光電元件層101與背玻璃102的厚度,可撓性基板140在不可撓之蓋板如玻璃蓋板130的中央處會最遠離不可撓之蓋板如玻璃蓋板130。因此在實際應用中,除了圖4所示之兩相鄰不可撓之蓋板如玻璃蓋板130之間的第一防水膠材160外,亦在不可撓之蓋板如玻璃蓋板130與可撓式背板140之間設置第二防水膠材161包覆對應之該不可撓之太陽能板的一側邊(如圖4A所示)。第二防水膠材161包含與第一防水膠材160相同的材料如 熱塑性聚烯烴(thermalplastic polyolefin,TPO),或與第一防水膠材160相異的材料如丁基膠(butyl rubber)。又,圖4A之元件標號162代表可撓式背板140與太陽能板100或100’(包含背玻璃102與光電元件層101)之背面之間的第一封裝材,圖4A之元件標號103代表不可撓之蓋板如玻璃蓋板130與太陽能板100或100’之正面之間的第二封裝材。由於太陽能板100或100’四面八方皆受到封裝材(第一與第二封裝材)及/或防水膠材(160與161)之包覆,能避免太陽能板100或100’中的光電元件層101受到水氣影響而質變退化,亦能固著太陽能板而省略傳統太陽能板模組所需的邊框。 Referring now to Figure 4A, there is shown a partial enlarged view of a flexible solar panel module 1000 in accordance with the present invention, emphasizing the flexural state of the flexible back panel 140 and the distribution of the glue in the module 1000, so that the front and back are omitted. All wiring. As shown in FIG. 4A, when there is sufficient gap between adjacent inflexible covers such as the cover glass 130, the flexible back plate 140 is adjacent to the inflexible cover such as the cover glass 130. The flexible substrate 140 is closer to the inflexible cover such as the cover glass 130 at the edge of the inflexible cover such as the cover glass 130 due to the vacuum adsorption, but is limited by the inflexible The thickness of the cover plate such as the cover glass 130, the photoelectric element layer 101 and the back glass 102, the flexible substrate 140 is farthest from the invisible cover such as the glass cover at the center of the inflexible cover such as the cover glass 130. 130. Therefore, in practical applications, in addition to the two adjacent inflexible cover plates shown in FIG. 4, such as the first waterproof rubber material 160 between the glass cover plates 130, the invisible cover plate such as the glass cover plate 130 and the A second waterproof rubber 161 is disposed between the flexible back plates 140 to cover one side of the inflexible solar panel (as shown in FIG. 4A). The second waterproof rubber 161 includes the same material as the first waterproof rubber 160, such as A thermoplastic polyolefin (TPO), or a material different from the first waterproof rubber 160, such as a butyl rubber. Moreover, the reference numeral 162 of FIG. 4A represents the first package between the flexible back plate 140 and the back surface of the solar panel 100 or 100' (including the back glass 102 and the photovoltaic element layer 101), and the component number 103 of FIG. 4A represents An inflexible cover such as a second encapsulant between the cover glass 130 and the front side of the solar panel 100 or 100'. Since the solar panel 100 or 100' is covered by the encapsulating material (the first and second encapsulating materials) and/or the waterproof rubber (160 and 161) in all directions, the photovoltaic element layer 101 in the solar panel 100 or 100' can be avoided. Due to the influence of moisture, the quality is degraded, and the solar panels can be fixed to omit the frame required for the conventional solar panel module.

The flexible solar panel module 1000 of the present invention can be mass-produced by paralleling the plurality of solar panels 100 and 100' and can be adapted to various terrains by virtue of its flexibility, and thus can be permanently fixed to the installation. In view of the above situation considerations, fixed fixation and waterproofness should be strengthened. To achieve this, the first waterproof rubber 160 (or the third waterproof rubber material having the same or different materials) may be disposed between the inner edge of the fixing hole and the fixing member 210 to minimize the gap between the fixing member 210 and the fixing hole. Clearance, and additionally set the first waterproof rubber 160 (or the third waterproof rubber with the same material or different materials) to be flexible The back surface of the back plate 140 surrounds the fixing hole to prevent moisture from penetrating from the fixing hole. In order to further increase the water repellency, the selective waterproof cushions 181 and 182 may be respectively disposed above the fixing hole and below the fixing hole to cover the upper side of the fixing hole.
為了增加固定的強度及範圍,可在可撓式背板140上加裝選擇性的下壓件200。可調整下壓件200的左右延伸寬度,使其能夠覆於玻璃蓋板130之上(如圖6所示),或使其只局限於太陽能板100與100’之間。亦可調整下壓件200的延伸長度,使其長度超過可撓式太陽能板模組1000的寬度(如圖5所示)’或使其長度遠小於可撓式太陽能板模組1000的寬度而以島狀方式分佈於太陽能板模組1000中。防水緩衝墊片181的形狀與尺寸可與下壓件200相同或相異,例如可延伸至玻璃蓋板130上、延伸包覆太陽能板100/100’的側壁或介於相鄰的太陽能板100與100’之間。固定件210例如可以是螺絲、鉚釘、扣件等。視下壓件200的延伸長度而定,一下壓件200可具有複數個孔洞以搭配複數個固定件210(如圖5所示),或一下壓件200僅具有一個孔洞以搭配單一個固定件210。若欲永久固定可撓式太陽能板模組1000不再拆卸,則在固定前可選擇性地在固定面(如屋頂板500之正面或例如地面)上鋪設熱塑材料,然後再鋪設本新型之可撓式太陽能板模組1000,將可撓式太陽能板模組1000直接熱塑固著於固定面上。 To increase the strength and extent of attachment, a selective lowering member 200 can be added to the flexible backing plate 140. The left and right extension width of the lower pressing member 200 can be adjusted to cover the glass cover 130 (as shown in Fig. 6) or to be limited to only between the solar panels 100 and 100'. The extension length of the pressing member 200 can also be adjusted to exceed the width of the flexible solar panel module 1000 (as shown in FIG. 5) or to be much shorter than the width of the flexible solar panel module 1000. It is distributed in the solar panel module 1000 in an island manner. The shape and size of the waterproof cushion 181 may be the same as or different from that of the lower pressing member 200, for example, may extend onto the glass cover plate 130, extend the side wall of the solar panel 100/100' or be adjacent to the adjacent solar panel 100. Between 100'. The fixing member 210 may be, for example, a screw, a rivet, a fastener, or the like. Depending on the extension of the lower pressing member 200, the lower pressing member 200 may have a plurality of holes to match the plurality of fixing members 210 (as shown in FIG. 5), or the lower pressing member 200 has only one hole to match the single fixing member. 210. If the permanent solar panel module 1000 is to be permanently fixed, the thermoplastic material may be selectively laid on the fixing surface (such as the front surface of the roof panel 500 or the ground, for example) before being fixed, and then the new type is laid. The flexible solar panel module 1000 directly fixes the flexible solar panel module 1000 on the fixing surface.

本新型的實施例及圖示眾多,為了避免混淆,類似的元件係以相同或相似的標號示之;為避免畫面過度複雜及混亂,重覆的元件僅標示一處,他處則以此類推。 In order to avoid confusion, similar elements are denoted by the same or similar reference numerals; in order to avoid excessive complexity and confusion of the picture, repeated elements are only marked with one place, and so on. .
現參考圖1-3及圖4,其分別顯示根據本新型一實施例之可撓式太陽能板模組1000的製造方法及圖3之可撓式太陽能板模組1000的概略橫剖面圖。首先,如圖1所示,準備複數片不可撓之太陽能板100與100’(圖1中只顯示三片作為示意,可準備更多片)以及複數片比不可撓之太陽能板100與100’略大的玻璃蓋板130。如圖4所示,每一不可撓之太陽能板100與100’由下至上具有由背玻璃102與光電元件層101所構成的疊層結構。光電元件層101由下而上可包含下電極層、光電轉換層、選擇性緩衝層及透明上電極層如氧化銦錫(ITO)及/或氧化鋅層(ZnO)。下電極與透明上電極層係用以傳輸由光電轉換層所產生的電流。光電轉換層係用以吸收穿透過透明上電極層與選擇性緩衝層的光並將其轉換為電流,其可包含由銅(Cu)、銦(In)、鎵(Ga)與硒(Se)所構成的半導體材料,或可包含由Ib族元素如銅(Cu)或銀(Ag)、IIIb族元 素如鋁(Al)、鎵(Ga)或銦(In)與VIb元素如硫(S)、硒(Se)或碲(Te)所構成的化合物半導體材料。選擇性緩衝層係用以在形成透明上電極層時保護光電轉換層並協助電傳輸。不可撓之太陽能板100與100’之結構相同,其相異之處在於配置的位向左右相反,因此後續僅說明其中一者作為代表。每一不可撓之太陽能板100(100’)尚包含設置在兩側電極處的正面正極配線121b(121b’)、正面負極配線111a(111a’)、由正面正極配線121b(121b’)反折至不可撓之太陽能板100(100’)之背面的背面正極配線122b(122b’)及由正面負極配線111a(111a’)反折至不可撓之太陽能板100(100’)之背面的背面負極配線112a(112a’)。在本新型之所有圖示中,背面正極配線122b(122b’)與背面負極配線112a(112a’)係以虛線呈現,以與正面配線有所區別。又,應注意,在圖4及本案之所有圖示中,元件並未依比例繪製;例如,正面正極配線121b(121b’)與正面負極配線111a(111a’)的寬度應遠小於光電元件層101與背玻璃102的寬度,然為了清楚呈現配線與其他元件之間的電連接關係,在圖中特別將其放大。又,在實際之一橫剖面中應無法同時見到正極配線121b(121b’)、正面負極配線111a(111a’)與背面正極配線122b(122b’)、背面負極配線112a(112a’)實體相連,但圖4為了表達上述者的電連接關係,特以實體相連方式呈現之。再者,概圖4之目的在於呈現不同元件之間的相對關係,並未顯示出每一元件之細部結構;例如,光電元件層101應包含圖案化的下電極層、圖案化的光電轉換層、圖案化的選擇性緩衝層及圖案化的透明上電極層,但為了避免圖示過於複雜模糊焦點,僅以未圖案化的單層結構來表示光電元件層101。正面正極配線121b(121b’)係 與不可撓之太陽能板100(100’)的正極電連接,正面負極配線111a(111a’)係與不可撓之太陽能板100(100’)的負極電連接。配線例如可由銅箔(Copper foil)或銅帶(Copper ribbon)構成,亦可由其他金屬或合金線材構成。每一不可撓之太陽能板100(100’)可包含至少一個太陽能單位元件(unit cell),或者可包含多個彼此串聯的太陽能單位元件。玻璃蓋板130為不可撓之結構,厚度應儘可能地薄。 Referring now to Figures 1-3 and 4, there are shown schematic cross-sectional views of a method of fabricating a flexible solar panel module 1000 and a flexible solar panel module 1000 of Figure 3, respectively, in accordance with an embodiment of the present invention. First, as shown in FIG. 1, a plurality of inflexible solar panels 100 and 100' are prepared (only three sheets are shown in FIG. 1 as illustrations, more sheets can be prepared) and a plurality of sheets are less than inflexible solar panels 100 and 100'. A slightly larger glass cover 130. As shown in Fig. 4, each of the inflexible solar panels 100 and 100' has a laminated structure composed of a back glass 102 and a photovoltaic element layer 101 from bottom to top. The photovoltaic element layer 101 may include a lower electrode layer, a photoelectric conversion layer, a selective buffer layer, and a transparent upper electrode layer such as indium tin oxide (ITO) and/or a zinc oxide layer (ZnO) from bottom to top. The lower electrode and the transparent upper electrode layer are used to transmit the current generated by the photoelectric conversion layer. The photoelectric conversion layer is configured to absorb light passing through the transparent upper electrode layer and the selective buffer layer and convert it into a current, which may include copper (Cu), indium (In), gallium (Ga), and selenium (Se). The semiconductor material is formed, or may comprise a group Ib element such as copper (Cu) or silver (Ag), group IIIb A compound semiconductor material composed of aluminum (Al), gallium (Ga) or indium (In) and a VIb element such as sulfur (S), selenium (Se) or tellurium (Te). The selective buffer layer is used to protect the photoelectric conversion layer and assist in electrical transmission when the transparent upper electrode layer is formed. The inflexible solar panels 100 have the same structure as the 100', except that the positions of the arrangement are opposite to the left and right, so only one of them will be described as a representative. Each inflexible solar panel 100 (100') further includes a front positive wiring 121b (121b') disposed at both side electrodes, a front negative wiring 111a (111a'), and a front positive wiring 121b (121b') The back positive electrode wiring 122b (122b') on the back surface of the inflexible solar panel 100 (100') and the back surface negative electrode which is folded back from the front negative electrode wiring 111a (111a') to the back surface of the inflexible solar panel 100 (100') Wiring 112a (112a'). In all of the drawings of the present invention, the back positive electrode wiring 122b (122b') and the back surface negative wiring 112a (112a') are shown by broken lines to be distinguished from the front wiring. Further, it should be noted that in all of the drawings in FIG. 4 and the present disclosure, elements are not drawn to scale; for example, the widths of the front positive wiring 121b (121b') and the front negative wiring 111a (111a') should be much smaller than the photovoltaic element layer. The width of the 101 and back glass 102, in order to clearly show the electrical connection between the wiring and other components, is particularly magnified in the figure. Further, in one of the actual cross sections, the positive electrode wiring 121b (121b'), the front negative electrode wiring 111a (111a'), the back positive electrode wiring 122b (122b'), and the rear negative wiring 112a (112a') should not be physically connected. However, in order to express the electrical connection relationship of the above, FIG. 4 is specifically presented in a physical connection manner. Moreover, the purpose of the overview 4 is to present the relative relationship between the different elements, and does not show the detailed structure of each element; for example, the photovoltaic element layer 101 should include a patterned lower electrode layer, a patterned photoelectric conversion layer. The patterned selective buffer layer and the patterned transparent upper electrode layer are used to indicate the photovoltaic element layer 101 only in an unpatterned single layer structure in order to avoid excessively complicated blurring of the focus. Front positive electrode wiring 121b (121b') The positive electrode wiring 111a (111a') is electrically connected to the negative electrode of the inflexible solar panel 100 (100'). The wiring may be composed of, for example, a copper foil or a copper ribbon, or may be composed of other metal or alloy wires. Each inflexible solar panel 100 (100') may comprise at least one solar unit cell or may comprise a plurality of solar unit elements in series with one another. The cover glass 130 is an inflexible structure and should be as thin as possible.

The first encapsulant and the second encapsulant may be the same or different, and may include a thermal encapsulant such as Ethylene Vinyl Acetate (EVA), polyolefin (PO), and polyvinyl alcohol. Polyvinyl butyral (PVB) or UV curable encapsulant. An appropriate distance should be maintained between each inflexible solar panel 100 and the adjacent inflexible solar panel 100', that is, an appropriate distance should be protected between each of the glass cover sheets 130 and the adjacent sheet glass cover 130. d. The flexible back sheet 140 may be a high tension plastic sheet such as a polyethylene (PE) sheet, a polyamide (PA) sheet, a polyethylene terephthalate (PET) sheet, or The above is a sheet of aluminum foil attached. The flexible backplane 140 has at least one aperture (not shown) at a central region corresponding to each of the inflexible solar panels 100 (100'). The back positive electrode wiring 122b (122b') and the back surface negative wiring 112a (112a') on the back surface of each of the inflexible solar panels 100 (100') are separated from the first package (not shown) by at least one hole (not The illustrations are worn out to connect outwards and connect to each other.

The back plate 140 is attached and fixed.
然後,如圖3所示並參考圖4,在可撓式背板140的末端上固定接線盒150。為了強化接線盒150處的可撓式背板140以避免其受損,可在接線盒150與可撓式背板140之間插入強化層141。強化層141的材料可與可撓式背板140相同或不同,且強化層141除了設置於接線盒150與可撓式背板140之間外,尚可選擇性地設置於可撓式背板140的外圍處。如圖4所示,使每一片不可撓之太陽能板100(100’)自可撓式背板140之孔洞(未圖示)穿出的背面正極配線122b(122b’)經由平貼於可撓式背板140背面的配線151而與相鄰之不可撓之太陽能板100’(100)的背面正極配線122b’(122b)電連接,使每一片不可撓之太陽能板100(100’)自可撓式背板140之孔洞(未圖示)穿出的背面負極配線112a(112a’)經由平貼於可撓式背板140背面的配線152而與相鄰之不可撓之太陽能板100’(100)的背面負極配線112a’(112a)電連接。最靠近接線盒150之不可撓之太陽能板100(100’)的背面正極配線122b(122b’)係經由配線151而與接線盒150的正極電連接,其背面負極配線112a(112a’)係經由配線152而與接線盒150的負極電連接。以上步驟大致上完成本新型之可撓式太陽能板模組1000之製造。配線151與152可以分別是背面正極配線122b(122b’)本身( 其延伸)與背面負極配線112a(112a’)本身(其延伸),也可以是不同的線材。接線盒150更包含正極配線151’與負極配線152’以使可撓式太陽能板模組1000對外電連接。在相鄰之玻璃蓋板130之間設置第一防水膠材如熱塑性聚烯烴(thermalplastic polyolefin,TPO)160與可撓式背板140實體接觸並在玻璃蓋板130與可撓式背板140之間設置第二防水膠材如丁基膠(butyl rubber)161,以保護太陽能板100’(100)以及其配線不受水氣、機械力的影響,同時兼顧玻璃蓋板130之間的可撓性,其中第一防水膠材160與第二防水膠材161可以為相同防水膠材或不同之防水膠材。在可撓式背板140的背面配線151與152裸露處可選擇性地設置另一層防水材如與可撓式背板相同的一材質或一防水膠材如熱塑性聚烯烴170等,以保護配線151與152不受水氣、機械力的影響,同時兼顧可撓式背板140的可撓性。 Then, as shown in FIG. 3 and with reference to FIG. 4, the junction box 150 is fixed to the end of the flexible backplane 140. To reinforce the flexible backing plate 140 at the junction box 150 to avoid damage thereto, a reinforcing layer 141 can be inserted between the junction box 150 and the flexible backing plate 140. The material of the reinforcing layer 141 may be the same as or different from the flexible backing plate 140, and the reinforcing layer 141 may be selectively disposed on the flexible backing plate except for being disposed between the junction box 150 and the flexible backing plate 140. At the periphery of 140. As shown in FIG. 4, the back positive electrode wiring 122b (122b') through which the inflexible solar panel 100 (100') is passed through the hole (not shown) of the flexible backing plate 140 is affixed to the flexible The wiring 151 on the back of the backplane 140 is electrically connected to the back positive wiring 122b' (122b) of the adjacent inflexible solar panel 100' (100), so that each inflexible solar panel 100 (100') is self-contained. The back negative electrode wiring 112a (112a') through which the hole (not shown) of the flexible back plate 140 passes is connected to the adjacent inflexible solar panel 100' via the wiring 152 that is flatly attached to the back surface of the flexible backplane 140 ( 100) The back negative wiring 112a' (112a) is electrically connected. The back positive electrode wiring 122b (122b') of the inflexible solar panel 100 (100') closest to the junction box 150 is electrically connected to the positive electrode of the junction box 150 via the wiring 151, and the back surface negative wiring 112a (112a') is via The wiring 152 is electrically connected to the negative electrode of the junction box 150. The above steps substantially complete the manufacture of the flexible solar panel module 1000 of the present invention. The wirings 151 and 152 may be the back positive wiring 122b (122b') itself ( The extension) and the back negative wiring 112a (112a') itself (the extension thereof) may be different wires. The junction box 150 further includes a positive electrode wiring 151' and a negative electrode wiring 152' to electrically connect the flexible solar panel module 1000 to the outside. A first waterproof rubber material such as a thermoplastic polyolefin (TPO) 160 is physically disposed between the adjacent glass cover plates 130 and the flexible back plate 140 is in contact with the glass cover plate 130 and the flexible back plate 140. A second waterproof rubber material such as butyl rubber 161 is disposed to protect the solar panel 100' (100) and its wiring from moisture and mechanical force, and at the same time, the flexibility between the glass cover plates 130 is considered. The first waterproof rubber material 160 and the second waterproof rubber material 161 may be the same waterproof rubber material or different waterproof rubber materials. Another waterproof material such as a material similar to the flexible back sheet or a waterproof adhesive material such as thermoplastic polyolefin 170 may be selectively disposed on the exposed portions 151 and 152 of the flexible back sheet 140 to protect the wiring. 151 and 152 are not affected by moisture and mechanical force, while taking into account the flexibility of the flexible backing plate 140.
在上述圖1-3與4的實施例中,由於可撓式背板140具有可撓性,故只要相鄰不可撓之太陽能板100’(100)之間具有充分間隙,便可成就具有複數可折區(圖1-3中由距離d所表示之區域)的可撓式太陽能板模組1000。在一較佳實施例中,不可撓之太陽能板100’(100)之間的間隙距離係不小於不可撓之太陽能板100(100')與玻璃蓋板130(130')的厚度總和。除此之外,當不可撓之太陽能板100(100’)的背玻璃102及玻璃蓋板130皆足夠薄如皆小於或等於2.0mm時,不可撓之太陽能板100(100’)將變得可輕微彎曲(bendable),進一步優化可撓式太陽能板模組1000的可撓性。又,在上述圖1-3與4的實施例中,可撓式太陽能板模組1000中的各個不可撓之太陽能板100’(100)係以並聯方式相互電連接,但應 瞭解,本新型亦可應用至以串聯方式電連接的太陽能板。 In the above embodiments of FIGS. 1-3 and 4, since the flexible back plate 140 has flexibility, as long as there is sufficient gap between the adjacent inflexible solar panels 100' (100), it is possible to achieve a plurality of A flexible solar panel module 1000 in a foldable region (the region indicated by the distance d in Figures 1-3). In a preferred embodiment, the gap distance between the inflexible solar panels 100' (100) is not less than the sum of the thicknesses of the inflexible solar panel 100 (100') and the glass cover panel 130 (130'). In addition, when the back glass 102 and the glass cover 130 of the inflexible solar panel 100 (100') are sufficiently thin, such as less than or equal to 2.0 mm, the inflexible solar panel 100 (100') will become The flexibility of the flexible solar panel module 1000 can be further optimized by being bendable. Moreover, in the above embodiments of FIGS. 1-3 and 4, each of the inflexible solar panels 100' (100) in the flexible solar panel module 1000 is electrically connected to each other in parallel, but should It is understood that the present invention can also be applied to solar panels that are electrically connected in series.
現參考圖4A,其顯示根據本新型之可撓式太陽能板模組1000的局部放大圖,強調可撓式背板140的撓曲狀態暨模組1000中的膠材分佈,故省略正面與背面的所有配線。如圖4A中所示,當相鄰之玻璃蓋板130之間具有充分的間隙時,可撓式背板140在相鄰之玻璃蓋板130之間處於可撓狀態,由於真空吸附作用,可撓性基板140在玻璃蓋板130邊緣處會較靠近玻璃蓋板130,但受限於玻璃蓋板130、光電元件層101與背玻璃102的厚度,可撓性基板140在玻璃蓋板130的中央處會最遠離玻璃蓋板130。因此在實際應用中,除了圖4所示之兩相鄰玻璃蓋板130之間的第一防水膠材160外,亦在玻璃蓋板130與可撓式背板140之間設置第二防水膠材161包覆對應之該不可撓之太陽能板的一側邊(如圖4A所示)。第二防水膠材161包含與第一防水膠材160相同的材料如熱塑性聚烯烴(thermalplastic polyolefin,TPO),或與第一防水膠材160相異的材料如丁基膠(butyl rubber)。又,圖4A之元件標號162代表可撓式背板140與太陽能板100或100’(包含背玻璃102與光電元件層101)之背面之間的第一封裝材,圖4A之元件標號103代表玻璃蓋板130與太陽能板100或100’之正面之間的第二封裝材。由於太陽能板100或100’四面八方皆受到封裝材(第一與第二封裝材)及/或防水膠材(160與161)之包覆,能避免太陽能板100或100’中的光電元件層101受到水氣影響而質變退化,亦能固著太陽能板而省略傳統太陽能板模組所需的邊框。 Referring now to Figure 4A, there is shown a partial enlarged view of a flexible solar panel module 1000 in accordance with the present invention, emphasizing the flexural state of the flexible back panel 140 and the distribution of the glue in the module 1000, so that the front and back are omitted. All wiring. As shown in FIG. 4A, when there is sufficient gap between adjacent glass cover plates 130, the flexible back plate 140 is in a flexible state between adjacent glass cover plates 130, due to vacuum adsorption. The flexible substrate 140 is closer to the glass cover 130 at the edge of the cover glass 130, but is limited by the thickness of the cover glass 130, the photovoltaic element layer 101 and the back glass 102, and the flexible substrate 140 is in the cover glass 130. The center will be farthest from the glass cover 130. Therefore, in practical applications, in addition to the first waterproof rubber 160 between the two adjacent glass cover plates 130 shown in FIG. 4, a second waterproof rubber is also disposed between the glass cover 130 and the flexible back plate 140. The material 161 covers one side of the inflexible solar panel (as shown in FIG. 4A). The second waterproof rubber 161 comprises the same material as the first waterproof rubber 160 such as a thermal plastic polyolefin (TPO), or a material different from the first waterproof rubber 160 such as a butyl rubber. Moreover, the reference numeral 162 of FIG. 4A represents the first package between the flexible back plate 140 and the back surface of the solar panel 100 or 100' (including the back glass 102 and the photovoltaic element layer 101), and the component number 103 of FIG. 4A represents A second encapsulant between the cover glass 130 and the front side of the solar panel 100 or 100'. Since the solar panel 100 or 100' is covered by the encapsulating material (the first and second encapsulating materials) and/or the waterproof rubber (160 and 161) in all directions, the photovoltaic element layer 101 in the solar panel 100 or 100' can be avoided. Due to the influence of moisture, the quality is degraded, and the solar panels can be fixed to omit the frame required for the conventional solar panel module.

The gap, and additionally, the first waterproof rubber 160 (or the third waterproof rubber material having the same or different materials) is disposed on the back surface of the flexible back plate 140 around the fixing hole to prevent water vapor from infiltrating from the fixing hole. In order to further increase the water repellency, the selective waterproof cushions 181 and 182 may be respectively disposed above the fixing hole and below the fixing hole to cover the upper side of the fixing hole.
為了增加固定的強度及範圍,可在可撓式背板140上加裝選擇性的下壓件200。可調整下壓件200的左右延伸寬度,使其能夠覆於玻璃蓋板130之上(如圖6所示),或使其只局限於太陽能板100與100’之間。亦可調整下壓件200的延伸長度,使其長度超過可撓式太陽能板模組1000的寬度(如圖5所示),或使其長度遠小於可撓式太陽能板模組1000的寬度而以島狀方式分佈於太陽能板模組1000中。防水緩衝墊片181的形狀與尺寸可與下壓件200相同或相異,例如可延伸至玻璃蓋板130上、延伸包覆太陽能板100/100’的側壁或介於相鄰的太陽能板100與100’之間。固定件210例如 可以是螺絲、鉚釘、扣件等。視下壓件200的延伸長度而定,一下壓件200可具有複數個孔洞以搭配複數個固定件210(如圖5所示),或一下壓件200僅具有一個孔洞以搭配單一個固定件210。若欲永久固定可撓式太陽能板模組1000不再拆卸,則在固定前可選擇性地在固定面(如屋頂板500之正面或例如地面)上鋪設熱塑材料,然後再鋪設本新型之可撓式太陽能板模組1000,將可撓式太陽能板模組1000直接熱塑固著於固定面上。 To increase the strength and extent of attachment, a selective lowering member 200 can be added to the flexible backing plate 140. The left and right extension width of the lower pressing member 200 can be adjusted to cover the glass cover 130 (as shown in Fig. 6) or to be limited to only between the solar panels 100 and 100'. The extension length of the pressing member 200 can also be adjusted to exceed the width of the flexible solar panel module 1000 (as shown in FIG. 5), or the length thereof is much smaller than the width of the flexible solar panel module 1000. It is distributed in the solar panel module 1000 in an island manner. The shape and size of the waterproof cushion 181 may be the same as or different from that of the lower pressing member 200, for example, may extend onto the glass cover plate 130, extend the side wall of the solar panel 100/100' or be adjacent to the adjacent solar panel 100.
