A long portion 120 a of one bus bar 120 is located above the long portion 130 a of the second bus bar 130 with an isolation structure interposed therebetween. As shown in FIG. 2, FIG. 3A and FIG. 3B, the short portion 120 b of the first bus bar 120 and the short portion 130 b of the second bus bar 130 extend, for example, along the first direction E1 and concentrate into the area S, so as to facilitate subsequent The plurality of bypass diodes 160 provided in one junction box 170 are connected as described.

在一實施例中,絕緣片140設置於第一匯流條120與第二匯流條130之間。詳細地說,絕緣片140位於設置於接線區10c中的第一匯流條120的長部120a與第二匯流條130的長部130a之間,且覆蓋部分的位於第一電池區10a的半切太陽能電池112以及部分的位於第二電池區10b的半切太陽能電池112。在本實施例中,絕緣片140是用來避免彼此部分重疊的第一匯流條120與第二匯流條130因接觸而短路。絕緣片140例如包括兩條第一出線口142,以使兩個第二匯流條130可各自藉由兩條第一出線口142從絕緣片140的一表面延伸至絕緣片140的另一表面。詳細地說,如上所述,兩個第二匯流條130的長部130a的部分被絕緣片140所覆蓋,為了使第二匯流條130的短部130b與第一匯流條120的短部120b藉由旁路二極體160連接,第二匯流條130的一部分長部130a會穿出第一出線口142,以使連接於所述長部130a的短部130b與第一匯流條120的短部120b在同一平面上。In one embodiment, the insulating sheet 140 is disposed between the first bus bar 120 and the second bus bar 130. In detail, the insulating sheet 140 is located between the long portion 120a of the first bus bar 120 and the long portion 130a of the second bus bar 130 provided in the wiring area 10c, and the covering portion of the half-cut solar energy located in the first battery area 10a The battery 112 and a part of the half-cut solar cell 112 located in the second battery area 10b. In this embodiment, the insulating sheet 140 is used to prevent the first bus bar 120 and the second bus bar 130 that are partially overlapping each other from being short-circuited due to contact. The insulating sheet 140 includes, for example, two first outlets 142 so that the two second bus bars 130 can each extend from one surface of the insulating sheet 140 to the other of the insulating sheet 140 through the two first outlets 142. surface. In detail, as described above, the portions of the long portions 130 a of the two second bus bars 130 are covered by the insulating sheet 140. In order to borrow the short portions 130 b of the second bus bar 130 and the short portions 120 b of the first bus bar 120, Connected by the bypass diode 160, a portion of the long portion 130a of the second bus bar 130 will pass through the first outlet 142, so that the short portion 130b connected to the long portion 130a and the short portion of the first bus bar 120 are short. The portions 120b are on the same plane.

請同時參照圖1A、圖3A及圖3B,在本實施例中,絕緣片140包括面向第一電池區10a的第一凹槽140a。由於絕緣片140包括兩條第一出線口142,位於第一出線口142之間的部分絕緣片140可能於設置時覆蓋部分半切太陽能電池112的受光面110a。為避免發生上述問題,需將位於第一出線口142之間的部分絕緣片140移除,以形成第一凹槽140a。形成的第一凹槽140a例如位於兩條第一出線口142之間。第一凹槽140a的截面例如是矩形,但本發明不以此為限。Please refer to FIGS. 1A, 3A, and 3B at the same time. In this embodiment, the insulating sheet 140 includes a first groove 140 a facing the first battery region 10 a. Since the insulating sheet 140 includes two first outlets 142, a part of the insulating sheet 140 located between the first outlets 142 may cover a part of the light receiving surface 110a of the half-cut solar cell 112 during installation. In order to avoid the above problems, a part of the insulating sheet 140 located between the first outlets 142 needs to be removed to form a first groove 140a. The first groove 140 a is formed between the two first outlets 142, for example. The cross section of the first groove 140a is, for example, rectangular, but the invention is not limited thereto.

第一凹槽140a在第一方向E1上的寬度W1例如介於焊線150在第一方向E1上至半切太陽能電池112的邊緣的距離D11與焊線150在第一方向E1上至第一匯流條120的距離D22之間。簡要地說,D11<W1<D22。由於半切太陽能電池112包括在第一方向E1上彼此相對的切割側112S1與非切割側112S2,上述提到的在第一方向E1上的半切太陽能電池112的邊緣例如可指代為非切割側112S2或者切割側112S1。為避免位於第一出線口142之間的部分絕緣片140覆蓋半切太陽能電池112的受光面或使焊線150因與絕緣片140接觸而損壞,第一凹槽140a在第一方向E1上的寬度W1需至少大於焊線150在第一方向E1上至半切太陽能電池112的邊緣的距離D11。然而,若第一凹槽140a在第一方向E1上的寬度W1過大,則將使得部分的第二匯流條130的長部130a被暴露出並與第一匯流條120的長部120a接觸而造成短路。為避免上述問題發生,第一凹槽140a在第一方向E1上的寬度W1需小於焊線150在第一方向E1上至第一匯流條120的距離D22,以防止第二匯流條130的長部130a被暴露出。寬度W1在上述範圍內可確保絕緣片140不會覆蓋半切太陽能電池112的受光面110a或者損壞焊線150,且可避免第一匯流條120與第二匯流條130發生短路的問題。在一實施例中,第一凹槽140a在第一方向E1上的寬度W1為4mm~9mm。The width W1 of the first groove 140a in the first direction E1 is, for example, a distance D11 between the bonding wire 150 in the first direction E1 and the edge of the half-cut solar cell 112 and the bonding wire 150 in the first direction E1 to the first confluence. The distance D22 between the bars 120. Briefly, D11 <W1 <D22. Since the half-cut solar cell 112 includes a cutting side 112S1 and a non-cut side 112S2 opposite to each other in the first direction E1, the edge of the half-cut solar cell 112 in the first direction E1 mentioned above may be referred to as the non-cut side 112S2 or Cut side 112S1. In order to prevent part of the insulating sheet 140 located between the first outlets 142 from covering the light-receiving surface of the half-cut solar cell 112 or causing the bonding wire 150 to be damaged due to contact with the insulating sheet 140, the first groove 140a in the first direction E1 The width W1 needs to be at least greater than the distance D11 from the bonding wire 150 in the first direction E1 to the edge of the half-cut solar cell 112. However, if the width W1 of the first groove 140a in the first direction E1 is too large, part of the long portion 130a of the second bus bar 130 is exposed and brought into contact with the long portion 120a of the first bus bar 120. Short circuit. To avoid the above problems, the width W1 of the first groove 140a in the first direction E1 must be smaller than the distance D22 from the bonding wire 150 in the first direction E1 to the first bus bar 120 to prevent the length of the second bus bar 130. The portion 130a is exposed. The width W1 within the above range can ensure that the insulating sheet 140 does not cover the light receiving surface 110a of the half-cut solar cell 112 or damage the bonding wire 150, and avoids the short circuit between the first bus bar 120 and the second bus bar 130. In one embodiment, the width W1 of the first groove 140a in the first direction E1 is 4 mm to 9 mm.

第一凹槽140a在第二方向E2上的寬度W2例如大於兩個第二匯流條130的短部130b間的距離D33加上短部130b的寬度W11。簡要地說,D33+2*W11<W2。在本實施例中,由於第二匯流條130的一部分長部130a會穿出第一出線口142,以使連接於所述長部130a的短部130b與第一匯流條120的短部120b在同一平面上,為避免第一凹槽140a在第二方向E2上的寬度W2過小而使得第二匯流條130的短部130b仍被絕緣片140所覆蓋,因此第一凹槽140a在第二方向E2上的寬度W2需至少大於兩個第二匯流條130的短部130a間的距離D33加上兩個短部130a的寬度W11的值。寬度W2在上述範圍內可確保絕緣片140不會覆蓋第二匯流條130的短部130b,以使第二匯流條130的短部130b可穿出接線口102以與位於一個接線盒170中的旁路二極體160連接。在一實施例中,第一凹槽140a在第二方向E2上的寬度W2為25mm~35mm。The width W2 of the first groove 140a in the second direction E2 is, for example, greater than the distance D33 between the short portions 130b of the two second bus bars 130 plus the width W11 of the short portions 130b. Briefly, D33 + 2 * W11 <W2. In this embodiment, a part of the long portion 130a of the second bus bar 130 passes through the first outlet 142, so that the short portion 130b connected to the long portion 130a and the short portion 120b of the first bus bar 120 On the same plane, in order to avoid that the width W2 of the first groove 140a in the second direction E2 is too small so that the short portion 130b of the second bus bar 130 is still covered by the insulating sheet 140, the first groove 140a is The width W2 in the direction E2 needs to be at least greater than the distance D33 between the short portions 130a of the two second bus bars 130 plus the width W11 of the two short portions 130a. The width W2 is within the above range to ensure that the insulating sheet 140 does not cover the short portion 130b of the second bus bar 130, so that the short portion 130b of the second bus bar 130 can pass through the connection port 102 to communicate with The bypass diode 160 is connected. In one embodiment, the width W2 of the first groove 140a in the second direction E2 is 25 mm to 35 mm.

在另一實施例中,絕緣片140可更包括面向第一電池區10a的兩個第二凹槽140b。兩個第二凹槽140b例如位於絕緣片140的角落處。兩個第二凹槽140b的形成理由與第一凹槽140a類似,絕緣片140的角落部可能於設置時覆蓋半切太陽能電池112的受光面110a或者因與位於半切太陽能電池112的背光面110b上的焊線150接觸而使其損壞。為避免發生上述問題,需對絕緣片140的角落作出特別的設計。在本實施例中,可於面向第一電池區10a的絕緣片140的角落處形成第二凹槽140b。第二凹槽140b的截面例如是三角形或矩形。以下將介紹第二凹槽140b的截面各自為三角形與矩形的情形。In another embodiment, the insulating sheet 140 may further include two second grooves 140b facing the first battery region 10a. The two second grooves 140 b are located at, for example, corners of the insulating sheet 140. The reason for forming the two second grooves 140b is similar to that of the first groove 140a. The corner portion of the insulating sheet 140 may cover the light receiving surface 110a of the half-cut solar cell 112 or be located on the backlight surface 110b of the half-cut solar cell 112 during installation. The bonding wire 150 is in contact with it and damaged. In order to avoid the above-mentioned problems, a corner of the insulating sheet 140 needs to be specially designed. In this embodiment, a second groove 140b may be formed at a corner of the insulating sheet 140 facing the first battery region 10a. The cross section of the second groove 140b is, for example, a triangle or a rectangle. The case where the cross sections of the second grooves 140b are triangular and rectangular are described below.

在一實施例中,第二凹槽140b的截面為三角形。第二凹槽140b在第一方向E1上的寬度W3介於位於第一電池區10a的半切太陽能電池112在第一方向E1上被絕緣片140覆蓋的寬度W22與第二匯流條130至位於第一電池區10a的絕緣片140的一側邊140S1的距離D44之間。簡要地說,W22<W3<D44。為避免絕緣片140的角落部覆蓋半切太陽能電池112的受光面,第二凹槽140b在第一方向E1上的寬度W3需至少大於絕緣片140在第一方向E1上覆蓋半切太陽能電池112的寬度W22。然而,若第二凹槽140b在第一方向E1上的寬度W3過大,則將使得部分的第二匯流條130的長部130a被暴露出並與第一匯流條120的長部120a接觸而造成短路。為避免上述問題發生,第二凹槽140b在第一方向E1上的寬度W3需小於第二匯流條130與位於第一電池區10a的絕緣片140的一側邊140S1之間的距離D44,以防止第二匯流條130的長部130a被暴露出。寬度W3在上述範圍內可確保絕緣片140不會覆蓋半切太陽能電池112的受光面且可避免第一匯流條120與第二匯流條130發生短路的問題。在一實施例中,第二凹槽140b在第一方向E1上的寬度W3為2mm~7mm。In one embodiment, the cross-section of the second groove 140b is triangular. The width W3 of the second groove 140b in the first direction E1 is between the width W22 of the half-cut solar cell 112 located in the first battery region 10a and the second bus bar 130 covered by the insulating sheet 140 in the first direction E1. A distance D44 between one side 140S1 of the insulating sheet 140 of a battery region 10a. Briefly, W22 <W3 <D44. In order to prevent the corners of the insulating sheet 140 from covering the light-receiving surface of the half-cut solar cell 112, the width W3 of the second groove 140b in the first direction E1 must be at least larger than the width of the insulating sheet 140 covering the half-cut solar cell 112 in the first direction E1. W22. However, if the width W3 of the second groove 140b in the first direction E1 is too large, part of the long portion 130a of the second bus bar 130 is exposed and brought into contact with the long portion 120a of the first bus bar 120. Short circuit. To avoid the above problems, the width W3 of the second groove 140b in the first direction E1 should be smaller than the distance D44 between the second bus bar 130 and one side 140S1 of the insulating sheet 140 located in the first battery area 10a. The long portion 130a of the second bus bar 130 is prevented from being exposed. The width W3 within the above range can ensure that the insulating sheet 140 does not cover the light-receiving surface of the half-cut solar cell 112 and avoid the short circuit between the first bus bar 120 and the second bus bar 130. In one embodiment, the width W3 of the second groove 140b in the first direction E1 is 2 mm to 7 mm.

第二凹槽140b在第二方向E2上的寬度W4小於第二匯流條130在第二方向E2上至絕緣片140的一側邊140S2的距離D55之間。簡要地說,W4<D55。在一實施例中,絕緣片140的側邊140S2例如與絕緣片140的側邊140S1連接,且絕緣片140的側邊140S2的延伸方向例如與絕緣片140的側邊140S1的延伸方向正交。若第二凹槽140b在第二方向E2上的寬度W4過大,則將使得部分的第二匯流條130的長部130a被暴露出並與第一匯流條120的長部120a接觸而造成短路。為避免上述問題發生,第二凹槽140b在第二方向E2上的寬度W4需小於第二匯流條130在第二方向E2上至絕緣片140的一側邊140S2的距離D55,以防止第二匯流條130的長部130a被暴露出。此外,為避免絕緣片140的角落部覆蓋半切太陽能電池112的受光面,第二凹槽140b在第二方向E2上的寬度W4也需至少大於一距離使得絕緣片140的角落部與所述半切太陽能電池112保持間距。寬度W4在上述範圍內可確保絕緣片140不會覆蓋半切太陽能電池112的受光面且可避免第一匯流條120與第二匯流條130發生短路的問題。在一實施例中,第二凹槽140b在第二方向E2上的寬度W4為5mm~10mm。A width W4 of the second groove 140b in the second direction E2 is smaller than a distance D55 between the second bus bar 130 in the second direction E2 and a side 140S2 of the insulating sheet 140. Briefly, W4 <D55. In an embodiment, the side edge 140S2 of the insulating sheet 140 is connected to the side edge 140S1 of the insulating sheet 140, and the extending direction of the side edge 140S2 of the insulating sheet 140 is orthogonal to the extending direction of the side edge 140S1 of the insulating sheet 140, for example. If the width W4 of the second groove 140b in the second direction E2 is too large, a portion of the long portion 130a of the second bus bar 130 is exposed and contacts the long portion 120a of the first bus bar 120, causing a short circuit. To avoid the above problems, the width W4 of the second groove 140b in the second direction E2 should be smaller than the distance D55 from the second bus bar 130 in the second direction E2 to the side 140S2 of the insulating sheet 140 to prevent the second The long portion 130a of the bus bar 130 is exposed. In addition, in order to prevent the corner portion of the insulating sheet 140 from covering the light-receiving surface of the half-cut solar cell 112, the width W4 of the second groove 140b in the second direction E2 must also be at least greater than a distance such that the corner portion of the insulating sheet 140 and the half-cut The solar cells 112 maintain a pitch. The width W4 within the above range can ensure that the insulating sheet 140 does not cover the light-receiving surface of the half-cut solar cell 112 and avoid the short circuit between the first bus bar 120 and the second bus bar 130. In one embodiment, the width W4 of the second groove 140b in the second direction E2 is 5 mm to 10 mm.

在另一實施例中,第二凹槽140b的截面為矩形。第二凹槽140b在第一方向E1上的寬度W5介於位於第一電池區10a的半切太陽能電池112在第一方向E1上被絕緣片140覆蓋的寬度W22與焊線150至在第一方向E1上至半切太陽能電池112的邊緣的距離D11之間。簡要地說,W22<W5<D11。為避免絕緣片140的角落部覆蓋半切太陽能電池112的受光面,第二凹槽140b在第一方向E1上的寬度W5需至少大於絕緣片140在第一方向E1上覆蓋半切太陽能電池112的寬度W22。然而,若第二凹槽140b在第一方向E1上的寬度W5過大,則將使得於設置絕緣片140時,部分的位於半切太陽能電池112的背光面的焊線150因與絕緣片140接觸而損壞。為避免上述問題發生,第二凹槽140b在第一方向E1上的寬度W5需小於焊線150在第一方向E1上至半切太陽能電池112的邊緣的距離D11,以防止部分的位於半切太陽能電池112的背光面的焊線150與絕緣片140接觸。寬度W5在上述範圍內可確保絕緣片140不會覆蓋半切太陽能電池112的受光面110a且可避免焊線150損壞的問題。在一實施例中,第二凹槽140b在第一方向E1上的寬度W5為2mm~4mm。此外,由於寬度W5在上述範圍內,因此本實施例的絕緣片140具有對位的功能。詳細地說,在設置絕緣片140時,當具有第二凹槽140b的絕緣片140的角落部與半切太陽能電池112的邊緣接觸時,則可確定絕緣片140已經對位設置,且絕緣片140不會覆蓋半切太陽能電池112的受光面110a也不會接觸焊線150。In another embodiment, the cross-section of the second groove 140b is rectangular. The width W5 of the second groove 140b in the first direction E1 is between the width W22 of the half-cut solar cell 112 located in the first battery area 10a and the bonding wire 150 covered by the insulating sheet 140 in the first direction E1 to the first direction. The distance D1 from the top of E1 to the edge of the half-cut solar cell 112. Briefly, W22 <W5 <D11. To prevent the corners of the insulating sheet 140 from covering the light-receiving surface of the half-cut solar cell 112, the width W5 of the second groove 140b in the first direction E1 must be at least larger than the width of the insulating sheet 140 covering the half-cut solar cell 112 in the first direction E1. W22. However, if the width W5 of the second groove 140b in the first direction E1 is too large, when the insulating sheet 140 is provided, a part of the bonding wire 150 located on the backlight surface of the half-cut solar cell 112 is in contact with the insulating sheet 140. damage. To avoid the above problems, the width W5 of the second groove 140b in the first direction E1 should be smaller than the distance D11 of the bonding wire 150 in the first direction E1 to the edge of the half-cut solar cell 112, so as to prevent part of the half-cut solar cell The bonding wire 150 on the backlight surface of 112 is in contact with the insulating sheet 140. The width W5 within the above range can ensure that the insulating sheet 140 does not cover the light-receiving surface 110 a of the half-cut solar cell 112 and the problem of damage to the bonding wire 150 can be avoided. In one embodiment, the width W5 of the second groove 140b in the first direction E1 is 2 mm to 4 mm. In addition, since the width W5 is within the above range, the insulating sheet 140 of this embodiment has a function of alignment. In detail, when the insulating sheet 140 is provided, when the corner portion of the insulating sheet 140 having the second groove 140b is in contact with the edge of the half-cut solar cell 112, it can be determined that the insulating sheet 140 has been aligned, and the insulating sheet 140 The light-receiving surface 110 a of the half-cut solar cell 112 is not covered and does not contact the bonding wire 150.

第二凹槽140b在第二方向E2上的寬度W6並無特別限制。然而,為避免絕緣片140的角落部覆蓋半切太陽能電池112的受光面110a,第二凹槽140b在第二方向E2上的寬度W6也需至少大於一距離使得絕緣片140的角落部與所述半切太陽能電池112保持間距。在一實施例中,第二凹槽140b在第二方向E2上的寬度W6為20mm~30mm,但本發明不以此為限。The width W6 of the second groove 140b in the second direction E2 is not particularly limited. However, in order to prevent the corners of the insulating sheet 140 from covering the light-receiving surface 110a of the half-cut solar cell 112, the width W6 of the second groove 140b in the second direction E2 must also be at least greater than a distance such that the corners of the insulating sheet 140 and the The half-cut solar cells 112 maintain a pitch. In an embodiment, the width W6 of the second groove 140b in the second direction E2 is 20 mm to 30 mm, but the present invention is not limited thereto.

In detail, a light-receiving surface 110a and a backlight surface 110b of each half-cut solar cell 112 are respectively provided with a set of bonding wires 150, one end of a set of bonding wires 150 is connected to the light-receiving surface 110a of one of the half-cut solar cells 112, and a set of The other end of the bonding wire 150 is connected to the backlight surface 110b of the other half-cut solar cell 112 adjacent thereto. The above set of bonding wires 150 includes at least one bonding wire for connecting the half-cut solar cells 112 in series in the first direction E1 to form a series of half-cut solar cells 112 arranged in the second direction E2. The material of the bonding wire 150 may be, for example, a metal or other materials having conductive properties.

請同時參照圖1B、圖1C、圖4A及圖4B,在一實施例中,當焊線150位於被第二匯流條130的短部130b覆蓋的半切太陽能電池112的受光面110a上且與第二匯流條130連接時,一串半切太陽能電池112的非切割側112S2在第一方向E1上面向接線區10c。由於焊線150於此處是在所述半切太陽能電池112的受光面110a上與第二匯流條130(位於背光面110b上)連接,因此焊線150與第二匯流條130的短部130b會對被上述兩者夾於其中的半切太陽能電池112產生剪刀效應,因此需將未經切割過的半切太陽能電池112的非切割側112S2面向接線區10c以承受由上述兩者產生的壓應力,如圖1B及圖4A所示。然而,若將經切割過的半切太陽能電池112的切割側112S1面向接線區10c,由於經切割後的物體在受到外力時傾向變形,而經切割過的半切太陽能電池112的切割側112S1已失去其原有的規則結構而更易傾向改變其外形,因此易受剪刀效應影響而損壞,如圖4B所示。Please refer to FIG. 1B, FIG. 1C, FIG. 4A and FIG. 4B at the same time. In one embodiment, when the bonding wire 150 is located on the light receiving surface 110a of the half-cut solar cell 112 covered by the short portion 130b of the second bus bar 130, When the two bus bars 130 are connected, the non-cut side 112S2 of a series of half-cut solar cells 112 faces the wiring area 10c in the first direction E1. Since the bonding wire 150 is connected to the second bus bar 130 (located on the backlight surface 110b) on the light receiving surface 110a of the half-cut solar cell 112, the bonding wire 150 and the short portion 130b of the second bus bar 130 are connected. The shear effect is generated on the half-cut solar cell 112 sandwiched by the two, so the uncut side 112S2 of the uncut half-cut solar cell 112 faces the wiring area 10c to withstand the compressive stress generated by the two, such as 1B and 4A. However, if the cut side 112S1 of the cut half-cut solar cell 112 faces the wiring area 10c, the cut side 112S1 of the cut half-cut solar cell 112 has lost its ability because the cut object tends to deform when subjected to an external force. The original regular structure tends to change its shape more easily, so it is easily damaged by the effect of scissors, as shown in FIG. 4B.

在一實施例中,當焊線150位於被第二匯流條130的短部130b覆蓋的半切太陽能電池112的背光面110b上且與第二匯流條130連接時,一串半切太陽能電池112的切割側112S1在第一方向E1上面向接線區10c。如圖1C及圖4A所示,由於焊線150於此處是在所述半切太陽能電池112的背光面110b上與第二匯流條130(位於背光面110b上)連接,因此,焊線150與第二匯流條130是位於同一平面而無上述的產生剪刀效應的問題。In one embodiment, when the bonding wire 150 is located on the backlight surface 110b of the half-cut solar cell 112 covered by the short portion 130b of the second bus bar 130 and is connected to the second bus bar 130, the cutting of a series of half-cut solar cells 112 is performed. The side 112S1 faces the wiring area 10c in the first direction E1. As shown in FIG. 1C and FIG. 4A, since the bonding wire 150 is connected to the second bus bar 130 (located on the backlight surface 110b) on the backlight surface 110b of the half-cut solar cell 112, the bonding wire 150 is connected to The second bus bar 130 is located on the same plane without the aforementioned problem of generating a scissors effect.

在一實施例中,多個旁路二極體160中的每一者連接於相鄰的第一匯流條120與第二匯流條130之間或者連接於兩個第二匯流條130之間。詳細地說,旁路二極體160例如設置於相鄰的第一匯流條120的短部120b與第二匯流條130的短部130b之間或者連接於兩個第二匯流條130的短部130b之間。請參照圖1D,本實施例的多個旁路二極體160可將半切太陽能電池112劃分成多個群組112a、112b、112c、112d、112e、112f,其中群組112a、112d共享一個旁路二極體160,群組112b、112e共享一個旁路二極體160且群組112c、112f共享一個旁路二極體160。舉例來說,當位於群組112a的單一個半切太陽能電池112損壞因而阻斷電流的流經路徑時,電流可藉由與已損壞的所述半切太陽能電池112所在的群組112a並聯的旁路二極體160流至下一個群組112b。在本實施例中,多個旁路二極體160設置於一個接線盒170中。由於第一匯流條120的短部120b以及第二匯流條130的短部130b則例如沿第一方向E1延伸集中至區域S中,因此多個旁路二極體160也設置於區域S中,因此可將多個旁路二極體160整合於一個接線盒170中,藉此可避免需設置多個接線盒而導致製程上的困難及降低成本。在本實施例中,旁路二極體160為三個。旁路二極體160可包括例如矽的半導體材料。In one embodiment, each of the plurality of bypass diodes 160 is connected between the adjacent first bus bar 120 and the second bus bar 130 or between the two second bus bars 130. In detail, the bypass diode 160 is, for example, disposed between the short portion 120 b of the adjacent first bus bar 120 and the short portion 130 b of the second bus bar 130 or connected to the short portions of the two second bus bars 130. 130b. Referring to FIG. 1D, the plurality of bypass diodes 160 in this embodiment can divide the half-cut solar cell 112 into a plurality of groups 112a, 112b, 112c, 112d, 112e, and 112f, where the groups 112a and 112d share one side. Group diodes 160b, groups 112b, 112e share one bypass diode 160 and groups 112c, 112f share one bypass diode 160. For example, when a single half-cut solar cell 112 located in group 112a is damaged and the current flow path is blocked, the current can be bypassed in parallel with the group 112a where the half-cut solar cell 112 is damaged. The diode 160 flows to the next group 112b. In this embodiment, a plurality of bypass diodes 160 are disposed in one junction box 170. Since the short portion 120b of the first bus bar 120 and the short portion 130b of the second bus bar 130 extend, for example, along the first direction E1 and are concentrated into the area S, a plurality of bypass diodes 160 are also provided in the area S. Therefore, a plurality of bypass diodes 160 can be integrated into one junction box 170, thereby avoiding the difficulty in manufacturing and reducing the cost due to the need to install multiple junction boxes. In this embodiment, there are three bypass diodes 160. The bypass diode 160 may include a semiconductor material such as silicon.

在一實施例中,一個接線盒170設置於背板100的另一表面,如圖2所示。接線盒170可例如包括用以與外部線路電性連接的結構,以透過第一匯流條120與第二匯流條130將半切太陽能電池陣列110產生的功率導出。In one embodiment, a junction box 170 is disposed on the other surface of the back plate 100, as shown in FIG. 2. The junction box 170 may, for example, include a structure for electrically connecting with external lines, so as to extract the power generated by the half-cut solar cell array 110 through the first bus bar 120 and the second bus bar 130.

在一實施例中,半切太陽能電池模組10可更包括多條第三匯流條180。多條第三匯流條180例如位於第一電池區10a與第二電池區10b遠離接線區10c的一側。位於一串半切太陽能電池112的末端的半切太陽能電池可藉由焊線150與第三匯流條180電性連接,以串聯沿第一方向E1排列的半切太陽能電池112,使半切太陽能電池陣列110可構成一迴路,如圖1D所示。In one embodiment, the half-cut solar cell module 10 may further include a plurality of third bus bars 180. The plurality of third bus bars 180 are located on the side of the first battery area 10a and the second battery area 10b far from the wiring area 10c, for example. The half-cut solar cells at the end of a string of half-cut solar cells 112 can be electrically connected to the third bus bar 180 through the bonding wire 150, and the half-cut solar cells 112 arranged in series along the first direction E1 are connected in series, so that the half-cut solar cell array 110 can Form a loop, as shown in Figure 1D.

綜上所述,本發明的半切太陽能電池模組藉由使第一匯流條與第二匯流條集中延伸至半切太陽能電池模組的背光面的中央區域,因此可將設置於其間的多個旁路二極體整合至一個接線盒中,以避免製程上的困難以及降低成本。此外,本發明在第一匯流條與第二匯流條之間設置具特殊設計的絕緣片,以使第一匯流條與第二匯流條能夠部分重疊地設置而減少接線空間的使用,且具特殊設計的絕緣片可避免所述絕緣片覆蓋半切太陽能電池的受光面,以降低因遮蔭所造成的發電損失。本發明另藉由在焊線位於被第二匯流條的短部覆蓋的半切太陽能電池的受光面上與位於背光面上的第二匯流條連接時,使一串半切太陽能電池的非切割側在第一方向上面向接線區,以避免剪刀效應的產生。In summary, the half-cut solar cell module of the present invention extends the first bus bar and the second bus bar to the central area of the backlight surface of the half-cut solar cell module in a concentrated manner. The circuit diodes are integrated into a junction box to avoid process difficulties and reduce costs. In addition, in the present invention, an insulating sheet with a special design is provided between the first bus bar and the second bus bar, so that the first bus bar and the second bus bar can be partially overlapped to reduce the use of wiring space.
