The ratio of the length L1 to the width W1 of the first solar cell 112 is greater than or equal to 2 and less than or equal to 6. The second series battery group 120 is located on the first series battery group 110 and includes a plurality of second solar cells 122 and a plurality of second wire groups 124 connecting the second solar cells 122 in series. The second solar cells 122 are arranged along the first direction, and there are a plurality of second gaps 123 between the second solar cells 122, so that the first solar cells 112 receive light from the second gaps 123, respectively. The ratio of the length L2 to the width W2 of the second solar cell 122 is greater than or equal to 2 and less than or equal to 6.
在本实施方式中，第二太阳能电池122置于第一太阳能电池112上方，且第一太阳能电池112之间具有第一间隙113，而第二太阳能电池122之间具有第二间隙123，且第一太阳能电池112分别从第二间隙123显露，使得第一太阳能电池112可分别从第二间隙123接收光线。利用这样的双层结构，使得在上视角度(即图1的视角)下的第一太阳能电池112与第二太阳能电池122呈现相邻的状态，而在侧视角度(即图2的视角)下的第一太阳能电池112与第二太阳能电池122呈现上下交错的状态。如此一来，虽然在太阳能电池模块100朝向太阳光源的一面(即上视角度下所呈现的一面)上可见第一太阳能电池112与第二太阳能电池122彼此相邻排列，但实际上第一太阳能电池112与第二太阳能电池122彼此为上下交错的关系，因此不必担心第一太阳能电池112与第二太阳能电池122之间因距离过近而产生线路短路的问题。In this embodiment, the second solar cell 122 is placed above the first solar cell 112, and the first solar cell 112 has a first gap 113, and the second solar cell 122 has a second gap 123, and A solar cell 112 is exposed from the second gap 123 respectively, so that the first solar cell 112 can receive light from the second gap 123 respectively. With such a double-layer structure, the first solar cell 112 and the second solar cell 122 at the top view angle (ie, the viewing angle of FIG. 1) are adjacent to each other, while at the side view angle (ie, the viewing angle of FIG. 2) The first solar cell 112 and the second solar cell 122 underneath are in a staggered state. In this way, although the first solar cell 112 and the second solar cell 122 can be seen to be arranged adjacent to each other on the side of the solar cell module 100 facing the solar light source (that is, the side presented from the top view), in fact the first solar cell The battery 112 and the second solar cell 122 are in a staggered relationship with each other, so there is no need to worry about the short circuit between the first solar cell 112 and the second solar cell 122 due to the close distance.
在本实施方式中，第一串联电池组110中的第一太阳能电池112与第二串联电池组120中的第二太阳能电池122均沿着第一方向平行排列，而这里所指的第一方向为第一太阳能电池112(或第二太阳能电池122)的宽度W1(或宽度W2)方向。也就是说，第一串联电池组110与第二串联电池组120彼此平行设置(如图2所示)。In this embodiment, the first solar cells 112 in the first series battery pack 110 and the second solar cells 122 in the second series battery pack 120 are both arranged in parallel along the first direction, and the first direction referred to here is It is the width W1 (or width W2) direction of the first solar cell 112 (or the second solar cell 122). In other words, the first series battery pack 110 and the second series battery pack 120 are arranged parallel to each other (as shown in FIG. 2).
同时参阅图1与图2，由于第二间隙123的距离约等于第一太阳能电池112的宽度W1，因此若以上视角度观察，第一太阳能电池112除了从第二间隙123显露外，还分别与相邻的第二太阳能电池122紧密排列。同理，由于第一间隙113的距离约等于第二太阳能电池122的宽度W2，因此若以下视角度观察，第二太阳能电池122除了从第一间隙113显露外，还分别与相邻的第一太阳能电池112紧密排列。也就是说，在水平方向上，第一太阳能电池112与第二太阳能电池122之间几乎不存在间距(即间距趋近于零)。1 and 2 at the same time, since the distance of the second gap 123 is approximately equal to the width W1 of the first solar cell 112, if viewed from above, the first solar cell 112 is exposed from the second gap 123, but also with The adjacent second solar cells 122 are closely arranged. In the same way, since the distance of the first gap 113 is approximately equal to the width W2 of the second solar cell 122, if viewed from the downward angle, the second solar cell 122 is exposed from the first gap 113 and is also connected to the adjacent first The solar cells 112 are closely arranged. That is, in the horizontal direction, there is almost no distance between the first solar cell 112 and the second solar cell 122 (that is, the distance approaches zero).
由于第一间隙113与第二间隙123的距离分别约等于第二太阳能电池122的宽度W2与第一太阳能电池112的宽度W1，因此第一太阳能电池112与第二太阳能电池122可在朝向太阳光源的一面(即上视角度下所呈现的一面)呈现紧密排列的状态。以此结构形成的太阳能电池模块100由于不必考虑第一太阳能电池112与第二太阳能电池122之间水平距离的因素，因此可在单位面积内设 置较多的太阳能电池，进而接收较多的太阳光，并在不需额外付出庞大成本的前提下，有效增加太阳能电池模块100中的受光区域与有效发电区域。Since the distance between the first gap 113 and the second gap 123 is approximately equal to the width W2 of the second solar cell 122 and the width W1 of the first solar cell 112, the first solar cell 112 and the second solar cell 122 can be facing the sun light source. One side (that is, the side presented from the top view angle) presents a tightly arranged state. The solar cell module 100 formed with this structure does not have to consider the factor of the horizontal distance between the first solar cell 112 and the second solar cell 122, so more solar cells can be arranged in a unit area, thereby receiving more sunlight , And effectively increase the light-receiving area and effective power generation area in the solar cell module 100 without paying extra huge costs.

In the same way, one end of the second wire group 124 in the second series battery group 120 is electrically connected to the upper surface of the second solar cell 122 (for example, connected to the positive electrode located on the upper surface of the second solar cell 122), and the other end It is electrically connected to the lower surface of the second solar cell 122 (for example, connected to the negative electrode located on the lower surface of the second solar cell 122).

Specifically, the confluence referred to here includes a variety of different circuit connection modes (such as series, parallel, parallel after series, series after parallel, or a combination thereof, etc.), that is, the confluence line 130 can be in various ways To converge the currents of each battery layer connected in series, for the convenience of description, take FIGS. 6 to 8 as examples.
举例来说，同时参阅图6及图7，当第一串联电池层210a中相邻的第一串联电池组110之间以串联的方式电性连接，且第二串联电池层220a中相邻的第二串联电池组120之间也以串联的方式电性连接时，汇流线路130可将第一串联电池层210a与第二串联电池层220a进一步并联以形成如图8所示的太阳能电池模块100c。相反地，当第一串联电池层210a中相邻的第一串联电池组110之间以并联的方式电性连接，且第二串联电池层220a中相邻的第二串联电池组120之间也以并联的方式电性连接时，汇流线路130可将第一串联电池层210a与第二串联电池层220a进一步串联以形成如图8所示的太阳能电池模块100c。同时参阅图6及图7，除了上文所描述的两种电路连接方式外，汇流线路130还可以其他方式电性连接第一串联电池层210a与第二串联电池层220a。举例来说，可将第一串联电池层210a中左侧的两个相邻的第一串联电池组110与第 二串联电池层220a中左侧的两个相邻的第二串联电池组120以串联的方式电性连接，并同时将第一串联电池层210a中右侧的两个相邻的第一串联电池组110与第二串联电池层220a中右侧的两个相邻的第一串联电池组120以串联的方式电性连接。随后，以汇流线路130将上述左侧串联后的第一串联电池层210a与第二串联电池层220a及右侧串联后的第一串联电池层210a与第二串联电池层220a进一步并联，以形成如图8所示的太阳能电池模块100c。然而，本发明不以上述为限，汇流线路130可以任何合适的方式汇流各个串联电池层的电流。For example, referring to FIGS. 6 and 7 at the same time, when the adjacent first series battery packs 110 in the first series battery layer 210a are electrically connected in series, and the adjacent first series battery packs 110a in the second series battery layer 220a are electrically connected When the second series battery packs 120 are also electrically connected in series, the bus line 130 can further connect the first series battery layer 210a and the second series battery layer 220a in parallel to form a solar battery module 100c as shown in FIG. 8 . Conversely, when the adjacent first series battery packs 110 in the first series battery layer 210a are electrically connected in parallel, and the adjacent second series battery packs 120 in the second series battery layer 220a are also electrically connected in parallel. When electrically connected in parallel, the bus line 130 may further connect the first series cell layer 210a and the second series cell layer 220a in series to form the solar cell module 100c as shown in FIG. 8. 6 and 7 at the same time, in addition to the two circuit connection modes described above, the bus line 130 can also electrically connect the first series battery layer 210a and the second series battery layer 220a in other ways. For example, the two adjacent first series battery packs 110 on the left side of the first series battery layer 210a and the two adjacent second series battery packs 120 on the left side of the second series battery layer 220a can be combined. The two adjacent first series battery packs 110 on the right side of the first series battery layer 210a and the two adjacent first series batteries 110 on the right side of the second series battery layer 220a are electrically connected in series. The battery pack 120 is electrically connected in series. Subsequently, the first series battery layer 210a and the second series battery layer 220a on the left side connected in series and the first series battery layer 210a and the second series battery layer 220a on the right side connected in series are further connected in parallel by the bus line 130 to form The solar cell module 100c shown in FIG. 8. However, the present invention is not limited to the above, and the bus line 130 can flow the current of each battery layer in series in any suitable manner.
根据本发明上述实施方式，第二太阳能电池122置于第一太阳能电池112上方，且第一太阳能电池112之间具有第一间隙113，而第二太阳能电池122之间具有第二间隙123，且第一太阳能电池112分别从第二间隙123显露，使得第一太阳能电池112可分别从第二间隙123接收光线。利用这样的双层结构，使得在上视角度下的第一太阳能电池112与第二太阳能电池122呈现相邻的状态，而在侧视角度下的第一太阳能电池112与第二太阳能电池122呈现上下交错的状态。如此一来，虽然在太阳能电池模块100、100a、100b、100c、100d朝向太阳光源的一面(即上视角度下所呈现的一面)上可见第一太阳能电池112与第二太阳能电池122彼此紧密排列，但实际上第一太阳能电池112与第二太阳能电池122彼此为上下交错的关系，因此不必担心第一太阳能电池112与第二太阳能电池122之间因距离过近而产生线路短路的问题。此外，由于以此结构形成的太阳能电池模块100、100a、100b、100c、100d不必考虑太阳能电池之间水平距离的因素，因此可在单位面积内设置较多的太阳能电池，有效增加太阳能电池模块100、100a、100b、100c、100d中的受光区域与有效发电区域。According to the above embodiment of the present invention, the second solar cell 122 is placed above the first solar cell 112, and there is a first gap 113 between the first solar cells 112, and a second gap 123 is provided between the second solar cells 122, and The first solar cells 112 are exposed from the second gap 123 respectively, so that the first solar cells 112 can receive light from the second gap 123 respectively. With such a double-layer structure, the first solar cell 112 and the second solar cell 122 in the top view angle are adjacent to each other, and the first solar cell 112 and the second solar cell 122 in the side view angle are present Staggered state. In this way, although on the side of the solar cell modules 100, 100a, 100b, 100c, 100d facing the sun light source (ie the side presented from the top view), it can be seen that the first solar cell 112 and the second solar cell 122 are closely aligned with each other However, in fact, the first solar cell 112 and the second solar cell 122 are in a staggered relationship, so there is no need to worry about the short circuit between the first solar cell 112 and the second solar cell 122 due to the short distance. In addition, because the solar cell modules 100, 100a, 100b, 100c, 100d formed with this structure do not have to consider the factor of the horizontal distance between the solar cells, more solar cells can be arranged in a unit area, effectively increasing the solar cell module 100 , 100a, 100b, 100c, 100d in the light receiving area and effective power generation area.
图12绘示根据本发明另一实施方式的太阳能电池模块100e的上视图。图13绘示图12的太阳能电池模块100e的侧视图。同时参阅图12及图13，在本发明另一实施方式中，太阳能电池模块100e可包含背板150及多个串并联电池层230。串并联电池层230置于背板150上方。类似于上述实施方式，每一个串并联电池层230包含多个串联电池组240(在图12及图13中仅绘示出一个串联电池组240)。每一个串联电池组240包含多个太阳能电池242及串联太阳能电池242的多个导线组250。每一个串联电池组240中的太阳能电池242沿太阳能电池242的宽度W方向排列，且太阳能电池242的长度L与宽度W的比例大于等于2且小于等于6。FIG. 12 shows a top view of a solar cell module 100e according to another embodiment of the present invention. FIG. 13 is a side view of the solar cell module 100e of FIG. 12. Referring to FIGS. 12 and 13 at the same time, in another embodiment of the present invention, the solar cell module 100e may include a back plate 150 and a plurality of battery layers 230 in series and parallel. The series-parallel battery layer 230 is placed above the back plate 150. Similar to the foregoing embodiment, each series-parallel battery layer 230 includes a plurality of series-connected battery packs 240 (only one series-connected battery pack 240 is shown in FIGS. 12 and 13). Each series battery group 240 includes a plurality of solar cells 242 and a plurality of wire groups 250 connecting the solar cells 242 in series. The solar cells 242 in each series battery group 240 are arranged along the width W direction of the solar cells 242, and the ratio of the length L to the width W of the solar cells 242 is greater than or equal to 2 and less than or equal to 6.
应了解到，位于同一层的串联电池组240之间除了可以串联的方式彼此电性连接之外，还可以并联的方式或串联与并联的组合的方式彼此电性连接。因此，在本实施方式中，以「串并联电池层」代指透过任何合适的方式将同一层的串联电池组240彼此电性连接而形成的电池层。It should be understood that, in addition to being electrically connected to each other in series, the series-connected battery packs 240 on the same layer can also be electrically connected to each other in parallel or a combination of series and parallel. Therefore, in this embodiment, the term “series-parallel battery layer” refers to a battery layer formed by electrically connecting the series battery packs 240 of the same layer to each other through any suitable method.
具体来说，太阳能电池模块100e与太阳能电池模块100～100d不同之处在于串并联电池层230的数量。在本实施方式中，串并联电池层230的数量可大于2，也就是说，除了上述实施方式中的双层结构外，还可包含本实施方式中的多层结构。举例来说，参阅图12及图13，图12及图13分别绘示当串并联电池层230的数量为3时的太阳能电池模块100e的上视图及侧视图。应了解到，串并联电池层230的数量并不以3为限，设计者可依实际需求调整所配置的串并联电池层230的数量。Specifically, the solar cell module 100e is different from the solar cell modules 100-100d in the number of battery layers 230 in series and parallel. In this embodiment, the number of battery layers 230 in series and parallel connections may be greater than 2, that is, in addition to the double-layer structure in the above embodiment, the multilayer structure in this embodiment may also be included. For example, referring to FIGS. 12 and 13, FIGS. 12 and 13 respectively show a top view and a side view of a solar cell module 100e when the number of battery layers 230 in series and parallel connections is three. It should be understood that the number of series and parallel battery layers 230 is not limited to 3, and the designer can adjust the number of series and parallel battery layers 230 configured according to actual needs.
在本实施方式中，每一个导线组250包含沿太阳能电池242的长度L方向平行排列的多个导线252，且每一个导线组250中的导线252的数量为2至20条，但并不以此为限，此数量可依设计者的需求而定。此外，太阳能电池模块100e更包含汇流线路130，汇流线路130设置在太阳能电池模块100e的一端，并与每一个串并联电池层230中末端的导线组250连接。如上述实施方式，汇流线路130可汇流各个串并联电池层230的电流，并进一步电性连接至其他电子装置。此外，汇流线路130可以任何合适的方式汇流各个串并联电池层230的电流。In this embodiment, each wire group 250 includes a plurality of wires 252 arranged in parallel along the length L direction of the solar cell 242, and the number of wires 252 in each wire group 250 is 2 to 20, but not limited to This is a limit, and the number can be determined according to the needs of the designer. In addition, the solar cell module 100e further includes a bus line 130. The bus line 130 is disposed at one end of the solar cell module 100e and is connected to the wire group 250 at the end of each series-parallel cell layer 230. As in the above-mentioned embodiment, the bus line 130 can converge the current of each series-parallel battery layer 230 and further electrically connect to other electronic devices. In addition, the bus line 130 can flow the current of each series-parallel battery layer 230 in any suitable manner.
如图13所示，太阳能电池模块100e还可在盖板140与串并联电池层230之间、各个串并联电池层230之间、以及串并联电池层230与背板150之间设置透明绝缘层160，透明绝缘层160可用于电性隔离各个串并联电池层230，且保护太阳能电池模块100e免于受到水氧侵蚀，并可结合各层以形成坚固、耐用的太阳能电池模块100e。在本实施方式中，透明绝缘层160可由包含乙烯/醋酸乙烯酯共聚物(ethylene-vinyl acetate,EVA)的材料制成，但并不用以限制本发明。As shown in FIG. 13, the solar cell module 100e can also be provided with a transparent insulating layer between the cover plate 140 and the series and parallel battery layers 230, between the series and parallel battery layers 230, and between the series and parallel battery layers 230 and the back plate 150. 160. The transparent insulating layer 160 can be used to electrically isolate each series-parallel battery layer 230, protect the solar cell module 100e from water and oxygen, and can combine the layers to form a strong and durable solar cell module 100e. In this embodiment, the transparent insulating layer 160 may be made of a material including ethylene-vinyl acetate (EVA), but it is not used to limit the present invention.
太阳能电池模块100e中其余的元件连接关系、材料与功效皆与上述太阳能电池模块100～100d相同，因此将不再重复赘述。The connection relationships, materials, and functions of the remaining components in the solar cell module 100e are the same as those of the solar cell module 100-100d, and therefore will not be repeated.
如图13所示，在本实施方式中，串并联电池层230包含顶部串联电池层230a、中间串联电池层230b及底部串联电池层230c。顶部串联电池层230a中 的太阳能电池242a之间具有多个间隙243a；中间串联电池层230b中的太阳能电池242b之间具有多个间隙243b；且底部串联电池层230c中的太阳能电池242c之间具有多个间隙243c。太阳能电池242b从间隙243a显露，且太阳能电池242c从间隙243a、243b显露。也就是说，太阳能电池242b可从间隙243a接收光线，且太阳能电池242c可从间隙243a、243b接收光线。在本实施方式中，太阳能电池242a、242b、242c具有约相同的宽度W，且同一个串并联电池层230中太阳能电池240之间的距离(即间隙243a、243b、243c的宽度)约为太阳能电池240的宽度W的两倍。然而，每一个串并联电池层230中的每一个太阳能电池242之间的排列关系与距离并不以图12及图13所示的排列方式为限，设计者可依实际需求进行调整。此外，当串并联电池层230的数量大于3时，每一个串并联电池层230中的每一个太阳能电池242之间的排列关系也可包含众多可能，均不用以限制本发明。As shown in FIG. 13, in this embodiment, the series-parallel battery layer 230 includes a top series battery layer 230a, a middle series battery layer 230b, and a bottom series battery layer 230c. There are multiple gaps 243a between the solar cells 242a in the top tandem cell layer 230a; the solar cells 242b in the middle tandem cell layer 230b have multiple gaps 243b; and the solar cells 242c in the bottom tandem cell layer 230c have gaps between them. Multiple gaps 243c. The solar cell 242b is exposed from the gap 243a, and the solar cell 242c is exposed from the gaps 243a, 243b. That is, the solar cell 242b can receive light from the gap 243a, and the solar cell 242c can receive light from the gaps 243a, 243b. In this embodiment, the solar cells 242a, 242b, 242c have about the same width W, and the distance between the solar cells 240 in the same series-parallel battery layer 230 (ie the width of the gaps 243a, 243b, 243c) is about The width W of the battery 240 is twice. However, the arrangement relationship and distance between each solar cell 242 in each series-parallel battery layer 230 are not limited to the arrangement shown in FIG. 12 and FIG. 13, and the designer can adjust it according to actual needs. In addition, when the number of series-parallel battery layers 230 is greater than 3, the arrangement relationship between each solar cell 242 in each series-parallel battery layer 230 may also contain many possibilities, which does not limit the present invention.
如图13所示，在太阳能电池模块100e中，顶部串联电池层230a中的太阳能电池242a于背板150上的垂直投影为P1、中间串联电池层230b中的太阳能电池242b于背板150上的垂直投影为P2、且底部串联电池层230c中的太阳能电池242c于背板150上的垂直投影为P3。在本实施方式中，投影P1、投影P2及投影P3彼此不重叠或部分重叠。具体来说，投影P1、P2、P3不论从下视角度(即太阳能电池模块100e背对太阳光源的一面)观察或从侧视角度观察(即图13的视角)皆不重叠。也就是说，若从上视角度(即太阳能电池模块100e朝向太阳光源的一面)观察，可以完整地看到每一个串并联电池层230(在本实施方式中为顶部串联电池层230a、中间串联电池层230b及底部串联电池层230c)中的每一个太阳能电池242(在本实施方式中为太阳能电池242a、242b、242c)，如此一来，便能确保太阳能电池模块100e中的每一个太阳能电池242皆能接收到太阳光，以达到有效利用太阳光的目的。As shown in FIG. 13, in the solar cell module 100e, the vertical projection of the solar cell 242a in the top series cell layer 230a on the back plate 150 is P1, the solar cell 242b in the middle series cell layer 230b on the back plate 150 The vertical projection is P2, and the vertical projection of the solar cell 242c in the bottom series cell layer 230c on the back plate 150 is P3. In this embodiment, the projections P1, P2, and P3 do not overlap or partially overlap each other. Specifically, the projections P1, P2, and P3 do not overlap regardless of whether they are viewed from a downward angle (that is, the side of the solar cell module 100e facing away from the solar light source) or from a side view (that is, the viewing angle of FIG. 13). That is to say, if viewed from the top view angle (that is, the side of the solar cell module 100e facing the solar light source), each series and parallel battery layer 230 (in this embodiment, the top series battery layer 230a, the middle series Each solar cell 242 (in this embodiment, solar cells 242a, 242b, 242c) in the battery layer 230b and the bottom series battery layer 230c), in this way, each solar cell in the solar cell module 100e can be secured 242 can receive sunlight to achieve the purpose of effective use of sunlight.
根据本发明上述实施方式，利用太阳能电池的双层结构，使得在上视角度下的第一太阳能电池与第二太阳能电池呈现相邻的状态，而在侧视角度下的第一太阳能电池与第二太阳能电池呈现上下交错的状态，因此不必担心第一太阳能电池与第二太阳能电池之间因距离过近而产生线路短路的问题。此外，以此结构形成的太阳能电池模块可在单位面积内设置较多的太阳能电池，有效增加太阳能电池模块中的受光区域与有效发电区域。此外，除了上述的双层结构外， 本发明的太阳能电池模块还可为多层结构。由于在多层结构中，各个串联电池层中的各个太阳能电池于背板上的垂直投影彼此不重叠或部分重叠，因此可确保太阳能电池模块中的每个太阳能电池皆能接受到太阳光，以达到有效利用太阳光的目的。According to the above-mentioned embodiment of the present invention, the double-layer structure of the solar cell is used, so that the first solar cell and the second solar cell in the upper view angle are adjacent to each other, and the first solar cell and the second solar cell in the side view angle are adjacent to each other. The two solar cells are in a staggered state, so there is no need to worry about the short circuit between the first solar cell and the second solar cell due to the close distance. In addition, the solar cell module formed with this structure can provide more solar cells per unit area, effectively increasing the light-receiving area and effective power generation area in the solar cell module. In addition, in addition to the above-mentioned double-layer structure, the solar cell module of the present invention may also have a multilayer structure. In the multi-layer structure, the vertical projections of each solar cell in each series cell layer on the backplane do not overlap or partially overlap each other, so it can ensure that each solar cell in the solar cell module can receive sunlight. To achieve the purpose of effective use of sunlight.
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。Of course, the present invention can also have various other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding All changes and deformations shall belong to the protection scope of the appended claims of the present invention.

In this way, although the first solar cell and the second solar cell are closely arranged on the side of the solar cell module facing the solar light source (that is, the side presented from the top view angle), the first solar cell and the second solar cell are actually The solar cells are in a staggered relationship, so there is no need to worry about short circuits between the first solar cell and the second solar cell due to the short distance between them. In addition, because the solar cell module formed with this structure does not have to consider the factor of the horizontal distance between the solar cells, more solar cells can be arranged in a unit area, and then receive more sunlight, effectively increasing the solar cell module Light receiving area and effective power generation area.
