具体实施方式
如图1所示，图1是根据本公开的一个实施例的一种太阳能电池组件的电池串的示意图，太阳能电池组件包括多个电池串10，其中：
每个电池串10包括多个串联的电池片11、设置于每相邻两个电池片11之间的导电结构12以及支撑传热块13。
电池串10的每相邻两个电池片11中，第一电池片的背面与第二电池片的正面之间存在重叠区域；电池片受光面为电池片的正面，电池片背光面为电池片的背面。其中，电池串10中任意一个电池片11均可作为第一电池片，与该第一电池片相邻的、且正面与第一电池片的背面存在重叠区域的电池片11则为第二电池片；相对应地，电池串10中任意一个电池片11均可作为第二电池片，与该第二电池片相邻的、且背面与第二电池片的正面存在重叠区域的电池片11则为第一电池片。
导电结构12的一部分或者全部位于重叠区域的部分区域，用于将相邻的两个电池片11串联，导电结构12可以为导电胶条或者金属焊带。如图1至图4所示，相邻两个电池片以焊带作为导电结构12，导电结构12的一部分位于重叠区域的部分区域；如图7至图11所示，相邻两个电池片以导电胶条作为导电结构，导电结构12的全部位于重叠区域的部分区域。
支撑传热块13的一部分或全部设置于重叠区域内未设置导电结构12的区域，以对重叠区域内未设置导电结构的区域进行支撑，防止由 于导电结构的存在导致重叠区域的不完全贴合、使得电池片受力不均产生隐裂甚至热斑损坏、以及由于隐裂甚至热斑效应过度消耗组件能量，从而提高太阳能电池组件的稳定性及发电效率；相应地，支撑传热块13可以为电池片11散热，从而提高太阳能电池组件的热传导效率，降低高温影响，提高组件的发电效率。
在本公开实施例中，支撑传热块13可以将重叠区域内未设置导电结构12的区域全部填充，也可以仅填充一部分。
在本公开的实施例中，支撑传热块包括聚合物、高导热材料、助剂等的一种或多种复合体系，以实现对重叠区域的支撑作用；还包括金属、聚合物基材、石墨和陶瓷材料中的任意一种或多种导热材料，以实现散热作用。其中，聚合物体系可以为有机硅、聚烯烃、聚氨酯、环氧树脂和丙烯酸胶中的任意一种或多种；支撑传热块的热传导系数可以大于1W/(m.K)；支撑传热块可以为导电体或非导电体。示例性地，支撑传热块的热传导系数可以根据实际需要进行设定，在日照充足的地区，选择热传导系数高的导热材料；在日照较少的地区，选择热传导系数低的导热材料。支撑传热块是否导电也可以根据实际需要进行设定，根据需要选择合适的材料即可。
在本公开的实施例中，在设置支撑传热块13时，可以将支撑传热块13设置于电池片11的背面。如图1所示，当支撑传热块13的一部分设置于重叠区域内未设置导电结构12的区域时，支撑传热块13的剩余部分位于相邻两个电池片11中的第一电池片的背面。通过将支撑传热块设置于电池片的背面，在支撑传热块的一部分设置于重叠区域时，可以减少支撑传热块对电池片受光面积的遮挡，提高太阳能电池组件的发电效率。
在本公开的实施例中，如图1、图2、图3所示，电池串10为叠焊式电池串，电池串10包括多个导电结构12和多个支撑传热块13， 多个支撑传热块13与多个导电结构12交替排列，导电结构12为金属焊带，即多个支撑传热块13与多条金属焊带交替排列。通过支撑传热块与金属焊带交替排列，使得支撑传热块可以填充电池片之间的重叠区域内未设置金属焊带的区域，从而对重叠区域内未设置金属焊带的区域进行支撑，防止由于金属焊带的存在导致重叠区域的不完全贴合、电池片产生隐裂甚至热斑现象，从而提高太阳能电池组件的稳定性及发电效率；进一步地，支撑传热块可以为电池片散热，从而提高太阳能电池组件的热传导效率，防止高温对电池片的影响，提高组件的发电效率。
在本公开的实施例中，如图1、图2、图3所示，当电池串10为叠焊式电池串时，导电结构12即金属焊带的一部分位于重叠区域的部分区域，用于将相邻的两个电池片11串联。替换性地，也可以选择性地设置金属焊带的全部位于重叠区域的部分区域，只要可以实现导电结构的引流作用即可。
在本公开的实施例中，如图1、图2、图4所示，沿导电结构12的引流方向，支撑传热块13的长度不小于重叠区域的宽度，当电池串10为叠焊式电池串时，即沿金属焊带的引流方向(如图2所示的第一方向)，支撑传热块13的长度L不小于重叠区域的宽度W。如图1所示，当支撑传热块13的长度L大于重叠区域的宽度W时，支撑传热块13的一部分设置于重叠区域内未设置金属焊带的区域，为电池片11散热；如图4所示，当支撑传热块13的长度L等于重叠区域的宽度W时，支撑传热块13的全部设置于重叠区域内未设置金属焊带的区域，为电池片11散热。通常情况下，设置支撑传热块的长度等于重叠区域的宽度，可以满足支撑重叠区域内未设置金属焊带的区域、保证相邻电池片的完全贴合以提高太阳能电池组件的稳定性及发电效率的技术效果；进一步地，为了获得更好的组件稳定性的技术效果，可以设置支撑传热块的长度大于重叠区域的宽度，确保重叠区域内未设置金属焊带的区域被充分填充，使得电池片完全贴合，提高电池组件的发电 效率。
在本公开的实施例中，当电池串为叠焊式电池串时，可以选择性地设置金属焊带的一部分或者全部位于重叠区域的部分区域，同时设置支撑传热块的一部分或全部设置于重叠区域内未设置金属焊带的区域。
在本公开的实施例中，沿电池片11的重叠方向(如图4所示的第二方向)，导电结构12和支撑传热块13的高度相同，即金属焊带和支撑传热块13的高度相同。通过设置导电结构和支撑传热块的高度相同，即设置金属焊带和支撑传热块的高度相同，可以确保重叠区域内未设置金属焊带的区域被填充，使得电池片完全贴合，防止不完全贴合导致电池片产生隐裂甚至热斑现象，从而提高太阳能电池组件的稳定性及发电效率。
在本公开的实施例中，还包括：当电池串10为叠焊式电池串时，导电结构12为金属焊带，电池片11的正面设置有正面主栅线，电池片11的背面设置有背面主栅线，相邻两个电池片11中的第二电池片的正面主栅线与第一电池片的背面主栅线通过金属焊带连接，金属焊带收集电池片11产生电流；其中，金属焊带可以为圆焊带、三角焊带、扁平焊带或异形焊带等。通过金属焊带串联电池片以形成电池串，可以保证电池片连接的稳固性。
在本公开的实施例中，当电池串10为叠焊式电池串时，太阳能电池组件的六并三串电路图如图5所示，太阳能电池组件的五并两串电路图如图6所示；其中：每个电池串10包括多个串联的电池片11、设置于每相邻两个电池片11之间的导电结构12(即金属焊带)、以及与金属焊带交替排列的支撑传热块13。
在本公开的实施例中，如图7、图8、图9、图10、图11所示， 电池串10为叠瓦式电池串，电池串10包括导电结构12和支撑传热块13，支撑传热块13设置于导电结构12的至少一侧，导电结构12为导电胶条，即支撑传热块13设置于导电胶条的至少一侧；其中，图8至图11中的虚线框表示相邻两个电池片的重叠区域。
如图7、图8所示，导电胶条设置于重叠区域的中间部位，相应地，将两个支撑传热块13分别设置于导电胶条的两侧，远离第一电池片背面边缘的支撑传热块为第一支撑传热块，靠近第一电池片背面边缘的支撑传热块为第二支撑传热块，设置第二支撑传热块远离导电胶条的边缘与第一电池片背面的边缘齐平；或者，如图9所示，导电胶条设置于第一电池片背面的边缘，且导电胶条的一侧边缘与第一电池片背面的边缘齐平，相应地，将支撑传热块13设置于导电胶条远离第一电池片背面边缘的另一侧。根据导电胶条的不同设置位置，在其至少一侧布置支撑传热块，使得支撑传热块可以填充电池片之间的重叠区域内未设置导电胶条的区域，从而对重叠区域内未设置导电胶条的区域进行支撑，防止由于导电胶条的存在导致重叠区域的不完全贴合、电池片产生隐裂甚至热斑现象，从而提高太阳能电池组件的稳定性及发电效率；进一步地，支撑传热块可以为电池片散热，从而提高太阳能电池组件的热传导效率，防止高温对电池片的影响，提高组件的发电效率。
在本公开的实施例中，如图8、图9所示，当电池串10为叠瓦式电池串时，导电结构12即导电胶条的全部位于重叠区域的部分区域，用于将相邻的两个电池片11串联。替换性地，也可以选择性地设置导电胶条的一部分位于重叠区域的部分区域，只要可以实现导电结构的引流作用即可。
在本公开的实施例中，如图7、图8、图9所示，导电结构12的宽度与支撑传热块13的宽度之和不小于重叠区域的宽度W，当电池串10为叠瓦式电池串时，即导电胶条的宽度与支撑传热块13的宽度之和 不小于重叠区域的宽度W。当导电胶条的宽度与支撑传热块13的宽度之和大于重叠区域的宽度W时，如图8所示，将两个支撑传热块13分别设置于导电胶条的两侧，第一支撑传热块的一部分设置于重叠区域内未设置导电胶条的区域，第二支撑传热块的全部设置于重叠区域内未设置导电胶条的区域，使得第一支撑传热块和第二支撑传热块填充重叠区域内未设置导电胶条的区域，并为电池片11散热；如图9所示，导电胶条设置于第一电池片背面的边缘，将支撑传热块13设置于导电胶条远离第一电池片背面边缘的另一侧，支撑传热块13的一部分设置于重叠区域内未设置导电胶条的区域。
当导电胶条的宽度与支撑传热块13的宽度之和等于重叠区域的宽度W时，如图10所示，将两个支撑传热块13分别设置于导电胶条的两侧，第一支撑传热块的全部和第二支撑传热块的全部设置于重叠区域内未设置导电胶条的区域，使得第一支撑传热块和第二支撑传热块填充重叠区域内未设置导电胶条的区域，并为电池片11散热；如图11所示，导电胶条设置于第一电池片背面的边缘，将支撑传热块13设置于导电胶条远离第一电池片背面边缘的另一侧，支撑传热块13的全部设置于重叠区域内未设置导电胶条的区域。
通常情况下，设置导电胶条的宽度与支撑传热块的宽度之和等于重叠区域的宽度，可以满足支撑重叠区域内未设置导电胶条的区域、保证相邻电池片的完全贴合以提高太阳能电池组件的稳定性及发电效率的技术效果；进一步地，为了获得更好的组件稳定性的技术效果，可以设置导电胶条的宽度与支撑传热块的宽度之和大于重叠区域的宽度，确保重叠区域内未设置导电胶条的区域被充分填充，使得电池片完全贴合，提高电池组件的发电效率。
在本公开的实施例中，当电池串为叠瓦式电池串时，可以选择性地设置导电胶条的一部分或者全部位于重叠区域，同时设置支撑传热块的一部分或全部设置于重叠区域。
在本公开的实施例中，沿电池片11的重叠方向，导电结构12和支撑传热块13的高度相同，即导电胶条和支撑传热块13的高度相同。通过设置导电结构和支撑传热块的高度相同，即设置导电胶条和支撑传热块的高度相同，可以确保重叠区域内未设置导电胶条的区域被填充，使得电池片完全贴合，防止不完全贴合导致电池片产生隐裂甚至热斑现象，从而提高太阳能电池组件的稳定性及发电效率。
在本公开的实施例中，当电池串10为叠瓦式电池串时，支撑传热块13的长度与导电结构12的长度相同，导电结构12的长度不小于重叠区域的长度，即支撑传热块13的长度与导电胶条的长度相同，导电胶条的长度不小于重叠区域的长度。通过设置支撑传热块的长度与导电结构的长度相同，即设置支撑传热块和导电胶条的长度相同，并且两者的长度不小于重叠区域的长度，使得支撑传热块和导电胶条可以充分填充重叠区域，确保电池片完全贴合，防止不完全贴合导致电池片产生隐裂甚至热斑现象，从而提高太阳能电池组件的稳定性及发电效率。
在本公开的实施例中，如图12所示，当电池串10为叠焊式电池串时，支撑传热块13可以包括支撑部131和传热部132，沿相邻两个电池片11的重叠方向，支撑部131和传热部132交替设置。其中，支撑部131的材料可以是有机硅、聚烯烃、聚氨酯、环氧树脂和丙烯酸胶中的任意一种或多种聚合物，传热部132的材料可以是金属、聚合物基材、石墨和陶瓷材料中的任意一种或多种导热材料。
在本公开的实施例中，如图13所示，当电池串10为叠瓦式电池串时，支撑传热块13可以包括支撑部131和传热部132，沿相邻两个电池片11的重叠方向，支撑部131和传热部132交替设置。其中，支撑部131的材料可以是有机硅、聚烯烃、聚氨酯、环氧树脂和丙烯酸胶中的任意一种或多种聚合物，传热部132的材料可以是金属、聚合 物基材、石墨和陶瓷材料中的任意一种或多种导热材料。
在本公开的实施例中，通过支撑部131和传热部132交替设置的支撑传热块13，直接将支撑部和传热部交替印刷于电池全片上，无需经过支撑材料和传热材料混合以形成支撑传热块的步骤，一方面，可以简化太阳能电池组件的生产流程；另一方面，传热材料直接暴露于空气中，可以进一步提高支撑传热块的热传导效率，从而提高太阳能电池组件的稳定性及发电效率。
