Abstract

本实用新型提供了一种不锈钢网封装结构的柔性组件,其包含柔性背板、第一热熔胶、太阳电池串、不锈钢网、第二热熔胶、柔性前板。所述柔性背板和柔性前板分别设置在第一热熔胶和第二热熔胶的外表面,所述太阳电池串和不锈钢网设置在第一热熔胶和第二热熔胶的中间;所述不锈钢网设置在太阳电池串外边缘四周的局部位置或全部位置并呈连续分布或分散分布。因为不锈钢具有高耐腐蚀性,耐高低温,耐氧化、及可塑性强的特性,同时不锈钢具有硬度高、强度好等优点,因此,在太阳电池串周围设置不锈钢网可以进一步加强柔性组件的强度,增加柔性组件的耐撕扯特性,即使在设置不锈钢网的位置打孔镶嵌金属拉扣柔性组件也不会被撕裂。

Description

一种不锈钢网封装结构的柔性组件
技术领域
本实用新型涉及太阳能电池、柔性太阳能电池领域,尤其涉及一种不锈钢网封装结构的柔性组件。
背景技术
柔性太阳能电池,由柔性背板、第一热熔胶、电池串、第二热熔胶、柔性前板依次敷设,层压形成柔性硅基电池模组,可以应用于太阳能背包、太阳能敞篷、太阳能汽车、太阳能帆船甚至太阳能飞机上,是太阳能电池的一种,具有技术先进、性能优良、成本低廉、用途广泛等优点。但是当柔性太阳能电池模组在高温高湿(温度85℃或湿度85%)的环境下测试1000个小时以上时会出现脱层、变形、焊带脱焊、产品发黄等现象。实际使用时,在比较恶劣的使用环境下,如高温或低温,高湿或干旱,风吹时间长风力大的情况下长时间使用,也会出现产品撕裂,内部因湿气浸入导致焊带氧化脱焊等现象。此外,柔性太阳电池组件在实际应用中为了方便悬挂或美观等用途需要在组件的边缘位置打孔并镶嵌金属扣,但因柔性前背板的强度不够,会在使用过程也会出现撕裂现象。以上均易造成柔性太阳能电池组件产品性能下降,影响柔性太阳能电池组件品质。
发明内容
为解决现有技术存在的缺陷,本实用新型提供了一种不锈钢网封装结构的柔性组件,其特征在于,所述不锈钢网封装结构的柔性组件包含柔性背板、第一热熔胶、太阳电池串、不锈钢网、第二热熔胶、柔性前板。所述柔性背板和柔性前板分别设置在第一热熔胶和第二热熔胶的外表面,所述太阳电池串和不锈钢网设置在第一热熔胶和第二热熔胶的中间;所述不锈钢网设置在太阳电池串外边缘四周的局部位置或全部位置并呈连续分布或分散分布。
优选的,所述不锈钢网,其材质为SUS302、304、304L、316、316L、310s等任意不锈钢网材质;其种类为不锈钢平纹网、不锈钢斜纹网、不锈钢竹花纹网、五综不锈钢网、不锈钢冲孔网或不锈钢勾花网等中的至少一种;其目数为20以下、20、30、40、60、80、80以上中的至少一种;其宽度及长度可根据太阳电池组件尺寸及太阳能组件安装的要求做不同的调节设计。
优选的,所述柔性背板为塑料薄膜ETFE、PI、PET、PEN、PVDF或含氟材料的复合膜中的一种。
优选的,所述第一热熔胶、第二热熔胶为EVA、Surlyn、POE中的一种。
优选的,所述的太阳电池串为单晶硅电池、多晶硅电池、硅基异质结、PERC、PERL、PERT、TOPCOM、IBC或HBC中的一种
优选的,所述柔性前板为塑料薄膜ETFE、PET、PEN、透明PVDF或含氟材料的透明复合膜中的一种。
由上述对本实用新型结构的描述可知,和现有技术相比,本实用新型具有如下优点:
本实用新型提供的不锈钢网封装结构的柔性组件,通过将不锈钢网设置在太阳电池串的外边缘四周的局部位置或全部位置并呈连续分布或分散分布。因为不锈钢具有高耐腐蚀性,耐高低温,耐氧化的特性,而且可塑性强,将不锈钢网铺设在太阳电池串的外边缘后再层压,可以有效保护太阳电池串,防止水汽等外部杂质入浸腐蚀太阳电池串,并造成产品氧化、焊带脱焊、产品发黄等现象,影响影响组件质量。再者,和PET等柔性背板相比,不锈钢具有硬度高、强度好等优点,因此,不锈钢网的设置可以进一步加强柔性组件的强度,增加柔性组件的耐撕扯特性,即使在设置不锈钢网的位置打孔镶嵌金属拉扣柔性组件也不会被撕裂。
