Description

一种电极隔离结构体及一种太阳能电池组件
技术领域
本发明涉及太阳能电池组件领域，尤其涉及一种可用于太阳能电池组件的电极隔离结构体，以及一种包括电极隔离结构体的太阳能电池组件。
背景技术
如图1所示，一般太阳能电池组件包括玻璃2，两个EVA层3，被封装在所述两个EVA层3之间的太阳能电池片4以及背板5。为了防止太阳能电池片4的正极6和负极7接触发生短路，通常在正极6和负极7之间设置有电极隔离结构体8。为了提高太阳能电池组件的功率，可以选用紫外线透过的封装EVA材料作为EVA层3，但是，这样会导致被封装在EVA层3中的电极隔离结构体8受到紫外线照射而变黄，进而影响太阳能电池组件的稳定性及外观。此外，在正负汇流条及焊带结点处，常常存在锡渣堆砌，焊带与汇流条焊烙点面积过大，电极隔离结构体8在湿热老化过程中，容易在焊烙点处出现脱层等外观缺陷。
发明内容
本发明旨在提供一种可用于太阳能电池组件的电极隔离结构体，不仅具有良好的耐候性能(抗紫外线性能，耐湿热老化性能)，而且提高了电极隔离结构体与太阳能电池、汇流条之间的粘结力。
根据本发明的一个方面，提供了一种电极隔离结构体，该电极隔离结构体包括：交联抗紫外EVA层，包括偶联剂、紫外线吸收剂、紫外线稳定剂、乙烯-醋酸乙烯酯EVA粒子、和重量百分比小于2％的过氧化类交联剂；第一粘结层，选自以下涂层的一种或它们的组合：含乙烯-醋酸乙烯酯EVA粒子的涂层、丙烯酸类涂层、氟树脂涂层、聚氨酯涂层、环氧树脂涂层；聚酯树脂层；和第二粘结层，包括乙烯-醋酸乙烯酯EVA粒子。
根据某些具体实施方式，在所述交联抗紫外EVA层中，所述乙烯-醋酸乙烯酯EVA粒子中醋酸乙烯酯的含量为5％～45％。
根据某些具体实施方式，所述交联抗紫外EVA层中的乙烯-醋酸乙烯酯EVA粒子的熔融流动指数大于10。

第一粘结层82具有抗紫外线功能及粘结功能，可以由95～99重量％乙烯-醋酸乙烯酯EVA粒子，0～5重量％紫外线稳定剂和0～5重量％偶联剂组成。其厚度介于5μm到100μm之间，优选为30μm。
在第一粘结层中，所使用的偶联剂的种类可以是，硅烷类或钛酸酯类等。紫外线稳定剂可选用例如巴斯夫公司的TINUVIN 622，TINUVIN 770等，还有氰特公司的CYASORB UV1164，CYASORB UV 2126，及CYASORB THT系列产品等。可优选的乙烯-醋酸乙烯酯EVA粒子的熔融流动指数(MFI)大于10，更优选地，MFI为10～50，其中醋酸乙烯酯(VA)的含量为5％～45％，例如，可以选用台塑科技的TAISOX7660MEVA。
此外，第一粘结层也可以使用丙烯酸类涂层，氟树脂涂层，聚氨酯涂层，环氧树脂涂层，或者各类偶联剂涂层，其厚度可以为1～20μm。

制备方法
本发明的电极隔离结构体的一种示例性的制备方法如下：
为了制备本发明的交联抗紫外EVA层，可以将EVA粒子3与过氧化类交联剂，偶联剂，紫外线吸收剂，紫外线稳定剂按一定比例，在常温(10～30℃)下混合搅拌均匀，加热后制备成交联抗紫外EVA膜。
同样的将EVA粒子2与偶联剂，紫外线稳定剂按一定比例，在常温(10～30℃)下混合搅拌均匀，加热后制备成第一粘结膜。
使用EVA粒子1，在聚酯树脂的一个面上制备30μm的第二粘结层。然后在聚酯树脂的另一个面上涂覆已经制备的30μm第一粘结膜。最后，在第一粘结膜上涂覆已经制备的140μm交联抗紫外EVA膜，制得电极隔离结构体样品。
本发明通过“紫外辐照测试”来评价电极隔离结构体的抗紫外线性能，通过“剥离力测试”来评价电极隔离结构体的粘结性能，通过“湿热老化测试”来评价电极隔离结构体的耐湿热老化性能。
紫外辐照测试
按照ASTM G154 cycle 1，将制得的电极隔离结构体样品，置于QUV加速老化箱体内，交联抗紫外EVA层朝向紫外光辐照灯源。
在150kWh/m2的累计紫外光辐照剂量下，用HUNTERLAB仪器按照ASTM E313测试电极隔离结构体的黄化指数(Yellowness Index，YI)。一般认为，YI小于10，电极隔离结构体的抗紫外线性能符合要求；YI小于5，电极隔离结构体的抗紫外线性能较好；YI小于3，电极隔离结构体的抗紫外线性能非常显著。
剥离力测试
将玻璃、封装EVA、太阳能电池片以及根据本发明的制备方法制得的电极隔离结构体样品，依次层叠热压后封装。然后，按照ASTM D903标准，使用INSTRON测试仪器来测试电极隔离体与电池片之间的剥离强度。
将玻璃、封装EVA、汇流条以及根据本发明的制备方法制得的电极隔离结构体样品，依次层叠热压后封装。然后，按照ASTM D903标准，使用INSTRON测试仪器来测试电极隔离体与汇流条之间的剥离强度。
一般认为，剥离强度大于5N/cm，电极隔离结构体的粘结力符合要求；玻璃强度大于10N/cm，电极隔离结构体的粘结力效果显著。测试中，如果电池片自身破裂而电极隔离结构体与电池片尚未分离，则认为电极隔离结构体的粘结力效果极佳。
湿热老化测试
将玻璃、封装EVA、汇流条、太阳能电池片以及根据本发明的制备方法制得的电极隔离结构体样品，如图1所示依次层叠热压后封装，制得太阳能电池组件样品。将太阳能电池组件样品分别置于85％湿度85℃温度的老化箱体内老化2000h。目测太阳能电池组件中，在电极隔离结构体处有无发生鼓包，脱层等外观不良，特别是在汇流条焊点与电极隔离结构体的重叠处。一般认为，出现鼓包、脱层等外观缺陷时，认为湿热老化性能不良；无鼓包、脱层等外观缺陷，则认为湿热老化性能合格。

如表4所示，根据本发明的电极隔离结构体的抗紫外线性能符合要求，电极隔离结构体和太阳能电池片、汇流条之间的粘结力符合要求，并且电极隔离结构体的耐湿热老化性能也符合要求。
发明人经研究发现，在现有的电极隔离结构体中，添加交联抗紫外EVA层，并且交联抗紫外EVA层中的EVA粒子、过氧化类交联剂、偶联剂、紫外线吸收剂和紫外线稳定剂相互协同效应，能够同时提高抗紫外线性能以及电极隔离结构体的粘结强度。但是，如果过氧化类交联剂加入过多(如对比例3～5)，过氧化类交联剂极易残存，则会导致太阳能电池组件在层压及湿热老化后，电极隔离结构体周围出现鼓包、脱层等外观缺陷，不符合要求。因此，为了使电极隔离结构体具有一定的抗湿热老化性能，过氧化类交联剂加入的含量应小于2％。
非过氧化类交联剂代替过氧化类交联剂加入交联抗紫外EVA层(如：对比例2)，虽然也能一定程度上提高电极隔离结构体的粘结强度。但是，其粘结性能远不如过氧化类交联剂的加入。此外，太阳能电池组件在层压及湿热老化后，加入非过氧化类交联剂的电极隔离结构体周围会出现鼓包、脱层等外观缺陷，不符合要求。
当交联抗紫外EVA层中的紫外线吸收剂添加量达2％，紫外线稳定剂添加量达0.7％时，电极隔离结构体在150kWh/m2的紫外光辐照强度下，黄化指数能小于5。而未添加紫外线吸收剂和紫外线稳定剂的电极隔离结构体(如：对比例1)的黄化指数则会达到30以上。
其中，特别的，当过氧化类交联剂添加量为1重量％，偶联剂添加量为1重量％，紫外线吸收剂添加量为2重量％，紫外线稳定剂添加量为0.7重量％时，且第一粘结层为含乙烯-醋酸乙烯酯EVA粒子的涂层时，能够实现最佳技术效果，且最经济。
在本发明中，第一粘结层也可以选用耐候性的丙烯酸类涂层(如：实施例11)，所制得的电极隔离结构体也能满足本发明的抗紫外线性能、粘结性能及耐湿热老化性能。但是，在实际使用中，电极隔离结构体的交联抗紫外EVA层与聚酯树脂层之间的剥离力没有第一粘结层选用含乙烯-醋酸乙烯酯EVA粒子的涂层强，且成本也相应较贵。
上述本发明的具体实施例仅例示性的说明了本发明的原理及其功效，而非用于限制本发明，熟知本领域的技术人员应明白，在不偏离本发明的精神和范围的情况下，对本发明所作的任何改变和改进都在本发明的范围内。本发明的保护范围，应以本发明所附的权利要求书所界定的范围为准。
