Description
技术领域
本发明涉及光伏的技术领域,尤其涉及一种高反射高阻隔太阳能电池背板膜及其制备方法。
背景技术
背板(Backsheet)是用在太阳能组件背面,直接与外环境大面积接触的光伏封装材料,通常要求其具备卓越的耐长期老化(湿热、干热、紫外)、耐电气绝缘、水蒸气阻隔等性能。太阳能光伏背板位于太阳能电池板的背面,对电池片起保护和支撑作用,光伏背板的分类有多种,最常用的有两种,即按制造工艺分为涂布型和复合型;按含氟材料分为双面含氟背板、单面含氟背板、无氟背板三种。现有常用的双面含氟背板,电池背板膜的反射率低,太阳能电池片长期接受阳光的照射后,容易导致电池组件发热,影响电池寿命;同时,太阳光的长期照射,还容易导致背板膜的发黄和破裂,严重时导致电池无法正常使用。
发明内容
鉴于以上现有技术的不足之处,本发明提供了一种高反射高阻隔太阳能电池背板膜,以解决了现有太阳能电池背板膜整体一致性差,易于局部出现缺陷,及其在反射率、水汽阻隔、耐高温、耐候、抗冲击等性能方面存在的不足问题,以进一步使其满足恶劣环境下长期使用的寿命要求。
为达到以上目的,本发明采用的技术方案为:
一种高反射高阻隔太阳能电池背板膜,所述背板膜包括中间PET基膜及分别设置在所述PET基膜上表面和下表面的第一涂层和第二涂层,所述第一涂层包括Ag-MOFs材料包覆二氧化钛掺杂的氟树脂,所述Ag-MOFs材料包覆二氧化钛的掺杂量占第一涂层的质量比为30~40wt%。
本发明通过Ag-MOFs材料的添加,使大量高反射率的金属银离子均匀分布在第一涂层中,减少金属原子积聚,提升膜层整体反射性能;通过Ag-MOFs材料包覆二氧化钛,无需添加其他分散剂,即可使得二氧化钛均匀分布在氟树脂中,避免了由于纳米二氧化钛团聚效应导致其难以分散均匀,造成膜层局部性能缺陷的出现;通过Ag-MOFs材料包覆二氧化钛,还利于提升膜层加工性能。纳米二氧化钛的添加,不仅可提高背板膜的耐候性和耐磨性,而且还可协同金属银进一步提高其反射率。
优选地,所述Ag-MOFs材料为有机MOF配体和金属银离子配位自组装得到的金属有机框架材料,其中所述有机MOF配体如结构式I所示,其CAS号为:1660960-35-9,
本发明有机MOF配体带有多个羧基官能团,通过羧基官能团与银离子的结合,得到具有网络结构的MOF材料;同时由于有机MOF配体所带有的氟原子,使得得到的MOF材料较其他有机配体具有更加优异的疏水性能和耐候性能。
优选地,所述氟树脂为聚四氟乙烯(PTFE)、聚三氟氯乙烯(PCTFE)、聚偏氟乙烯(PVDF)、乙烯-四氟乙烯共聚物(ETFE)、乙烯-三氟氯乙烯共聚物(ECTFE)、聚氟乙烯(PVF)中的至少一种。
优选地,所述第一涂层还包括添加剂、双酚A环氧树脂、丙烯酸树脂;所述添加剂、双酚A环氧树脂和丙烯酸树脂分别占第一涂层的质量比为1.5~3.5wt%、5~15wt%和8~10wt%。通过双酚A环氧树脂和丙烯酸树脂的添加,使背板膜具有高阻隔性能,进一步提高了背板膜的疏水性能和降低氧渗透率。
优选地,所述第二涂层为氟树脂、改性环氧树脂、丙烯酸树脂中的至少一种组成。通过改性环氧树脂和丙烯酸树脂的共同作用,提高了第一涂层和第二涂层与中间PET基膜的粘结力,而且易于在太阳能电池背板上形成完整、平滑的膜层。
