Description

—种太阳能电池组件
技术领域
[0001] 本实用新型属于太阳能电池领域,尤其涉及一种太阳能电池组件。
背景技术
[0002] 在传统能源日渐匮乏的今天,太阳能作为一种清洁、高效、可靠、可持续的替代新能源正被广泛的应用于工农业生产及人们生活的各个领域。光伏电池组件作为光伏发电最重要的光电器件,在光伏发电、光伏建筑一体化的实践中占重要地位。光伏电池组件就是利用光生伏特效应把光能转化成电能的发电单元,由于室外工作环境恶劣,对其可靠性要求较闻。
[0003] 市场现有的光伏电池组件分为两种结构,一种是常规光伏电池组件,采用光伏玻璃作为顶层,TPT或其他高分子材料复合膜作为封装背板,用EVA或PVB作层压封装。采用这种传统结构进行光伏组件封装,转化效率低,光利用率低,且无装饰作用。另一种是双玻太阳能电池组件,采用光伏玻璃作为顶层和背板材料,中间安装太阳能电池组,用EVA或PVB材料进行层压封装。双玻光伏电池组件可以用作光伏幕墙与建筑结合,作为建筑体外围护的一部分,不仅能起到发电作用,还可以作为建筑产品,因此,双玻光伏电池组件在近几年得到快速发展。双玻光伏电池组件中,双面光伏玻璃增加了耐冲击性能,同时能够双面接收太阳光的照射,增加了组件的发电功率;此外还具有机械性能好、成本低、美观、使用寿命长等优点。但是,由于背板玻璃是透明的,其反光性差,太阳光绝大部分可以自由透过光电部分之外的空白区域,从而降低了对太阳辐射的利用率,影响光电转化效率进一步提高。
实用新型内容
[0004] 本实用新型为解决现有的太阳能电池组件的太阳光利用率低的技术问题,提供一种太阳光利用率高的太阳能电池组件。
[0005] 本实用新型提供了一种太阳能电池组件,包括依次层叠的盖板层、第一胶粘层、电池片组层、第二胶粘层和背板层;其中,所述背板层包括透明层,所述透明层与第二胶粘层粘结的一面设置有网络状反光层,所述网格状反光层的网格填补电池片之间及电池片边缘位置;所述盖板层与第一胶粘层粘结的一面设有锯齿。
[0006] 优选地,所述网格状反光层为平面结构。
[0007] 优选地,所述网格状反光层为高分子材料层。
[0008] 优选地,所述网格状反光层为氟碳树脂层、聚偏氟乙烯层、聚乙烯层、氟碳树脂改性聚合物层、聚偏氟乙烯改性聚合物层和聚乙烯改性聚合物层中的至少一种。具有高反射性,耐老化性优异等特点。
[0009] 优选地,所述锯齿的齿尖角度为45-135°。
[0010] 优选地,所述锯齿的齿尖角度为60-100°。
[0011] 优选地,所述锯齿的齿尖角度为60°。
[0012] 优选地,所述盖板层为光伏玻璃层、镀膜减反射玻璃层或者绒面增透玻璃层。[0013] 优选地,所述的盖板层和电池片组层之间夹持有第一胶粘层,所述的电池片组层和背板层之间夹持有第二胶粘层。
[0014] 优选地,所述透明层为玻璃层。
[0015] 优选地,电池片组为单晶电池片组或多晶电池片组。
[0016] 优选地,所述第一胶粘层和第二胶粘层各自独立为乙烯-醋酸乙烯共聚物或聚乙烯醇缩丁醛。
[0017] 本实用新型提供的太阳能电池组件:由于所述背板包括透明层和位于电池片间隙的网格状平面反光层,因此,光线可同时从组件前后两面入射到电池片上被电池片利用。同时,从盖板入射到电池片间隙的光线,在平面反光层进行平面反射,反射后的光线入射到盖板的锯齿面继续反射到电池片上利用,这样就进一步提高了光子的利用率,提高了光伏组件的输出功率。此外,网格状反光层与电池组正好形成一种机械铆合效果,更增加了光伏电池组件的机械稳定性,延长了使用寿命。
附图说明
[0018] 图1为本实用新型实施例的结构示意图;
[0019] 图2为本实用新型的光线反射示意图。

[0028] 本实用新型的太阳能电池组件,通过网格状反光层32及盖板一侧的锯齿将射入到电池片间隙的太阳光经过两次反射后进入电池片,这样就进一步提高了光子的利用率,提高了光伏组件的输出功率。
[0029] 以上所述仅为本实用新型的较佳实施例而已,并不用以限制本实用新型,凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本实用新型的保护范围之内。
