Definitions

  • the invention relates to a packaging film for a solar cell and a preparation method and application thereof.
  • the white film can be used in the lower layer of the module to improve the power of the component by reflecting visible light and near-infrared light. It can be applied to single glass components and double glass components. The appearance requirements of the components are relatively demanding, and it is required that the white film cannot overflow to the battery sheets, the bus bars, the solder ribbons, and there are no defects such as wrinkles.
  • Pre-crosslinking process The pre-crosslinking makes the film partially cross-linked, thereby achieving the purpose of controlling white overflow. Disadvantages: poor peeling force, the components are not heat-resistant.
  • low-melting finger process reduce the possibility of white overflow by reducing the resin melt finger.
  • Disadvantages The ability to control overflow is not the best, the components still have flanges.
  • non-woven composite process through a layer of non-woven fabric, to achieve control white

Description

一种太阳能电池用封装胶膜及其制备方法和应用 技术领域
本发明涉及一种太阳能电池用封装胶膜及其制备方法和应用。
背景技术
白色胶膜可以用在组件下层，通过反射可见光及近红外光达到提高组件功率的目的，可以应用在单玻组件及双玻组件上。对组件外观要求比较苛刻，要求白色胶膜不能上溢至电池片、汇流条、焊带上，同时不能有褶皱等缺陷。
现有技术中通常采用如下方案来解决白色胶膜的白色上溢问题：
1、预交联工艺：通过预交联使得胶膜部分交联，从而达到控制白色上溢的目的。缺点：剥离力差，组件不耐热烘。
2、低熔指工艺：通过降低树脂熔指来降低白色上溢的可能性。缺点：控制上溢的能力不算最好，组件仍有翻边。
3、无纺布复合工艺：通过复合一层无纺布，从而达到控制白
申请号为201710859687.8的发明专利公开了一种三层结构的太阳能电池封装胶膜及其制备方法，其通过在芯层中添加只能够由UVA紫外光引发交联反应的单酰基膦氧化物、双酰基膦氧化物、苯偶姻及其烷基醚、二烷氧基苯乙酮类、α-羟基烷基苯酮类、α-胺烷基苯酮类、二苯甲酮及其衍生物、硫杂蒽酮及其衍生物中的一种或多种光引发剂。但是，UVA的波长为320～400nm，在被固化材料为UV光遮挡材料，具体为芯层中的颜/填料(例如二氧化钛)对UVA具有阻隔作用，因此，当采用UVA照射含有颜/填料的芯层时，UVA会被阻隔，穿透能力有限，从而影响交联反应的深度，导致交联效果不好，同时残存未交联小分子多，会游离出来影响组件的抗PID，抗蜗牛纹等性能。另外，UVA对人体的伤害较大，长期暴露于UVA下容易致癌，不利于人员安全操作。
