Abstract

本发明涉及一种具有高散热性能的太阳能电池背板，包括PET基材，所述PET基材的一侧通过粘结层连接耐候层，于所述耐候层的上表面设置无机绝缘层，于所述PET基材的另一端通过粘结层连接耐候粘结层，所述无机绝缘层含有钛白粉、聚酰亚胺及聚四氟乙烯，所述钛白粉为偶联剂改性的钛白粉。本发明结构简单、使用方便，本发明中无机绝缘层含有钛白粉、聚酰亚胺及聚四氟乙烯，聚酰亚胺材料在分子链上含有亚芳基或杂环结构，因此具有耐高温、耐辐射和耐电压的能力，因此本发明的太阳能电池背板具有寿命长的优点，钛白粉的设置使制得的太阳能背板颜色变白，进而减少太阳光的吸收，增加光反射，使得太阳能背板表面温度较低，增加电池输出效率。

Description

一种具有高散热性能的太阳能电池背板
技术领域
本发明涉及太阳能组件领域，尤其涉及一种具有高散热性能的太阳能电池背板。
背景技术
太阳能作为一种绿色环保、取之不尽的能源，无疑是取代传统火力发电的最佳选择，由于太阳能电池需要长期暴露在室外实用，所以光伏组件中的电池片需要加以保护，来防止大气中的水汽、氧气、紫外线等环境因素的影响和俯视。太阳能背板是整个太阳能电池的配件之一，主要起力学支撑和保护电池片免受环境因素渗透的作用，目前常规的太阳能电池背板的整体机械强度不高，在长时间使用后水汽易渗透到密封层中，影响电池片的寿命。
发明内容
本申请人针对上述现有问题，进行了研究改进，提供一种具有高散热性能的太阳能电池背板，其具有物美价廉、散热性好的优点。
本发明所采用的技术方案如下：
一种具有高散热性能的太阳能电池背板，包括PET基材，所述PET基材的一侧通过粘结层连接耐候层，于所述耐候层的上表面设置无机绝缘层，于所述PET基材的另一端通过粘结层连接耐候粘结层，所述无机绝缘层含有钛白粉、聚酰亚胺及聚四氟乙烯，所述钛白粉为偶联剂改性的钛白粉。
其进一步技术方案在于：
所述无机绝缘层的厚度为15～120μm。
本发明的有益效果如下：
本发明结构简单、使用方便，本发明中无机绝缘层含有钛白粉、聚酰亚胺及聚四氟乙烯，聚酰亚胺材料在分子链上含有亚芳基或杂环结构，因此具有耐高温、耐辐射和耐电压的能力，因此本发明的太阳能电池背板具有寿命长的优点，钛白粉的设置使制得的太阳能背板颜色变白，进而减少太阳光的吸收，增加光反射，使得太阳能背板表面温度较低，增加电池输出效率。
附图说明
图1为本发明的结构示意图。
其中：1、耐候层；2、粘结层；3、PET基材；4、耐候粘结层；5、无机绝缘层。
具体实施方式
下面说明本发明的具体实施方式。
如图1所示，一种具有高散热性能的太阳能电池背板包括PET基材3，PET基材3的一侧通过粘结层2连接耐候层1，于耐候层的上表面设置无机绝缘层5，于PET基材3的另一端通过粘结层2连接耐候粘结层4，无机绝缘层含有钛白粉、聚酰亚胺及聚四氟乙烯，钛白粉为偶联剂改性的钛白粉。上述无机绝缘层5的厚度为15～120μm。
本发明结构简单、使用方便，本发明中无机绝缘层含有钛白粉、聚酰亚胺及聚四氟乙烯，聚酰亚胺材料在分子链上含有亚芳基或杂环结构，因此具有耐高温、耐辐射和耐电压的能力，因此本发明的太阳能电池背板具有寿命长的优点，钛白粉的设置使制得的太阳能背板颜色变白，进而减少太阳光的吸收，增加光反射，使得太阳能背板表面温度较低，增加电池输出效率。
以上描述是对本发明的解释，不是对发明的限定，本发明所限定的范围参见权利要求，在不违背本发明的基本结构的情况下，本发明可以作任何形式的修改。
