技术领域
本发明涉及太阳能组件领域，尤其涉及一种高效率太阳能背板结构。
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，目前常规的太阳能背板虽然能提升光利用率，但是仍有大多数光仍被折射、反射等光学行为消耗在介质中或物体表面，转换成热能，大大提高了背板的温度，降低了太阳能背板的转换效率。

本发明所采用的技术方案如下：
一种高效率太阳能背板结构，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反光层，在所述反光层的表面设置波形凹凸结构，在所述波形凹凸结构的表面还覆盖弥散层，于所述PET基材的另一端通过粘结层连接耐候粘结层；所述弥散层采用丙烯酸树后涂料、聚氨酯涂料、有机硅树脂涂料、二氧化硅涂料、硅酸盐涂料中的任意一种。
本发明的有益效果如下：
本发明结构简单、使用方便，反光层及凹凸结构的布置可以提高本发明对光线的反射率，通过设置弥散层增加了光的散射，使可被太阳能背板吸收的光增多，从而提高了太阳能背板组件的能量转换效率。
