Description

高反射率太阳能背板
技术领域
本发明涉及太阳能组件领域，尤其涉及高反射率太阳能背板。
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，目前现有结构的太阳能背板性能不稳定，反射率、抗老化性能差，结构复杂导致加工复杂、使生产成本增加。
发明内容
本申请人针对上述现有问题，进行了研究改进，提供一种高反射率太阳能背板，其能实现太阳能背板的高反射率并具有出色的抗老化性能。
本发明所采用的技术方案如下：
一种高反射率太阳能背板，包括PET基材，于所述PET基材的一侧顺序通过增效膜层、粘结层粘接耐候层，于所述耐候层的上表面粘结平面反射层；所述PET基材的另一侧也通过粘结层连接粘接耐候粘结层。
作为上述技术方案的进一步改进：
所述平面反射层的厚度为50～1000微米。
所述增效膜层的厚度为40～160um。
所述平面反射层由聚丙烯酸加入片状二氧化钛及氧化锌制备形成。
所述耐候层的厚度为10～50微米。
所述耐候粘结层的厚度为40～60微米。
本发明的有益效果如下：

如图1所示，一种高反射率太阳能背板，包括PET基材3，于PET基材3的一侧顺序通过增效膜层5、粘结层2粘接耐候层1，于耐候层1的上表面粘结平面反射层6；PET基材3的另一侧也通过粘结层2连接粘接耐候粘结层4。平面反射层6的厚度为50～1000微米。增效膜层5的厚度为40～160um。平面反射层6由聚丙烯酸加入片状二氧化钛及氧化锌制备形成。耐候层1的厚度为10～50微米。耐候粘结层4的厚度为40～60微米。
本发明太阳能电池背板的耐候层材料为含氟耐候层，其具有成本低，环保性能好，其力学性能、粘结强度也比传统背板好，背板结构更为稳定，对整个太阳能支撑保护作用更加突出，本发明提供的太阳能电池背板明显优于现有背板，聚酯薄膜的设置提高了电气绝缘性、水气阻隔性，其耐湿热耐老化性能高，其具有寿命长，耐候性高、高反射率及出色的抗老化性能。本发明反射层的布置具有反射性能好、粘接效率好，平整性好的优点，增效膜层用于吸收20～500nm的紫外线光，其能转换利用现有电池片无法转化的光波，拓宽对太阳能电光谱吸收转化范围，使太阳能电池的光转化效率提高。
