Description

一种单层层状光伏组件
技术领域
本发明涉及一种单层层状光伏组件，属于光伏太阳能技术领域。
背景技术
太阳能的利用越来越普及，而太阳能光伏系统是一种暴露在阳光下便会产生直流电的发电装置，光伏板组件可以制成各异的形状，且光伏板可相互连接以便获得更多的电力。
光伏系统的系统电压存在对电池组持续的电位诱发衰减效应，基于丝网印刷的晶体硅电池通过封装材料对光伏组边框相成的回路导致的漏电流，被认为是引发上述效应的主要原因。传统的光伏组件在高温高湿环境中发生的功率衰减较大，其严重影响到光伏组的质量及性能。
另外，由于透明玻璃层及金属框架的成本较高，且重量较大，使得光伏系统的成本较高，其重量无法适用于安装在屋顶及建筑幕墙上。
发明内容
本发明的目的是解决上述现有技术的不足，提供一种单层层状光伏组件。
为了达到上述目的，本发明所采用的技术方案为：
一种单层层状光伏组件，包括透明盖板、背板及夹设于所述透明盖板与背板之间的太阳能电池片，所述透明盖板与太阳能电池片之间具有第一封胶层，所述背板与太阳能电池片之间具有第二封胶层，
所述背板包括乙烯-醋酸乙烯共聚物层、对苯二甲酸乙二酯层、含氟层及铝材加固层，
所述乙烯-醋酸乙烯共聚物层与第二封胶层相邻，乙烯-醋酸乙烯共聚物层与对苯二甲酸乙二酯层相邻，对苯二甲酸乙二酯层与含氟层相邻，含氟层与铝材加固层相邻。
进一步地，所述透明盖板为氟塑料透明盖板。
进一步地，所述氟塑料至少包括乙烯一三氟氯乙烯共聚物、聚偏氟乙烯。
进一步地，所述铝材加固层为网格状镂空铝材加固层。
进一步地，所述铝材加固层的外侧具有便于一种单层层状光伏组件安装的安装机构，所述安装机构至少包括螺杆、凸起滑轨、卡扣件。
本发明的有益效果主要体现在：
1.背板水汽透过率低，结构强度大，重量轻，减轻了光伏组件的整体重量，使其能安装在屋顶及建筑物幕墙上；
2.太阳能电池片两侧具有封胶层，封胶层具有高体积电阻率的特点，在高温高湿环境中不会引发功率衰减，保障了光伏组件的输出功率和发电效果。
附图说明
图1是本发明一种单层层状光伏组件的结构示意图。
具体实施方式
本发明提供一种单层层状光伏组件，以下结合附图对本发明技术方案进行详细描述，以使其更易于理解和掌握。
如图1所示，一种单层层状光伏组件，包括透明盖板1、背板2及夹设于透明盖板1与背板2之间的太阳能电池片3，透明盖板1与太阳能电池片3之间具有第一封胶层4，背板2与太阳能电池片3之间具有第二封胶层5，背板2包括乙烯-醋酸乙烯共聚物层6、对苯二甲酸乙二酯层7、含氟层8及铝材加固层9，其中，乙烯-醋酸乙烯共聚物层6与第二封胶层5相邻，乙烯-醋酸乙烯共聚物层6与对苯二甲酸乙二酯层7相邻，对苯二甲酸乙二酯层7与含氟层8相邻，含氟层8与铝材加固层9相邻。
其中，透明盖板为氟塑料透明盖板，进一步降低了光伏组件的重量及成本。氟塑料至少包括乙烯一三氟氯乙烯共聚物、聚偏氟乙烯。
优化本方案，铝材加固层9为网格状镂空铝材加固层，结构强度高，重量轻。铝材加固层的外侧具有便于层状光伏组件安装的安装机构，安装机构至少包括螺杆、凸起滑轨、卡扣件。方便光伏组件的安装于支架、屋顶及建筑幕墙上。
