Abstract
本发明提供了一种防眩光双玻光伏组件,它包括双玻光伏组件本体,在双玻光伏组件本体的吸光表面贴有一层ETFE膜,该ETFE膜具有防眩光凹凸结构。本发明针对防眩光特点进行设计,当入射光线进入陷光结构的ETFE膜后,反射光到膜表面再入射到膜中,入射光到达膜与玻璃界面时一部分入射,一部分反射,反射的那部分又进行反射和折射,该结构同时具有透光和防眩光的功能,同时增加了光的透过率,提高了组件转化效率。电池片与组件面积比例的设计使防眩光双玻光伏组件达到建筑透光性的要求,又满足了一定的发电量需求。
Description
技术领域
本发明涉及光伏发电,特别涉及一种防眩光双玻光伏组件。
背景技术
光伏建筑一体化,是应用太阳能发电的一种新概念,就是将太阳能光伏发电阵列安装在建筑物的维护结构外表面来提供电力,其中光伏阵列与建筑的结合是一种常用的形式,特别是与玻璃幕墙的结合。
目前最常见的光伏玻璃幕墙组件是将太阳能电池片密封在双层钢化玻璃中,实现将太阳能转化为电能的生态建材,集发电、隔热、隔音、安全、装饰于一身,但是这种传统的光伏玻璃幕墙组件还存在光污染问题,对于公路、铁路、机场等严格要求防眩光的环境并不适用。
发明内容
本发明的第一个目的是提供一种防眩光双玻光伏组件,使其具有良好的防眩光功能。
本发明的第二个目的是设计有质地的凹凸纹理,使得光伏组件具有陷光效果。
本发明的第三个目的是使防眩光双玻光伏组件即要达到建筑透光性的要求,又要满足一定的发电量需求。
为了达到上述目的,本发明采用了以下技术方案:一种防眩光双玻光伏组件,包括双玻光伏组件本体,在双玻光伏组件本体的吸光表面贴有一层ETFE膜,所述ETFE膜具有防眩光凹凸结构。
所述ETFE膜通过EVA和双玻光伏组件本体的外层玻璃粘结。
所述防眩光凹凸结构包括多个排成阵列的四面锥斗形凹槽,凹槽的深度为0.25mm,凹槽四面的锥度为45度。
所述双玻光伏组件本体中,光伏电池片的总面积与组件总面积之比<90%。
为了使光伏组件有陷光效果,层压时在ETFE膜上预先放置网格纸,网格纸的外形与ETFE膜所需凹凸结构相匹配。在防眩光光伏组件设计中,光伏电池片总面积与组件总面积之比<90%,保证能够为建筑物提供足够的光线照明,满足建筑采光的要求,并能够达到较高的转化效率。
本发明防眩光双玻光伏组件,针对防眩光特点进行设计,当入射光线进入具有防眩光凹凸结构的ETFE膜后,反射光到膜表面再入射到膜中,入射光到达膜与玻璃界面时一部分入射,一部分反射,反射的那部分又进行反射和折射,该结构同时具有透光和防眩光功能,同时增加了透过率,提高了组件转化效率。电池片与组件的面积比例使防眩光双玻光伏组件达到建筑透光性的要求,又满足了一定的发电量需求。
