Description

一种具有频谱转换功能的光伏组件
技术领域
本发明涉及一种光伏组件,具体涉及一种具有频谱转换功能的光伏组件。
背景技术
光伏发电是直接将光能转化为电能的能源利用方式,其利用的发电装置基本单元为太阳电池,将太阳电池串联层压制得组件,排列组成阵列才可以保证功率输出和持续使用。现有光伏组件存在诸多不足,其中一个重要方面就是不能充分的利用太阳光谱,波长大于1100nm的红外光不能够被电池吸收利用,造成能量损失;波长较短的紫外线只能放出一个光子,形成一个点子空穴对,多余的能量会形成热弛豫,这将造成较低的光电转换效率和性能衰减。
发明内容
本发明所要解决的技术问题是提供一种具有频谱转换功能的光伏组件,应用了下转换发光透明玻璃,有效增强电池的短波响应,有效阻挡紫外线,减缓EVA薄膜的老化。
本发明解决技术问题所采用的技术方案是:一种具有频谱转换功能的光伏组件,包括由若干电池片排列的电池阵列,所述电池阵列的上下均覆盖一层EVA薄膜,所述电池阵列的受光面外层为下转换发光透明玻璃,所述电池阵列的背光面外层为TPT背板。
作为一种优选,所述下转换发光透明玻璃为掺Sm3+和Sm2+的氟化物玻璃,能有效地将280-500nm的紫外光转换为350-1100nm的光;其透光率T>95%。
本发明在光伏组件结构中引入具有下转换功能的玻璃,可以使光伏组件更好地吸收不易被电池利用的紫外光和红外光。所谓下转换,即在高能量光子激励下,使得两个离子都从激发态跃迁回基态发出两个可见光子,吸收一个紫外光子可以放出两个可见光子,理论上量子效率可超越100%,能更有效的吸收紫外光,提高对太阳光的利用效率,还可以减少紫外光对电池的热弛豫和降低对组件EVA薄膜的损害,从而提高光伏组件性能。
本发明将下转换发光透明玻璃、EVA薄膜、电池阵列和TPT背板按序层叠,经由层压、装框和固化工序制备而成。
本发明的有益效果是: 在光伏组件中应用下转换发光透明玻璃,有效增强电池的短波响应,还可以有效阻挡紫外线,减缓EVA薄膜的老化。
