一种光谱转换光伏组件
技术领域
本发明涉及太阳能电池组件技术领域，具体为一种光谱转换光伏组件。
背景技术
目前光伏产品在追求高的转换效率，即相同的面积下产生尽可能多的电力。晶体硅太阳能电池可以吸收并转化为电的光谱范围为300-1100nm，紫外光被前表面的玻璃与EVA吸收，难以利用，而红外光则因为晶体硅电池的禁带宽度，不能被电池吸收。如何将紫外光转化为晶体硅电池可以吸收的长波长光，提高了光的利用率，是本发明需要解决的问题。
发明内容
本发明的目的就是针对上述存在的问题而提供一种光谱转换光伏组件。本发明在玻璃表面设置紫外转化层，将紫外光转化为晶体硅电池可以吸收的长波长光，提高了光的利用率，而且紫外光被转化后，组件的封装材料则较少的受到紫外光的损害，进而增强了组件的户外可靠性。
本发明的一种光谱转换光伏组件技术方案为，该组件由上到下依次包括封装玻璃、EVA、电池片、EVA、背板，在封装玻璃上方设置一层紫外转换层。
所述的紫外转换层为紫外荧光粉使用THV(3M公司)涂覆于玻璃表面。
紫外转换层厚度为0.1-1cm。
进一步的，紫外转换层厚度为0.3-0.7cm。
优选的，紫外转换层厚度为0.5cm。
封装玻璃厚度1-4cm。
进一步的，封装玻璃厚度3-3.5cm。
优选的，封装玻璃厚度3.2cm。
本发明的一种光谱转换光伏组件有益效果为：本发明在玻璃表面设置紫外转化层，将紫外光转化为晶体硅电池可以吸收的长波长光，提高了光的利用率，而且紫外光被转化后，组件的封装材料则较少的受到紫外光的损害，进而增强了组件的户外可靠性。
