Description

提高发电效率的太阳能光伏板制作方法及太阳能光伏板 技术领域
本申请涉及由红外线辐射、可见光或紫外光转换产生电能，如使用光伏，具体涉及提高发电效率的太阳能光伏板制作方法及太阳能光伏板。
 背景技术
太阳能光伏板是通过光电效应或者光化学效应直接把光能转化成电能的装置，太阳能光伏板被光照到即可输出电压及电流，在这个过程中也有部分光能转化为热能，使光伏板发热。
光伏板是光伏电池组件的主体材料，光伏板通常采用铝框作为边框进行安装，铝框在太阳光的照射下，其温度会上升至超过光伏板本体的温度，尤其是在炎热的夏季，铝框的温度可能会高至85℃以上，光伏板的温度会高至65℃以上，由于铝框温度高于光伏板，光伏板的热量无法通过铝框散发出去，铝框反而会将热量传递给光伏板。
光伏板的最佳发电温度为25℃左右，光伏板的温度每升高一度，其发电效率大约下降0.4%，因此，目前现有的太阳能光伏板的铝框会在高温天气影响光伏板本体的发电效率。
