高透光封装胶膜技术综述

A research review on the encapsulants with high transmittance character

封装材料的透光率直接影响到电池组件的发电效率。从降低光学损失、提高太阳光利用率的观点出发,综述和评论了高透光乙烯-醋酸乙烯(EVA)共聚物封装胶膜改性的研究方法并对各种改性方法进行风险评估,为太阳能组件提高转换效率、降低成本提供解决方案。

The efficiency of photovoltaic （PV） of modules are significantly aitected by the transparency oi encap- sulants. From the viewpoint of decreasing of optical loss and increasing of utilization rate of sunlight, the pres- ent paper reviewed and evaluated the reported methods of modifying the ethylene-vinyl acetate （EVA） copoly- mer encapsulant with high transparency character, as well as the risk assessment on modified methods. This re- view would provide the solution to increase transition efficiency and decrease costs of PV.
