摘要
目前光伏建筑一体化(BIPV)及各类轻质化光伏都偏向与轻和柔,但传统光伏组件封装使用的玻璃制成组件重量较重,诸如屋顶或者户外会存在一定的便携和安全问题。本文通过甲基丙烯酸甲酯(MMA)树脂涂覆玻纤交联的方法制备了轻质光伏组件封装材料,采用高温高湿老化机(双85)、耐紫外老化机(UV)、紫外分光光度计、万能材料试验机、耐溶剂测试分别表征了封装材料的耐老化、耐紫外、拉伸强度、弯曲模量、耐溶剂等性能。研究结果表明,在树脂含量60%,厚度0.3mm、引发剂含量1%时,经过300kW·h紫外辐照,双85测试3000h和耐溶剂测试后,封装材料透光率保持在89%,拉伸强度433MPa,水透1.2g/d·m^(2)。
Currently,building-integrated photovoltaic(BIPV)and various types of lightweight photovoltaic are inclined to be light and flexible,but the traditional PV module encapsulation using glass made modules are heavy in weight,such as photovoltaic modules used on the roof or outdoors will have certain portability and safety problems.In this paper,lightweight photovoltaic module encapsulation materials were prepared by cross-linking glass fibers coated with methyl methacrylate(MMA)resin.The encapsulation materials were characterised for ageing resistance,UV resistance,tensile strength,bending modulus and solvent resistance using high temperature and high humidity ageing machine(double 85),UV resistance ageing machine(UV),UV spectrophotometer,universal material testing machine and solvent resistance tests.The results show that after 300 kW·h UV irradiation,3000 h of double 85 test and solvent resistance test at 60%resin content,0.3 mm thickness,and 1%initiator content,the encapsulation material maintains 89%light transmission,433 MPa tensile strength,and 1.2 g/d/m^(2) water permeability.
