摘　　要：p-PERC+、n-PERT等结构的高效太阳电池的转换效率持续提升,双面化的结构设计在各类高效太阳电池和光伏组件中得以规模化普及应用。双面发电技术大幅降低了度电成本,可双面发电的光伏组件已经成为行业发展的大趋势。对于双面光伏组件的PID问题,可使用抗PID的增强型POE胶膜封装来解决,背面封装主要是使用玻璃或透明背板材料,但背面封装材料的长期可靠性仍需要进行验证。对比分析了透明PVF薄膜、PVDF薄膜、超耐候氟涂层膜等氟保护层材料的优劣,对耐紫外、耐湿热、UV+DH同步老化等性能进行对比,选择出性能更可靠的原材料及透明背板材料,并提供了高可靠性的透明背板封装解决方案。As the efficiency of high-efficiency solar cells with p-PERC+,n-PERT and other structures continues to increase,the bifacial PV modules are widely used due to the significant reduction of LCOE.The PID problem of bifacial PV module has been solved by using a anti-PID enhanced POE film.However,in addition to using glass for a backsheet material,if a transparent plastic material is used,the long-term reliability still needs to be verified.In this paper,the advantages and disadvantages of transparent PVF film,PVDF film,fluorine coating film and other raw materials are compared and analyzed.From the performance comparison of UV resistance,humidity resistance,UV+DH aging and other properties,the more reliable transparent backsheet to provide a highly reliable transparent backside packaging solution can be selected.
