摘　　要：根据晶硅电池的光学、电学参数改善组件封装材料相关性能，使晶硅电池封装功率损失显著降低。根据不同电池的量子效率（EQE），调节镀膜玻璃的透过率分布曲线，使两者实现最佳匹配，从而提高组件光电转换效率。前端封装材料使用紫外高透乙烯．醋酸乙烯共聚物（EVA），背面封装材料使用紫外截止EVA，既可提高效率，又能保证组件的抗紫外性能，其平均功率的增益为1．0％～1．5％。According to optical and electrical parameters of crystalline silicon solar cell, module encapsulation materials, such as glass and ethylene-vinyl acetate copolymer （EVA） were improved to reduce power loss of encapsulation significantly. Firstly, the transmittance distribution curve of AR-coating glass was regulated according to the external quantum efficiencies of different solar cells, making them the best match to increase power output of solar PV modules. Secondly, ultra-violet （UV）-transparent EVA was adopted in the front of solar cells and common EVA was used at the rear side, which could increase power output of PV modules by 1.0 to 1.5 percent and protect back sheet from UV harm.
