Design for Optimal One-Dimensional Surface Profile of EVA on Solar Cell Modules

Abstract:

Ethylene Vinyl Acetate (EVA) as package material is widely used in solar cells modules. Conventionally, it is laminated on both sides of solar cells with a planar surface profile, which will lead to high reflectance when the light incident angle is larger than 60°. We proposed a 1-dimensional triangular surface profile of EVA on solar cell modules with base angle about 43°. The investigations show that a 9.9% efficiency improvement of solar cells can be obtained by reducing its surface reflectance.
