Abstract
Disclosed are encapsulation materials including an 80 to 99.5 weight percentage (wt %) of ethylene vinyl acetate copolymers (EVA) and a 0.5 to 20 weight percentage(wt %) of a photoluminescent polymer, wherein the EVA and the photoluminescent polymers are evenly blended. The encapsulation materials can be applied to packaging solar cells, and the encapsulating structure may protect the EVA from UV damage and enhance light utilization efficiency of the solar cell.
