Abstract
The utility model relates to a flexible-solar-cell high-reflection combination structure, comprising a base layer and a reflection layer. An ion implantation layer is arranged between the base layer and the reflection layer. The surface of the reflection layer is equipped with a protection layer. Through the formation of the ion implantation layer between the base layer and the reflection layer, the binding force of the reflection layer and base layer is increased. The protection layer isolates the reflection layer from peripheral atmosphere, guaranteeing the reflection performance and enhancing the stability and the durability of the high-reflection combination structure, which can be widely applied to flexible solar cells.
