NOVELTY - The composite material useful in a solar cell (30), comprises multiple layers. The layers are laminated and connected with each other, and comprise a highly transparent resin adhesive layer (10) and an enhanced layer (20) for enhancing an intensity of the highly transparent resin adhesive layer. The solar cell is embedded in the highly transparent resin adhesive layer or embedded on a face part of a bottom layer. The enhanced layer comprises a common resin adhesive layer (21) and a carbon fiber layer (22).    USE - The composite material is useful in a solar cell.    ADVANTAGE - The composite material can be effectively, economically and rapidly manufactured with light weight, high intensity and improved self-lubricating property and creep and wear resistances.    DETAILED DESCRIPTION - The composite material useful in a solar cell (30), comprises multiple layers. The layers are laminated and connected with each other, and comprise a highly transparent resin adhesive layer (10) and an enhanced layer (20) for enhancing an intensity of the highly transparent resin adhesive layer. The solar cell is embedded in the highly transparent resin adhesive layer or embedded on a face part of a bottom layer. The enhanced layer comprises a common resin adhesive layer (21) and a carbon fiber layer (22). The carbon fiber layer is clamped between the common resin adhesive layer and the highly transparent resin adhesive layer and connected with the resin adhesive layers in a laminated manner. The solar cell is a crystalline silicon cell or a film cell. The film cell is embedded in the highly transparent resin adhesive layer. A light-receiving surface of the cells is arranged in parallel with a surface of the highly transparent resin adhesive layer. An INDEPENDENT CLAIM is included for a method for manufacturing a composite material.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a composite material.
