NOVELTY - The structure (202) has a carrier element (204) provided with a surface relief pattern comprising surface relief forms (208) and predetermined optical function relative to incident light. The carrier element comprises optically transparent material enabling light transmission. The carrier element is laminated with another carrier element (206) such that the surface relief pattern is embedded within the structure and related, optically functional cavities are formed at an interface of the carrier elements.    USE - Integrated laminate structure for use in a solar cell structure (claimed) utilized with an indicative element e.g. poster, sign such as traffic sign and luminous tag, and plate, in a street light. Can also be used for an integrated electronic device, semiconductor, biomedical system, tribological system, window i.e. window lighting, green house illumination, advertising, security application, automotive and generally vehicle industry, halogen replacements and public illumination.    ADVANTAGE - The structure's laminated elements are securely joined together by lamination, so that undesired gaps such as air gaps are avoided by the surface relief pattern, thus reducing manufacturing cost and complexity of the structure. The structure is protected from external impulses and contamination, thus extending life of the structure. The structure utilizes an integrated reflector with micro-cavities to maintain sunlight longer inside the structure, thus improving energy absorption, and hence improving efficiency of the solar cell. The structure is designed such that a degree of flexibility and bendability is achieved with predetermined bend radius without material breakage. The structure contains small flat portions such as contact surfaces on laminate junction areas to enhance adhesion of associate laminate layers and to obtain desired light propagation. The structure allows a light source such as LED, to be collimated along two-dimensional horizontal direction, thus making a coupling pattern to be simple and efficient.    DETAILED DESCRIPTION - The carrier elements comprises a material selected from a group consisting of plastic, elastomer, polymer, glass, semiconductor, silicon, adhesive, resin and ceramic material. INDEPENDENT CLAIMS are also included for the following:    (1) a solar cell structure comprising a semiconductor material-containing element    (2) a method for constructing an integrated structure for optical applications in solar technology.
