NOVELTY - The device for flexible protection of structural elements such as electronic elements and photovoltaic elements from environmental influences, comprises covering elements (2), which are impermeable to water vapor and oxygen, are embedded in a polymer layer and are arranged in up to two dimensions (length and width) in an overlapping manner, so that the flexible material composite is arbitrarily larger with limited size of the covering elements. The overlapping area (3) is selected, so that a diffusion path for the water vapor and oxygen is effectively extended.    USE - Device for flexible protection of structural elements such as electronic elements and photovoltaic elements from environmental influences.    ADVANTAGE - The device ensures flexible and effective protection of the structural elements from the environmental influences thus achieving long-term stable photovoltaic elements with improved breaking strength, flexible material properties, high mechanical stability and improved tensile strength.    DETAILED DESCRIPTION - The device for flexible protection of structural elements such as electronic elements and photovoltaic elements from environmental influences, comprises covering elements (2), which are impermeable to water vapor and oxygen, are embedded in a polymer layer and are arranged in up to two dimensions (length and width) in an overlapping manner, so that the flexible material composite is arbitrarily larger with limited size of the covering elements. The overlapping area (3) is selected, so that a diffusion path for the water vapor and oxygen is effectively extended such that the sensitive structural elements are effectively protected. The covering elements are made of glass that is a thin glass, and have thicknesses that allow the formation of flexible material composite. The thickness of the polymer layer is selected, so that the covering elements withstand the mechanical loads such as hail stroke. The polymer layer is made of different polymer layers (1a, 1b), where the embedded polymer layer is hot adhesive films or casting masses. The hot adhesive films are ethylene vinyl acetate film, thermoplastic polyurethane film, polyvinyl butyral film, silicone film or ionomer film. The covered polymer film is a weather-stable and UV-stable fluoropolymer film such as ethylene tetrafluoroethylene. The polymer layers and the covering elements are transparent.
