Abstract: The invention relates to a solar module having at least one solar cell, which is arranged between a front cover and a rear cover, and the front cover enables the passage of light to the solar cell. The solar module includes a rear cover having an at least two-layer, halogen-free coextrudate element which has a first thermoplastic layer facing the solar cell and a second thermoplastic layer facing away from the solar cell. The first thermoplastic layer includes a first filling material, which has a reflectivity that is higher than the reflectivity of the thermoplastic of the first thermoplastic layer, and the second thermoplastic layer includes a second filling material which has a higher thermal conductivity than the thermoplastic of the second thermoplastic layer.
