Abstract
The present invention relates to a photovoltaic solar module, a process for the preparation thereof, and a device for generating electric energy employing such a solar module. The photovoltaic solar module has a wholly or partly surrounding frame of polyurethane which is characterized in that said frame has an elongation at break of at least 50%, a modulus of elasticity of at least 30 N/mmand a coefficient of thermal expansion of up to α=80×10/K, the modulus of elasticity and the coefficient of thermal expansion each being measured parallel to the edges of the module.
