<p>The device has a Fresnel lens (10) provided on a thin reflective layer (11) and focusing sunlight incident on a determined surface on the reflective layer. The reflective layer contains pores, which are open in light focus for allowing a large portion of the sunlight to pass into a hollow space (13). The hollow space includes reflective walls (14) and contains photovoltaic elements (15), where total area of the photovoltaic elements is 50 percentage smaller than a surface of the usable incident sun light. Cooling ribs (19) are provided at a rear side of the hollow space. An independent claim is also included for a method for collecting sunlight.</p> |
