摘要
Photovoltaic modules - device (1) for the direct conversion of solar energy into electrical energy comprising a two-stage from several elements which are concentrator optical system, at least one solar cell (40) as well as a heat sink (50), wherein the materials of the elements of the concentrator optical system are matched to one another so that the concentrator optical system the transmission of sunlight with wavelengths & = 350 nm by at least 50% is reduced, wherein the concentrator optical system a cover plate (10), primary optics (20) and a secondary optics (30), by means of the optical systems (20, 30), a two-stage concentration of the sunlight is carried out; andat least one of the components, selected from the group consisting of cover plate (10), primary optics (20), secondary optics (30) and coatings (11, 12, 31, 32, 33) or more of these components at least one radiation absorber contains or comprises, wherein the at least one secondary optics (30) formed as a hollow body is reflective secondary optics; andthe reflective secondary optics at least in some areas an inner coating (33), consisting of tiox -, - snox or znox - cover layers on a carrier layer or a carrier substrate is composed of silver or aluminum.
