Abstract

L'invention concerne un dispositif servant à concentrer de la lumière incidente (L), en particulier la lumière solaire, comportant au moins un élément calotte ou miroir (10), en particulier de section transversale sphérique et/ou en particulier en forme de gouttière ou de cuvette, au moyen duquel la lumière incidente (L) peut être dirigée ou renvoyée ou déviée sur au moins un moyen d'absorption photovoltaïque (20), en particulier sur au moins un système de cellules solaires, par exemple sur au moins un panneau solaire ou au moins une rampe solaire. L'invention concerne également un procédé associé. L'invention vise à perfectionner ledit dispositif de sorte que les effets d'ombrage influent le moins possible, voire pas du tout sur la quantité de lumière incidente qui est convertie en énergie électrique. A cet effet, le moyen d'absorption (20) est disposé de manière asymétrique par rapport à l'élément calotte ou miroir (10), en particulier par rapport à l'axe de symétrie de l'élément calotte ou miroir (10), par exemple par rapport à l'axe central de l'élément calotte ou miroirs (10). En particulier, le moyen d'absorption (20) est disposé dans la zone excentrée ou latérale de l'élément calotte ou miroir (10).
