Abstract

Die Erfindung betrifft einen Solarkonzentrator (1) mit einem massiven Körper aus einem transparenten Material, der eine Lichteinkoppelfläche (2) und eine Lichtauskoppelfläche (3) umfasst, wobei der massive Körper zwischen der Lichteinkoppelfläche (2) und der Lichtauskoppelfläche (3) einen sich in Richtung der Lichtauskoppelfläche (3) verjüngenden Lichtleiterteil (4) umfasst, der zwischen der Lichteinkoppelfläche (2) und der Lichtauskoppelfläche (3) durch eine Lichtleiterteil-Oberfläche (5) begrenzt ist, und wobei die Lichtleiterteil-Oberfläche (5) mit einer stetigen ersten Ableitung in die Lichtauskoppelfläche (3) übergeht. Die Erfindung betrifft auch ein Verfahren zum Herstellen eines Solarkonzentrators (1), wobei das transparente Material zwischen Formen (10, 14) blankgepresst wird.
