Concentrator for use with photovoltaic devices includes a waveguide (2) incorporating quantum dots. The quantum dots red-shift the incident radiation to produce red-shifted radiation which is internally reflected within the waveguide (2). A photovoltaic device (10) converts the red-shifted radiation to electrical energy.

L'invention concerne un concentrateur destiné à s'utiliser avec des appareils photovoltaïques et comprenant un guide d'ondes (2) comportant des points quantiques. Les points quantiques décalent vers le rouge le rayonnement incident afin de produire un rayonnement décalé vers le rouge qui est reflété à l'intérieur du guide d'ondes (2). Un appareil (10) photovoltaïque convertit le rayonnement décalé vers le rouge en énergie électrique.
