Title
(EN) SOLAR WAVEGUIDE CONCENTRATOR
(FR) CONCENTRATEUR DE GUIDE D'ONDE SOLAIRE
Abstract
(EN) A photovoltaic device including a waveguide layer having a first surface for receiving light, a second surface opposite the first surface for reflecting light, and at least one edge surface generally perpendicular to the first and second surfaces for emitting light; and a light collector layer adjacent to the waveguide layer that includes a first surface for receiving light, and a second surface for emitting light, wherein the second surface of the light collector layer includes a plurality of optical elements having a three-dimensional tapered shape with a top surface that is larger than a bottom surface, and wherein the bottom surface of each of the optical elements is in optical contact with the first surface of the waveguide layer. At least one edge surface of the waveguide layer is optically coupled to at least one photovoltaic cell.
(FR) L'invention concerne un dispositif photovoltaïque comprenant une couche guide d'onde avec une première surface servant à recevoir de la lumière, une deuxième surface opposée à la première surface servant à réfléchir la lumière, et au moins une surface bord généralement perpendiculaire aux première et deuxième surfaces servant à émettre de la lumière ; et une couche collecteur de lumière adjacente à la couche guide d'onde qui comprend une première surface servant à recevoir de la lumière, et une deuxième surface servant à émettre de la lumière, la deuxième surface de la couche collecteur de lumière comprenant une pluralité d'éléments optiques avec une forme tronconique tridimensionnelle avec une surface supérieure qui est plus grande qu'une surface inférieure, et la surface inférieure de chacun des éléments optiques étant en contact optique avec la première surface de la couche guide d'onde. Au moins une surface bord de la couche guide d'onde est couplée optiquement avec au moins une cellule photovoltaïque.
