La invención relaciona a un dispositivo para la luz del acoplamiento a una célula solar intermedia de la banda (8) hecha de puntos del quántum, que también concentra la luz. Las energías del luminescente el material luminiscente (2) se seleccionan por ejemplo para producir transiciones entre la banda de la valencia y la banda de conducción de la célula. Los pigmentos de los 6) son del material luminiscente (seleccionaron tales que los fotones emitidos producen transiciones de la banda de la valencia a la banda intermedia y de la banda intermedia a la banda de conducción. Los cristales 1 y 3 de Photonic evitan el luz emitido por la capa (2) de escapar, cristales photonic 4 de los ratos y 5 evitan el luz emitido por el material de tipo (6) de escapar. El dispositivo también incluye un reflector (7) y un elemento de soporte (9).
The invention relates to a device for coupling light to an intermediate band solar cell (8) made from quantum dots, which also concentrates the light. The energy of the light emitting the luminescent material (2) is selected such as to produce transitions between the valence band and the conduction band of the cell. The pigments of the luminescent material (6) are selected such that the emitted photons produce transitions from the valence band to the intermediate band and from the intermediate band to the conduction band. Photonic crystals 1 and 3 prevent the light emitted by the layer (2) from escaping, while photonic crystals 4 and 5 prevent the light emitted by the material (6) from escaping. The device also includes a reflector (7) and a supporting element (9).
