DEVICE FOR COUPLING THE LIGHT OPTIMALLY TO A SOLAR CELL OF INTERMEDIATE BAND PERFORMED BY QUANTIC POINTS.

摘要

Device for coupling the light to an intermediate band solar cell (8) made by quantum dots that also concentrates the light. The energy of the light emitted by the luminescent material (2) is chosen to produce transitions between the valence band and the conduction band of the cell. The pigments of the luminescent material (6) are chosen so that the emitted photons produce transitions from the valence band to the intermediate band and from this to the conduction band. The photonic crystals (1) and (3) prevent the light emitted by the layer (2) from escaping. The photonic crystals (4) and (5) prevent the light emitted by the material (6) from escaping. The device also includes a reflector (7) and a support (9).
