Abstract
(EN)
A photovoltaic device has a photovoltaic cell and a photon-conversion component. The photon-conversion component has a photon-conversion material in its composition. The photon-conversion material, while the photovoltaic device is in operation, converts photons in a spectral region including a first wavelength to photons in a spectral region including a second wavelength, the second wavelength being longer than the first wavelength. The photons having the second wavelength are at least one of less damaging to the photovoltaic cell than photons having the first wavelength or converted more efficiently to an electrical current than photons having the first wavelength.

Cette invention concerne un dispositif photovoltaïque comprenant une cellule photovoltaïque et un composant de conversion de photons. Le composant de conversion de photons comprend, dans sa composition, un matériau de conversion de photons qui, lorsque le dispositif photovoltaique fonctionne, convertit les photons dans une région spectrale comprenant une première longueur d'onde en photons dans une région spectrale comprenant une deuxième longueur d'onde, la deuxième longueur d'onde étant plus longue que la première longueur d'onde. Les photons présentant la deuxième longueur d'onde endommagent moins la cellule photovoltaïque que les photons présentant la première longueur d'onde et/ou sont convertis plus efficacement en courant électrique que les photons présentant la première longueur d'onde.
