- the above three kinds of test pieces differ in the pore size of the nanostructure on the superparamagnetic layer, which is D1 (about ten nanometers) ⁇ D2 (about several tens of nanometers) ⁇ D3 (about hundreds of nanometers).
- the surface of the above three test pieces was irradiated with an ultraviolet laser, and the spectrum of the reflected light was measured. The results are shown in Fig. 8.
- the MnZnFe ferr i te/AAO/Sapphi re multilayer structure As shown in Fig. 8, in the reflected light spectrum, the three test pieces of Dl, D2 and D3 all obviously caused a red shift to the ultraviolet light.
- the D1 test piece with the smallest aperture of the nanostructure on the superparamagnetic layer has a peak of the reflected light spectrum at a wavelength of about 410 nm.
- the D2 test piece with the second largest aperture of the nanostructure on the superparamagnetic layer has a peak of reflected light at a wavelength of about 425 nm.
- the D3 test piece with the largest pore diameter of the nanostructure on the superparamagnetic layer has a peak of the reflected light spectrum at a wavelength of about 450 nm.
- the results in Figure 8 are again confirmed to be controllable through the process.
- the geometrical parameters of the nanostructures (holes or protrusions) on the superparamagnetic layer, such as the aperture (outer diameter), alignment, etc., can achieve the optical properties of the desired modulated light.
- a solar cell device uses a superparamagnetic layer to modulate light energy in a wavelength band that is not utilized in sunlight to a wavelength band that can be converted into electrical energy by a photovoltaic element.
- the conversion performance of the solar cell device is improved, and the heat converted by the unutilized light energy is also slowed down to cause adverse effects on the solar cell device.

Abstract
L'invention concerne un appareil de cellule solaire (1) ayant fonction de modulation de la lumière. L'appareil de cellule solaire (1) comprend un élément photovoltaïque (10) et une couche superparamagnétique (12). L'élément photovoltaïque (10) comprend une jonction p-n (102). La jonction p-n (102) est utilisée pour convertir en énergie électrique de l'énergie d'une première bande de longueurs d'onde de la lumière solaire. La couche superparamagnétique (12) est formée de manière à ce que la lumière solaire se transmet d'abord à travers la couche superparamagnétique, puis irradie la jonction p-n (102). Plus spécifiquement, lorsque la lumière solaire se transmet à travers la couche superparamagnétique (12), l'énergie d'une seconde bande de longueurs d'onde de la lumière solaire est modulée sur l'énergie de la première fréquence de longueur d'onde par la couche superparamagnétique (12).
