摘要： A photovoltaic module comprises at least one photovoltaic cell and one concentration optic device, to be illuminated by a light flux emitting at at least one illumination wavelength belonging to a band of wavelengths defined by a minimum wavelength and a maximum wavelength, the band of wavelengths being that of the solar radiation of the order of [380 nm-1600 nm]. The concentration optic device is a monolithic component and comprises at least one diffractive structure comprising subwavelength patterns, defined in a structured material; the patterns having at least one dimension less than or equal to the average illumination wavelength divided by the refractive index of the structured material; the patterns being separated from one another by subwavelength distances, defined between centres of adjacent patterns; the concentration optic device ensuring at least one focusing function and one diffraction function. A solar panel comprising the photovoltaic module is also provided.
