  • Patent number: 11437532
    Abstract: The production process according to the invention consists of a nanometric scale transformation of the crystalline silicon in a hybrid arrangement buried within the crystal lattice of a silicon wafer, to improve the efficiency of the conversion of light into electricity, by means of hot electrons. All the parameters, procedures and steps involved in manufacturing giant photoconversion cells have been tested and validated separately, by producing twenty series of test devices. An example of the technology consists of manufacturing a conventional crystalline silicon photovoltaic cell with a single collection junction and completing the device thus obtained by an amorphizing ion implantation followed by a post-implantation thermal treatment.

  • Patent number: 10971642
    Abstract: The solar photovoltaic photoconverter unit (1) comprises a light processing opto-photonic platform (2) realized by at least one transparent substrate (8) is having on, at least one, of its faces a digital diffractive grating constituted by slanted ribs (11) that are modulated to harvest a maximum of solar light at any angle of incidence to split it into several spectral sub-bands, to guide and to concentrate individually every one of these spectral sub-band, toward a separate output of the opto-photonic platform (2) for allowing its exploitation by a light-to-electricity conversion unit (3) that will have by optimization a grate overall conversion efficiency. The opto-photonic platform (2) also includes photonic converters (13) and (14) converting ultraviolet light into visible light and also infrared light in visible light for a better exploitation of the energy present in the solar light and so increasing the light to electricity conversion.

  • Patent number: 10886422
    Abstract: This invention concerns a grouped nanostructured unit system forming a metamaterial within the silicon and the manufacturing process to arrange them therein in an optimal manner. The nanostructured units are grouped and conditioned in an optimal arrangement inside the silicon material. The process comprises the modification of the elementary crystal unit together with the stress field, the electric field and a heavy impurity doping in order to form a superlattice of nanostructured units grouped in an optimal arrangement so as to improve the efficiency of the light-to-electricity conversion by means of efficient use of the kinetic energy of hot electrons and efficient collection of all electrons generated within the converter.

  • Patent number: 10020408
    Abstract: Architecture of the light-to-electricity converter characterized in that the system of amorphized nanograins, preferentially nanograins of amorphized silicon, of any shape are optimally spread within the crystalline host material, preferentially crystalline silicon that are wrapped around with a metamaterial seg-matter nanolayer, characterized by secondary generation centers, called segtons, that are conditioned around divacancies and disposed entirely or only partly within the volume of the emitter, this volume being limited at each end by a nanomembrane assuming the appropriate exploitation of the lower-energy secondary generation through the giant photoconversion involving hot electrons, segtons, and seg-matter.

  • Patent number: 9722121
    Abstract: The invention bears on elementary nanoscale units nanostructured-formed inside a silicon material and the manufacturing process to implement them. Each elementary nanoscale unit is created by means of a limited displacement of two Si atoms outside a crystal elementary unit. A localized nanoscale transformation of the crystalline matter gets an unusual functionality by focusing in it a specific physical effect as is a highly useful additional set of electron energy levels that is optimized for the solar spectrum conversion to electricity. An adjusted energy set allows a low-energy secondary electron generation in a semiconductor, preferentially silicon, material for use especially in very-high efficiency all-silicon light-to-electricity converters. The manufacturing process to create such transformations in a semiconductor material bases on a local energy deposition like ion implantation or electron (?,X) beam irradiation and suitable thermal treatment and is industrially easily available.
