Opto-electronic unit composed of an opto-photonic platform

An opto-electronic unit to be used as a photovoltaic solar sensor, comprising:

• an opto-photonic platform adapted to be exposed to solar radiation and comprising at least one photonic converter and at least one photonic diffraction grating incorporated therein comprising a plurality of diffractive structures, wherein the opto-photonic platform is configured to specifically output radiation wavelengths of spectral sub-bands of the visible range having predetermined widths,
• wherein the plurality of diffractive structures are slanted relative to a normal of a main plane of the photonic diffraction grating so that respective surfaces of the plurality of diffractive structures are oriented toward the main plane of the photonic diffraction grating,
• wherein at least one of the plurality of diffractive structures has at least one selected from the group consisting of a different height, a different thickness, a different slant angle, a different position, a different spacing, and a different pitch than at least one other of the plurality of diffractive structures,
• wherein the plurality of diffractive structures comprise slanted ribs or slanted fringes having height dimensions within a range of from 0.3 to 3 nanometers, and spacings between two adjacent ribs or fringes are within a range of from 100 to 600 nanometers,
• a light-to-electricity conversion unit operatively associated with said opto-photonic platform comprising a plurality of light-to-electricity converters each having an exposure surface upon which said specifically outputted spectral sub-bands of the visible range, outputted from said opto-photonic platform, are respectively received as incident light flux so as to produce electricity.
