  • ANTI-REFLECTION WITH INTERCONNECTED STRUCTURES
    Publication number: 20230341761
    Abstract: An anti-reflective article includes a substrate including a surface and a bulk, and an arrangement of anti-reflective nanostructures along the surface of the substrate, each anti-reflective nanostructure of the arrangement of anti-reflective nanostructures being supported by the bulk of the substrate, each anti-reflective nanostructure of the arrangement of anti-reflective nanostructure tapering from the bulk of the substrate to define a respective peak. At least some of the anti-reflective nanostructures of the arrangement of anti-reflective nanostructures are linked with an adjacent anti-reflective nanostructure of the arrangement of anti-reflective nanostructures via a respective interconnection. The respective interconnections are in addition to the bulk of the substrate supporting the anti-reflective nanostructures. The respective interconnections are disposed at or above a midpoint between the peaks of the anti-reflective nanostructures and the bulk of the substrate.

  • Solar spectrum sensor for determining value of solar spectrum based on determined average photon energy
    Patent number: 11002597
    Abstract: A solar spectrum sensor, a consumer device and a method for determining an ambient solar spectrum. The solar spectrum sensor comprises a sensor unit configured for generating respective photo current outputs responsive to different parts of the solar spectrum; a measurement unit configured for measuring the respective photo current outputs from the sensor unit; and a processing unit for determining an average photon energy, APE, value of the solar spectrum from the measured photo current outputs and for determining the solar spectrum based on the determined APE.
