  • Patent number: 10840403
    Abstract: The light conversion efficiency of a solar cell (10) is enhanced by using an optical downshifting layer (30) in cooperation with a photovoltaic material (22). The optical downshifting layer converts photons (50) having wavelengths in a supplemental light absorption spectrum into photons (52) having a wavelength in the primary light absorption spectrum of the photovoltaic material. The cost effectiveness and efficiency of solar cells platforms (20) can be increased by relaxing the range of the primary light absorption spectrum of the photovoltaic material. The optical downshifting layer can be applied as a low cost solution processed film composed of highly absorbing and emissive quantum dot heterostructure nanomaterial embedded in an inert matrix to improve the short wavelength response of the photovoltaic material. The enhanced efficiency provided by the optical downshifting layer permits advantageous modifications to the solar cell platform that enhances its efficiency as well.

    Abstract: Among other things, an imaging sensor includes a two-dimensional array of photosensitive elements and a surface to receive a sample within a near-field distance of the photosensitive elements. Electronics classify microbeads in the sample as belonging to different classes based on the effects of different absorption spectra of the different classes of microbeads on light received at the surface. In some examples, the number of different distinguishable classes of microbeads can be very large based on combinations of the effects on light received at the surface of the different absorption spectra together, spatial arrangements of colorants in the microbeads that impart the different absorption spectra, different sizes of microbeads, and different shapes of microbeads, among other things.

  • Patent number: 9005760
    Abstract: To provide a process for producing a phosphorescent body which allows efficient production of a granule-shaped phosphorescent body with a simple facility and a phosphorescent body produced by the process, and a nail stone including the phosphorescent body. In a process for producing a phosphorescent body containing at least a phosphorescent material and a glass material, at least the phosphorescent material and the glass material are mixed to give a paste mixture 2. A plurality of layers of the mixture 2 are stacked to form a granule-shaped laminate 3. The laminate 3 is sintered so that the laminate 3 is melted and shaped by the action of the surface tension of the melted laminate 3.
