  • Patent number: 10340844
    Abstract: A light scattering-based solar concentrator (LSSC) uses high refractive index nanoparticles (NPs) as dopants to selectively scatter photons across the solar spectrum without spectroscopic conversion by different sized nanoparticles. The LSSCs are limited by a single parameter: the surface photon losses, which can be addressed by nanofabrication to implement anti-reflective and light trapping structures into LSSC designs. The LSSC design provides solar concentrator techniques for photovoltaic (PV) applications.

  • Patent number: 10315452
    Abstract: A forensic feature for a secure document comprises a base document layer and a covert material applied to the base document layer. The covert material includes a carrier and forensic material within the carrier. The forensic material includes a ratio of salts or oxides of metals, such as rare earth metals. The ratio is selected to correspond with a source of the document. The forensic material may be mixed into a coating or ink that is applied at predetermined locations on a secure document. The ratio is then measurable from metal ion signals of the salts or oxides. This ratio, or some metric derived from it, may be linked with information embedded elsewhere in the document to enable verification of the document. Another forensic document feature has a forensic metric that is measurable from a covert material in the document, and this forensic metric corresponds to a source of the document.

  • Patent number: RE47578
    Abstract: An organic light emitting diode (OLED) and a method of manufacturing the same. An auxiliary layer comprising a high density metallic compound and an emission layer are formed by a laser induced thermal imaging (LITI) process. The LITI process reduces manufacturing costs and time by eliminating the need for a mask patterning process. The metallic compound has a density of 2 g/cm3 or greater to promote adhesion and improve interfacial planarization. This results in improved luminance uniformity (i.e. luminance mura) between pixels within an OLED display device.
