  • Publication number: 20240235475
    Abstract: Photoluminescence and electroluminescence are essential characterization techniques for photovoltaics cells and modules. For electroluminescence, the main technical challenge is easily injecting current into the photovoltaic to cause luminescence. The technique described herein enables daylight electroluminescence imaging without the need for external power sources. For photoluminescence, characterization is performed on photovoltaic cells, modules, strings, and arrays in daylight and without temporary mounting of LED modulators. Instead, the modulation is performed using a permanent electronic module installed within the electric circuit on the DC side. This enables automation or triggering of modulation on demand, 100% inspection without changes in hardware configuration because the cells are never shaded and provides a path to high throughput imaging.

  • Publication number: 20240210786
    Abstract: The discovery of a clear correlation between the Anderson localization length and the dispersion properties of highly localized TALOF modes allowed us to demonstrate that the zero dispersion wavelength can be tuned over more than 300 nm within the same fiber by selected excitation of specific modes. This enabled apparatus and methods for generating tunable, multi-octave-spanning supercontinuum (SC) spectra in a bandwidth from 460 nm to 1750 nm. Associated applications are also presented.

  • Patent number: 11980865
    Abstract: A composition can be used to treat water containing nitrogen compounds and phosphorus compounds. The composition includes iron filings, clay particles, aluminum particles, and sand particles. The iron filings, clay particles, and aluminum particles act to remove nitrogen compounds and phosphorus compounds from water. Specifically, the clay particles attract the nitrogen compounds and the phosphorus compounds to be absorbed onto a surface of the iron filings and the clay particles. The aluminum particles react with the nitrogen compounds via an oxidation reaction to form ammonia compounds and react with the phosphorus compounds to produce aluminum phosphate. The relationship between the iron filings, clay particles, and aluminum particles remove nitrogen and phosphorus compounds from water and recover the compounds in usable forms, namely, ammonia and aluminum phosphate.
