    摘要: Disclosed are thermoplastic resin formulations for use as a light transmitting layer (e.g., encapsulant layer) in a photovoltaic module comprising: (a) a light transmitting thermoplastic resin, (b) at least one down conversion material that exhibits a maximum in incident radiation absorption in the range of 280 to 500 nm and a maximum in radiation emission at a relatively longer wavelength in the range of 400 to 900 nm and improves the efficiency of photovoltaic electric current generation in a photovoltaic module; and (c) a light stabilizer additive that transmits at least about 40 percent of the ultraviolet (UV) electromagnetic radiation having a wavelength in the range of from about 280 nm to about 380 nm. Also disclosed are sheet materials prepared from such resins and photovoltaic modules incorporating such sheet materials.

    摘要: There is provided an apparatus for monitoring the relative concentration of an analyte in a fluid stream, with such apparatus including a capillary tube for containing the flowing fluid, optics for directing a single beam of monochromatic light through the capillary tube to produce a diffraction pattern having a number of interference fringes. A translatable photodiode is provided to monitor a portion of one of the fringes passing through a light limiting slit, whereby a signal proportional to the concentration of the analyte in the fluid is produced based upon the varying intensity of the monitored fringe. The capillary tube is preferably provided as a fused silica member having an inner flow diameter of 100 micrometers or less.
