A near infrared (NIR) wideband reflector coating designed to start reflecting solar energy wavelengths from at least 1.2 microns in a typical geosynchronous earth orbit or medium earth orbit satellite and from at least 1.3 microns in a typical low earth orbit satellite. Also, the (NIR) wideband...
The present invention relates to a near-infrared heater device for photovoltaic power generation, which includes: a lower body formed in a case, installed therein with a blowing fan, and formed on an upper surface portion thereof with a plurality of perforated air outlets; an upper body formed...
Spin-allowed Fe2+ absorption bands occur in the visible and near-infrared diffuse reflectance spectra of most pyroxenes. The wavelengths of the bands centered near 1 m and 2 m vary as functions of pyroxene composition, making possible mineralogical and chemical deductions based on spectral reflectanc...
Herein, we developed a near-invisible solar cell through a precise control of the contact barrier between an indium tin oxide (ITO) electrode and a monolayer tungsten disulfide (WS2), grown by chemical vapor deposition (CVD). The contact barrier between WS2and ITO was controlled by coating vari...
A near-infrared phosphor, SrSiO:Ce,Yb, is developed as a potential solar spectral converter for Si solar cells. The diffuse reflection, photoluminescence excitation, and emission spectra at room temperature and at 3 K were investigated. These results show that the SrSiO:Ce,Ybphosphor has broadba...
Wu's team used ytterbium-doped nanocrystals to make the new LSC based on the concept of quantum cutting, or cutting one photon into two while conserving the total energy. The new materials emit two near-infrared photons after absorbing one blue photon, achieving an internal optical efficiency of...
While standard solar panels soak up the full light spectrum, UE Power only absorbs UV and near-infrared light. This makes the photovoltaic glass less efficient than standard solar panels, but the company claims that UE Power's versatility could lead to a larger-scale deployment, as the coating...
The particle shape structure (spherical, triangular, cube) has little effect on its near-infrared scattering efficiency [65]. TiO2 was partially coated on the surface of SiO2 particles. The formed TiO2–SiO2 (Janus) particles were coated on the fabric with higher near-infrared reflection ...
9969 Braille: deep Space 1 infrared spectroscopy, geometric albedo, and classification. Icarus 167, 129–135. The infrared (1.25–2.6 μm) spectra from DS1 indicate a 2-μm absorption and 1.6-μm reflectance peak, typical of silicate asteroids and similar to pyroxene minerals. Buratti et al...
