Spectrolab
Spectrolab is a manufacturer of space solar cells and panels headquartered in Sylmar, California. It is a subsidiary of The Boeing Company, and part of Boeing Defense, Space & Security. Spectrolab was founded in 1956 by Alfred E. Mann, a billionaire American entrepreneur and philanthropist. Spectrolab was originally a division of Textron. Spectrolab was acquired by Hughes Aircraft Company in 1975 and became a subsidiary of Hughes until its sale to Boeing in 2000. The company states its "NeXt Triple Junction" high efficiency solar cells have a minimum average efficiency of 29.5% to AIAA-2005-111 and AIAA-2005-112 requirements. In 2006 testing at the National Renewable Energy Laboratory demonstrated an efficiency of 40.7% using triple-junction solar cells developed by Spectrolab under concentration. In 2013, testing at the National Renewable Energy Laboratory demonstrated an efficiency of 38.7% without concentration, a new world record at the time. Spectrolab claims to h ...

Concentrated Photovoltaics
Concentrator photovoltaics (CPV) (also known as concentration photovoltaics) is a photovoltaic technology that generates electricity from sunlight. Unlike conventional photovoltaic systems, it uses lenses or curved mirrors to focus sunlight onto small, highly efficient, multi-junction (MJ) solar cells. In addition, CPV systems often use solar trackers and sometimes a cooling system to further increase their efficiency. Systems using high-concentration photovoltaics (HCPV) possess the highest efficiency of all existing PV technologies, achieving near 40% for production modules and 30% for systems. They enable a smaller photovoltaic array that has the potential to reduce land use, waste heat and material, and balance of system costs. The rate of annual CPV installations peaked in 2012 and has fallen to near zero since 2018 with the faster price drop in crystalline silicon photovoltaics. In 2016, cumulative CPV installations reached 350 megawatts (MW), less than 0.2% of the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hughes Aircraft Company
The Hughes Aircraft Company was a major American aerospace and defense contractor founded on February 14, 1934 by Howard Hughes in Glendale, California, as a division of Hughes Tool Company. The company was known for producing, among other products, the Hughes H-4 Hercules ''Spruce Goose'' aircraft, the atmospheric entry probe carried by the ''Galileo'' spacecraft, and the AIM-4 Falcon guided missile. Hughes Aircraft was founded to construct Hughes' H-1 Racer world speed record aircraft, and it later modified aircraft for his transcontinental and global circumnavigation speed record flights. The company relocated to Culver City, California, in 1940 and began manufacturing aircraft parts as a subcontractor. Hughes attempted to mold it into a major military aircraft manufacturer during World War II; however, its initial military projects ended in failure, with millions of dollars in U.S. government funds expended but only three aircraft actually built, resulting in a highl ...

Triple-junction Solar Cell
Multi-junction (MJ) solar cells are solar cells with multiple p–n junctions made of different semiconductor materials. Each material's p-n junction will produce electric current in response to different wavelengths of light. The use of multiple semiconducting materials allows the absorbance of a broader range of wavelengths, improving the cell's sunlight to electrical energy conversion efficiency. Traditional single-junction cells have a maximum theoretical efficiency of 33.16%. Theoretically, an infinite number of junctions would have a limiting efficiency of 86.8% under highly concentrated sunlight. As of 2008 the best lab examples of traditional crystalline silicon (c-Si) solar cells had efficiencies between 20% and 25%, while lab examples of multi-junction cells have demonstrated performance over 46% under concentrated sunlight. Commercial examples of tandem cells are widely available at 30% under one-sun illumination, and improve to around 40% under concentrated sunlight. ...

InGaP
Indium gallium phosphide (InGaP), also called gallium indium phosphide (GaInP), is a semiconductor composed of indium, gallium and phosphorus. It is used in high-power and high-frequency electronics because of its superior electron velocity with respect to the more common semiconductors silicon and gallium arsenide. It is used mainly in HEMT and HBT structures, but also for the fabrication of high efficiency solar cells used for space applications and, in combination with aluminium ( AlGaInP alloy) to make high brightness LEDs with orange-red, orange, yellow, and green colors. Some semiconductor devices such as EFluor Nanocrystal use InGaP as their core particle. Indium gallium phosphide is a solid solution of indium phosphide and gallium phosphide. Ga0.5In0.5P is a solid solution of special importance, which is almost lattice matched to GaAs. This allows, in combination with (AlxGa1−x)0.5In0.5, the growth of lattice matched quantum wells for red emitting semiconductor l ...

Germanium
Germanium is a chemical element with the symbol Ge and atomic number 32. It is lustrous, hard-brittle, grayish-white and similar in appearance to silicon. It is a metalloid in the carbon group that is chemically similar to its group neighbors silicon and tin. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature. Because it seldom appears in high concentration, germanium was discovered comparatively late in the discovery of the elements. Germanium ranks near fiftieth in relative abundance of the elements in the Earth's crust. In 1869, Dmitri Mendeleev predicted its existence and some of its properties from its position on his periodic table, and called the element ekasilicon. In 1886, Clemens Winkler at Freiberg University found the new element, along with silver and sulfur, in the mineral argyrodite. Winkler named the element after his country, Germany. Germanium is mined primarily from sphalerite (the primary ore of zinc), though ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sylmar, Los Angeles
Sylmar is a suburban neighborhood in the San Fernando Valley and is the northernmost neighborhood within the City of Los Angeles. Historically known for its profusion of sylvan olive orchards, Sylmar can trace its past to the 18th century and the founding of the San Fernando Mission. In 1890, olive production was begun systematically. The Sylmar climate was also considered healthy, and so a sanitarium was established, the first in a series of hospitals in the neighborhood. There are fourteen public and eight private schools within Sylmar. History Naming San Fernando became a city in 1874, leading to the naming of the unincorporated land surrounding San Fernando as Morningside. In 1893 the area was named Sylmar, a fusion of two Latin words for "trees" and "sea". Around 2000, some residents proposed a plan to rename the northwest portion of the district as Rancho Cascades. The name change was approved in 2018. Sylmar has been nicknamed "The Top of Los Angeles." Olives The f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
