Ovonic
Energy Conversion Devices (ECD) was an American photovoltaics manufacturer of thin-film solar cells made of amorphous silicon used in flexible laminates and in building-integrated photovoltaics. The company was also a manufacturer of rechargeable batteries and other renewable energy related products. ECD was headquartered in Rochester Hills, Michigan. Through its wholly owned Auburn Hills, Michigan, subsidiary United Solar Ovonic, LLC, better known as Uni-Solar, ECD was at one time the world's largest producer of flexible solar panels. Uni-Solar panels consisted of long rectangular strips with wiring at one end, which could be glued to any suitable supporting surface. They were widely used on flat roofs, motorhomes, semi-trailer cabs and similar roles. On February 14, 2012, Energy Conversion Devices, Inc. and its subsidiaries, United Solar Ovonic LLC and Solar Integrated Technologies, Inc. filed for bankruptcy in the U.S. United States District Court for the Eastern Distri ...

Nickel–metal Hydride Battery
A nickel metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the Nickel–cadmium battery, nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium. NiMH batteries can have two to three times the capacity of Nickel–cadmium battery, NiCd batteries of the same size, with significantly higher energy density, although much less than Lithium-ion battery, lithium-ion batteries. They are typically used as a substitute for similarly shaped non-rechargeable Alkaline battery, alkaline batteries, as they feature a slightly lower but generally compatible cell voltage, and are less prone to leaking. History Work on NiMH batteries began at the Battelle Memorial Institute, Battelle-Geneva Research Center following the technology's invention in 1967. It was based on sintering, sintered Ti2N ...

Thin Film Solar Cell
A thin-film solar cell is a second generation solar cell that is made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal. Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si). Film thickness varies from a few nanometers ( nm) to tens of micrometers ( µm), much thinner than thin-film's rival technology, the conventional, first-generation crystalline silicon solar cell (c-Si), that uses wafers of up to 200 µm thick. This allows thin film cells to be flexible, and lower in weight. It is used in building-integrated photovoltaics and as semi-transparent, photovoltaic glazing material that can be laminated onto windows. Other commercial applications use rigid thin film solar panels (interleaved between two panes of glass) in some of the world's largest photovol ...

Amorphous Silicon
Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon cells generally feature low efficiency. As a second-generation thin-film solar cell technology, amorphous silicon was once expected to become a major contributor in the fast-growing worldwide photovoltaic market, but has since lost its significance due to strong competition from conventional crystalline silicon cells and other thin-film technologies such as CdTe and CIGS. Amorphous silicon is a preferred material for the thin film transistor (TFT) elements of liquid crystal displays (LCDs) and for x-ray imagers. Amorphous silicon differs from other allotropic variations, such as monocrystalline silicon—a single crystal, and polycrystalline silicon, t ...

Chevron Corporation
Chevron Corporation is an American multinational energy corporation. The second-largest direct descendant of Standard Oil, and originally known as the Standard Oil Company of California (shortened to Socal or CalSo), it is headquartered in San Ramon, California, and active in more than 180 countries. Chevron is engaged in every aspect of the oil and natural gas industries, including hydrocarbon exploration and production; refining, marketing and transport; chemicals manufacturing and sales; and power generation. Chevron traces its history back to the 1870s. The company grew quickly after the breakup of Standard Oil by acquiring companies and partnering with others, especially Texaco. Socal was one of the Seven Sisters that dominated the global petroleum industry from the mid-1940s to the 1970s. In 1985, Socal merged with the Pittsburgh-based Gulf Oil and rebranded as Chevron; the newly-merged company later merged with Texaco in 2001. Today, Chevron manufactures and sells fu ...

Laminate
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a permanently assembled object created using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used. Materials There are different lamination processes, depending primarily on the type or types of materials to be laminated. The materials used in laminates can be identical or different, depending on the process and the object to be laminated. Textile Laminated fabric are widely used in different fields of human activity, including medical and military. Woven fabrics (organic and inorganic based) are usually laminated by different chemical polymers to give them useful properties like chemical resistance, dust, grease, windproofness, photolumine ...

Building-integrated Photovoltaics
Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or facades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power, although existing buildings may be retrofitted with similar technology. The advantage of integrated photovoltaics over more common non-integrated systems is that the initial cost can be offset by reducing the amount spent on building materials and labor that would normally be used to construct the part of the building that the BIPV modules replace. In addition, BIPV allows for more widespread solar adoption when the building's aesthetics matter and traditional rack-mounted solar panels would disrupt the intended look of the building. The term building-applied photovoltaics (BAPV) is sometimes used to refer to photovoltaics that are a retrofit – i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phase Change Memory
Phase-change memory (also known as PCM, PCME, PRAM, PCRAM, OUM (ovonic unified memory) and C-RAM or CRAM (chalcogenide RAM)) is a type of non-volatile random-access memory. PRAMs exploit the unique behaviour of chalcogenide glass. In PCM, heat produced by the passage of an electric current through a heating element generally made of titanium nitride is used to either quickly heat and quench the glass, making it amorphous, or to hold it in its crystallization temperature range for some time, thereby switching it to a crystalline state. PCM also has the ability to achieve a number of distinct intermediary states, thereby having the ability to hold multiple bits in a single cell, but the difficulties in programming cells in this way has prevented these capabilities from being implemented in other technologies (most notably flash memory) with the same capability. Recent research on PCM has been directed towards attempting to find viable material alternatives to the phase-change materia ...
