Researchers and corporations around the globe continue to invest resources in research and development in the area of solar cells composed of organic or carbon-based semiconductors. Recent developments in Organic Photovoltaics or OPV, referred to in the industry as "third generation photovoltaics,” have a significant impact for portable, low power electronic devices and other areas. Consumers may soon have the ability to charge their cell phones, laptops, or tablets with an inexpensive, credit card size solar charger integrated with the battery, even while using devices under low light conditions on the interior or exterior. Scientists from the University of Warwick and Molecular...

A paper published in the August 2012 edition of Nature Photonics states that Tyndall National Institute - University College Cork, Semprius Inc., and Seagate Technology have developed an innovative semiconductor fabrication technology. The development allows manufacturers to integrate a high power compound semiconductor laser structure with a silicon substrate, according to Compound Conductor. The new technology holds significant promise for meeting growing storage demands because it can provide high-capacity, high-performance, and low-cost storage solutions. Micro-Transfer Print Technology One of the keys to the breakthrough involved the use of proprietary micro-transfer print technology owned by North Carolina-based Semprius. The company manufactures high concentration photovoltaic...

After shipping the scrubber to your location, CSI will send one of our highly trained facilities engineers to evaluate the abatement end of your system evaluate how the point-of-use scrubber fits into that system install the gas scrubber. Training effectively begins during the installation and start up of the gas scrubber, and typically continues for an additional 6-8 hour period, including a “walk through” of the documentation. After that, we will provide unlimited phone support free of charge. Additionally, we provide reasonably priced on-site service calls and preventative maintenance service contracts performed by highly experienced gas abatement technicians....

Why replace a tungsten electrode? Even though orbital welding is a very consistent process in and of itself, the frequency for replacing a tungsten electrode will likewise vary widely. Wall thickness, tube diameter and material, weld recipe values, quality of the inert gas shield, and many other parameters can all play a role in the service life of the electrode.   A tungsten may fail in a single weld, or run 700+ cycles. One example of what can happen when an electrode goes bad is the ‘roll back’. The weld may start normally, but part way through the arc does not follow the...

A Feed-In-Tariff (FiT) allows residential property owners, businesses, and electric utility companies that generate electricity to sell the energy. The seller receives long-term payments for each kilowatt-hour (kWh) of energy sold. Acceptable energy technologies include wind, biomass, photovoltaic (PV), and solar thermal energy. The Carter Administration introduced the first FiT in 1978 as part of the National Energy Act (NEA), which Congress passed in response to the Arab Oil Embargo. Feed-in-tariffs epitomizes the one global policy that has fueled the most aggressive growth of renewable energy resources over the last ten years. At the end of 2011, world-wide photovoltaic installation totaled 67.4...

A team of researchers from North Carolina State University and the Georgia Institute of Technology have developed a more cost-effective way to manufacture textured, nickel ferrite (NFO) ceramic thin films. The new technology uses a chemical vapor deposition (CVD) process, which allows researchers to build thin films with an ordered crystalline array. This structure enhances the material’s magnetic qualities. NFO magnetic technology holds immense potential for next-generation memory technologies and microwave devices. Chemical Vapor Deposition The chemical vapor deposition (CVD) process refers to a category of manufacturing procedures commonly used in the semiconductor and solar industries.  The procedures concern the deposit of a...

Researchers at the University of Bristol’s Centre for Quantum Photonics have collaborated with scientists from Delft University (Netherlands) and Heriot-Watt University (Scotland) to develop a process to manufacture functioning quantum chips from silicon. Silicon is the same material used to produce microprocessors for PCs, laptops, and smart phones. Traditional computing relies on a  ‘bit’ as the basic unit for coding computer information. A bit has a value of either 0 or 1. Quantum computing replaces a bit with a ‘qubit’. Like a bit, a qubit can also have two possible values – 0 or 1. However, a qubit has the ability...

At the start of the year, many semiconductor market analysts predicted the worldwide semiconductor market would grow at a marginal annual rate of around 3 percent in 2012. However, a weak global economy, especially in the U.S., Europe, and China, has led to a downward revision in the forecast. The market intelligence firm IHS iSuppli recently revised its data to reflect a 1.4 percent rate of growth – unchanged from 2011. For the last several quarters, significant expansion of the wireless segment has boosted the semiconductor industry in the midst of a weak global economy. The “downward pressure" created by...
