RFMD Produces Multi-junction Solar Photovoltaic Cell Using Six-Inch GaAs Wafer Fab
CompoundSemi News StaffMarch 15, 2010...As part of an ongoing collaboration with the NREL, RFMD, a company most known for its gallium arsenide (GaAs)-based radio frequency components, reports that it has successfully manufactured what it claims is the first photovoltaic cell made using high-volume six-inch gallium arsenide (GaAs) machinery. The photovoltaic (PV) cell was manufactured in RFMD's existing high-volume, six-inch GaAs wafer fabrication facilities in Greensboro, North Carolina USA. RFMD says that the manufacturing was done with no fabrication equipment modifications.
On July 1, 2009 RFMD announced it had entered into a cooperative agreement with the NREL to develop a commercially viable and high volume process to produce compound semiconductor-based multijunction PV cells.
The fabrication is part of the Foundation Phase of the project in which RFMD will establish its ability to manufacture the solar cells. The next phase will be the the Technology Demonstration Phase in which RFMD will leverage the NREL's intellectual property to produce the cells. Then in the final, Production Readiness Phase, RFMD's six-inch fabs will demonstrate production of high-performance PV cells with high yields, high reliability, high reproducibility and low cost.
NREL Director Dan Arvizu said, "NREL's collaboration with RFMD demonstrates our commitment to developing the best technologies for renewable energy and aligning with the most capable partners to commercialize and deploy each technology. We applaud RFMD's successful achievement of this first technical performance milestone."

Aixtron 2009 Final Year-end Financial Results First Solar to Provide 300 MW to PG&E from Desert Sunlight Project
CompoundSemi News StaffMarch 10, 2010...First Solar of Tempe, Arizona USA, announced a photovoltaic power purchase agreement to supply Pacific Gas and Electric Company electricity from a 300 megawatt (AC) photovoltaic solar power facility. First Solar is reportedly developing the solar power facility in Southern California. According to First Solar, the Desert Sunlight project, to be located near Desert Center in eastern Riverside County, Calif., will have a total capacity of 550 megawatts, enough to power approximately 160,000 area homes or provide power for 480,000 residents. The other 250 MW portion of the project is already under contract to Southern California Edison (SCE). First Solar's power purchase agreements with PG&E and SCE are subject to the approval of the California Public Utilities Commission.
First Solar will build the Desert Sunlight project using its cadmium telluride CdTe thin-film photovoltaic solar modules and provide its project development, engineering, procurement, and construction capabilities. Construction on the project is expected to start by the end of 2010, and completion is planned for as early as 2013. First Solar says that the project will create approximately 430 construction jobs. The project's permit application has been fast tracked by the Bureau of Land Management.
"First Solar is one of the few companies that has all the capabilities required to realize very large, utility-scale solar projects like Desert Sunlight, which are important in helping our customers and California reach the state's renewable energy goals," said Rob Gillette, First Solar chief executive officer.
First Solar News Release Georgia Tech Gets NASA Contract to Develop SiGe-based Phased Array Radar
CompoundSemi News StaffMarch 8, 2010...The Georgia Institute of Technology was awarded a $2.4 million contract from the National Aeronautics and Space Administration (NASA) to develop a new radar system, according to an article
from Georgia Tech. The radar system will study and map ice and snow formations from the air.
The phased-array radar will use
silicon-germanium (SiGe) chips in combination with radio-frequency micro-electromechanical systems (RF MEMS). The light weight systems could be placed on aircraft or satellites.
Previously, such mapping required heavy radar equipment that required surface operation, according to John Papapolymerou, a professor in Georgia Tech's School of Electrical and Computer Engineering and principal investigator on the project. The system would allow unmanned aerial vehicles (UAVs) to gather information by flying over a large area such as Greenland, using the radar system to map ice sheets in three dimensions.
While conventional radar requires a mechanical repositioning of an antenna, the new system would use phase shifting to electronically steer the signal beam. An 8 by 8 grid of fixed, interconnected antenna elements send and receive multiple radar signals virtually simultaneously.
Cressler,a Ken Byers Professor in the School of Electrical and Computer Engineering, said,"Using silicon-germanium allows much higher levels of integration, which older radar systems don’t give you," He added, "It enables you to go from a system which is much larger and more expensive, and less robust, to a chip that is only a few millimeters on a side and costs far less." Efficient Power Conversion Corporation Introduces 40 V to 200V Enhancement Mode GaN Power Transistors
CompoundSemi News StaffMarch 8, 2010...Efficient Power Conversion Corporation (EPC) of El Segundo, California USA introduced a family of enhancement mode power transistors. The transistors are based on EPC's proprietary gallium nitride on silicon technology.
They span a range of 40 Volts to 200 Volts, and 4 milliohms to 100 milliohms. The company says that the power transistors demonstrate significant performance advantages over state-of-the-art silicon-based power MOSFETs. EPC’s technology produces devices that are smaller than similar resistance silicon devices and have many times superior switching performance. Applications such as DC-DC power supplies, point-of-load converters, class D audio amplifiers, notebook and netbook computers, LED drive circuits, telecom base stations, and cell phones can reportedly benefit from the improved performance.
EPC notes that its enhancement mode (normally OFF) GaN technology was explicitly developed to replace power MOSFETs. The transistors are produced in a standard silicon CMOS foundry on 150mm (6 inch) silicon wafers. “EPC’s GaN on silicon power transistors represent the first major breakthrough in power conversion technology since the development of the commercial power MOSFET. We have developed a very cost effective and reliable technology that is also very easy for anyone with power MOSFET experience to use in a way that will significantly boost their power management system performance,” said Alex Lidow, EPC’s co-founder and Chief Executive Officer.
