SunPower Presents at DOEs Solar Energy Technology Program Review Meeting

10/28/2004 - SunPower Corp., a subsidiary of Cypress Semiconductor Corp. (NYSE: CY), announced that its founder and president, Dr. Richard Swanson, will be presenting at the U.S. Department of Energy’s (DOEs) Solar Energy Technologies Program Review Meeting, being held this week at the Denver Marriott Tech Center Hotel in Denver, Colo. Dr. Swanson’s invited plenary presentation, “A Vision for Crystalline Silicon Solar Cells,” will be on Wednesday, October 27 at 9:30 a.m.

The DOE’s program review meeting is held annually to review and report on all research and development activities. A wide variety of technologies are discussed, ranging from photovoltaics, concentrating solar power, and solar heating and lighting.

Dr. Swanson is a reknowned expert in the photovoltaic arena. While a professor at Stanford University, Swanson’s team developed a unique silicon solar concentrator cell with funding from the Electric Power Research Institute and the U.S. Department of Energy. The cell features rear-mounted electrical connections that make the solar cell’s entire front surface available to sunlight and subsequently more efficient. The technology earned R&D Magazine’s R&D 100 Award in 1994. Dr. Swanson earned both his bachelors and masters degrees in electrical engineering from Ohio State University and his Ph.D from Stanford University, before establishing SunPower.

SunPower’s new A-300 solar cell features a unique, all-back-contact design that maximizes working cell area, hides unsightly wires and simplifies automated production. The National Renewable Energy Laboratory (NREL) recently measured the A-300’s power efficiency at an industry-best 21.5 percent; where competing production cells typically measure in the 12- to 15-percent range. The cell’s low voltage-temperature coefficient, exceptional low-light performance and high sensitivity to light across the entire solar spectrum enable the A-300 to convert virtually every accessible photon into useable electricity, maximizing annual energy production.

About SunPower
SunPower—a majority-owned subsidiary of Cypress Semiconductor Corp. (NYSE: CY)—designs and manufactures high-performance silicon solar cells based on an interdigitated all-back-contact design. The company’s initial products were put to use in a variety of high-performance applications, including the NASA-sponsored AeroVironment airplane, “Helios,” that flew to a record altitude of 96,863 feet on August 13, 2001. SunPower manufactures its high –performance A-300 solar cells in a new facility outside of Manila, the Philippines. The company currently operates a 25 MW production line there, and is planning to ramp production to more than 100 MW.
