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 rear-contact design. SunPower’s latest A-300 solar cell achieves more than 20 percent efficiency, compared with currently available cells in the 12 to 15 percent range. The A-300 cell was developed and manufactured in SunPower’s Round Rock, Texas facility, which began operation in January 2003. The company’s initial products, introduced in 1992, were high-concentration solar cells with an efficiency of 26 percent. SunPower also manufactures a 22 percent efficient solar cell called Pegasus, which is the highest-efficiency non-concentrating silicon solar cell commercially available. An early application for the highly efficient and lightweight Pegasus solar cell was a high-altitude solar-powered aircraft. Pilotless solar-powered airplanes and blimps, which are nearing commercialization, can stay at a set altitude indefinitely and serve as telecommunications platforms over populated areas. SunPower solar cells were used on the NASA-sponsored AeroVironment airplane, “Helios,” that flew to a record altitude of 96,863 feet on August 13, 2001.
