Produced at its solar cell plant in the Philippines, SunPower has had a full-scale solar cell verified by NREL (U.S. Department of Energy’s National Renewable Energy Lab) with a conversion efficiency of 24.2%. This is a new world record for c-Si cells. SunPower did not disclose any processing details that enabled the new record efficiencies or when such cells would enter volume production.
“This new world record demonstrates SunPower’s ability to extend our lead in manufacturing the world’s highest efficiency solar cells,” said Bill Mulligan, vice president of technology and development for SunPower. “Our patented and proprietary, high-efficiency solar cell technology drives down the cost of solar energy by increasing the energy production from each solar panel.”
SunPower also noted that it had increased its cell efficiencies a full four percentage points over the last five years. However, although the company also touted it had radically reduced manufacturing costs during the same period, SunPower has recently entered into a joint manufacturing partnership with Taiwan-based AUO to drive down manufacturing costs of its next-generation cells.
