On August 22, 2013, IQE plc, a global leader in semiconductor wafer manufacturing, announced that its high-volume production materials had achieved a photovoltaic cell efficiency of 44.1%—a record certified by the National Renewable Energy Laboratory (NREL). This breakthrough surpassed the previous world record set by Solar Junction, a leading developer of multi-junction solar cells for concentrated photovoltaic (CPV) systems.
Solar Junction, based in Silicon Valley, relies on high-capacity MBE (molecular beam epitaxy) tools provided by IQE to produce its advanced photovoltaic cells. These cells are designed for concentrated sunlight applications, where efficiency is key to maximizing energy output.
In October 2012, Solar Junction had already set a milestone with a power conversion efficiency of 44% under a sunlight intensity of 947 W/m², breaking their own previous record of 41.35% from April 2011. Both achievements were independently verified by NREL, highlighting the company’s ongoing progress in CPV technology.
Viijit Sabnis, CEO of Solar Junction, emphasized the significance of this achievement, stating, “Breaking the world record is a major accomplishment. It reflects our strong collaboration with IQE, our advanced dilute nitride technology, and the dedication of our team. We remain committed to advancing multi-junction solar cell production, improving efficiency, and reducing CPV costs to benefit end users.â€
Dr. Drew Nelson, CEO of IQE, added, “The successful certification of our high-capacity 4-inch and 6-inch CPV technology marks another significant milestone for IQE. Achieving battery efficiencies that exceed previous records from Solar Junction demonstrates our leadership in the field. Improvements in CPV efficiency directly translate to lower installation and energy generation costs, making solar power more competitive and accessible.â€
