Companies Set Performance Records
Surpassing its previous world record for a standard triple-junction concentrating photovoltaic (CPV) cell, Solar Junction and Wales-based IQE have achieved 44.1 percent cell efficiency for production-qualified wafers, verified by the National Renewable Energy Laboratory (NREL).
CPV manufacturer Amonix has achieved an NREL-verified efficiency rating of 35.9 percent under new CPV IEC test conditions of 1,000 watts per square meter and 77°F (25°C) cell temperature.
The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin have announced a record 44.7 percent efficiency for a multi-junction PV solar cell.
The Centre for Solar Energy and Hydrogen Research Baden-Württemberg has set a new copper indium gallium diselenide (CIGS) thin-film solar cell efficiency record of 20.8 percent. Confirmed by Fraunhofer ISE, the record marks the first time a thin-film solar cell has surpassed multicrystalline PV cell efficiency.
Semprius has set a new record of 35.5 percent for mass-produced CPV modules, confirmed by Fraunhofer ISE. The technology incorporates standard production techniques and materials, including epitaxial wafers provided by Solar Junction.
