Fraunhofer-ISE—and are reported on a standardized basis. The company At NREL, we see potential for photovoltaics (PV) everywhere. NREL is a national laboratory of the U.S. Department of Energy, Office of the global reference spectrum for flat-plate devices and the direct reference spectrum Cell efficiency results are provided within families of semiconductors: Some 28 different subcategories are indicated by distinctive colored symbols. 1121.7600098 0 0 589.6799927 0 0 cm However, the best value extracted from this document, is to see the broad building of knowledge that is occuring in advanced high efficiency solar cells. The “one-sun’ efficiencies for these cells are typically in the 30+% range but the structure is, in fact, optimized for concentration. may be used in presentations and publications, with a notation that states: "This In 2019, the world record for solar cell efficiency at 47.1% was achieved by using multi-junction concentrator solar cells, developed at National Renewable Energy Laboratory, Golden, Colorado, USA. The information plotted by NREL is provided in good faith, but NREL cannot accept A dual-junction solar cell jointly developed by NREL and the Swiss Center for Electronics and Microtechnology, which set a record with a conversion efficiency of 29.8%. If a photon strikes a solar cell and has less energy than the band gap, it gets absorbed as thermal energy. This is above the standard rating of 37.0% for polycrystalline photovoltaic or thin-film solar cells.
