An international research group led by Professor Martin Green from the University of new south wales in Australia has published Version 61 of the “solar cell efficiency tables” in Progress in Photovoltaics. The scientists said they have added six new results to the new tables since June.
“The tables include the result announced this week by Chinese manufacturer Longi, which achieved a 26.81% efficiency of rating for an n-type silicon heterojunction (HJT) cell fabricated on an M6 wafer,” Green told pv magazine
. “They also include the 26.6% efficiency achieved by Longi for an M6 p-type bifacial cell.”
The results include a 31.3% efficiency for a 1-square-centimeter device fabricated by the Swiss center for Electronics and Microtechnology (CSEM) and the Ecole polytechnique federals de Lausanne (EPFL), and a 22.4% efficiency rating for a 26-square-centimeter perovskite mini-module obtained by EPFL and North China Electric Power University (NCEPU). The results also include a 24.5% efficiency rating for a 20-square-centimeter perovskite/perovskite two-junction, two-terminal mini-module made by Nanjing university and Ren shine Solar, and a 47.6% efficiency of rating for a four-junction, wafer-bonded concentrator cell based on Group III-V cell technology, with the cell fabricated and measured by the Fraunhofer Institute for Solar Energy System (Fraunhofer ISE).
In Version 60 of the tables, released in June, the researchers added 15 new results. The group has seen major improvements in all cell categories since 1993, when the tables were first published. The research group includes scientists from the European Commission Joint Research Center, Germany’s Fraunhofer Institute for Solar Energy Systems, Japan’s National Institute of Advanced Industrial Science and Technology, the US Department of Energy, and the US National Renewable Energy Laboratory.
