Work Detail The research group led by Professor Martin Green has published version 65 of the solar cell efficiency tables. The new version includes 17 new results. The international research group led by Professor Martin Green of the University of New South Wales (UNSW) in Australia has published Version 65 of the “Solar Cell Efficiency Tables” in Progress in Photovoltaics . Scientists say they have added 17 new results to the new tables since June. “The first is a further increase in one of the most important inputs, the efficiency of a silicon solar cell,” Green told pv magazine . “Following the 27.3% increase reported in Release 64 for a commercial-sized cell manufactured by Longi with both polarity contacts on the back of the cell formed using the heterojunction (HJT) method, this has been increased to 27.4% for a similar-sized cell manufactured by Longi again with both contacts on the back but in this case using a hybrid method, with the n-type contact using the TOPCon method.” “Another new result was 27.0% for a similar cell with rear contact from Longi but with both polarity contacts using the TOPCon approach,” he went on to say. “A third new result is 25.9% for the traditional front-back contact approach of a Trina cell with the p-type top contact formed by boron diffusion and the n-type back contact using the TOPCon approach. A final new result for silicon was 25.4% for a large 1.8 m2 solar module also from Longi on the basis of aperture area.” The tables also include several new results for lead halide perovskite cells. “Perhaps the most striking is the 26.9% for a large 1.6 m2 module from Oxford PV, also based on aperture area, which uses a combination of cells with a perovskite cell deposited on top of each silicon cell – a tandem cell approach that will likely lead to module efficiencies well above 30%,” Green explained. “The notable feature of this result is that for the first time it sits comfortably above the 25.4% efficiency of a similarly sized module using silicon cells alone – a feature necessary for commercialisation of this approach.” Efficiencies of 17.2% have also been reported for a large 0.7 m2 module from Renshine using only perovskite cells, with higher values ??of 20.6% and 23.2% reported for smaller perovskite “minimodules” of 215 m2 and 20 m2 from other groups and 24.8% for a 64 m2 minimodule of perovskite/perovskite tandem cells. "Other notable perovskite results include new records of 34.6% and 30.1% for Longis 1 m2 and 212 m2 perovskite/silicon tandem cells and 25.1% for a very small perovskite/organic tandem cell," Green explains. The last group of results concerns cells based on chalcogenide compounds (group VI), which offer a potential alternative to perovskites if the latter cannot be substantially improved in stability. The efficiency of small-area CdTe cells has been improved to 23.1% by First Solar, while UNSW Sydney has also been involved in setting new efficiency limits of 13.2% and 10.7% for small Cu2ZnSnS4 and Sb2(S,Se)3 cells and the Chinese Academy of Sciences has set a figure of 12% for a Cu2ZnSn(S,Se)4 mini-module. In version 64 of the tables, published in June, the researchers added nine new results. The group has observed significant improvements in all cell categories since 1993, when the tables were first published. The research group consists of scientists from the European Commissions Joint Research Centre, the Fraunhofer Institute for Solar Energy Systems and the Institute for Solar Energy Research (ISFH) in Germany, the National Institute of Advanced Industrial Science and Technology in Japan and the National Renewable Energy Laboratory in the United States.
