The Solar Cell Efficiency Tables, led by Professor Martin Green from UNSW, have been updated to Version 68 and will be available as open access in Joule starting from July 2026. The latest results show new efficiency records for large area silicon cells, modules, and lead halide perovskite cells. Progress has also been made with perovskite-silicon tandem cells and modules, indicating a positive trend towards more efficient and sustainable photovoltaic systems. Additionally, Version 67 presented a new record of 27.9% efficiency for an interdigitated-back-contact (IBC) device developed by Longi, showcasing significant advancements in solar cell technology since the tables were first published in 1993. Scientists from various institutions around the world, including the European Commission Joint Research Centre, Germany's Fraunhofer Institute for Solar Energy Systems, and the US National Renewable Energy Laboratory, have contributed to these advancements.
