The latest edition of the Solar Cell Efficiency Tables, led by Professor Martin Green from UNSW, has been published as open access in the July 2026 issue of Joule. This version showcases record-breaking efficiencies for large area silicon cells and modules, advancements in lead halide perovskite cell development, and improvements in perovskite-silicon tandem cells and modules. Notable achievements include a 27.9%-efficient interdigitated-back-contact device developed by Longi. The research, which involves contributions from various institutions including the European Commission Joint Research Centre and the US National Renewable Energy Laboratory, highlights the continuous growth and advancements in photovoltaic technology.
