The research group led by Professor Martin Green has published Version 68 of the solar cell efficiency tables. There are 21 new results reported in the new version.

The international research group led by Professor Martin Green from the University of New South Wales (UNSW) in Australia has published Version 68 of the “Solar Cell Efficiency Tables” in Joule.

“One major change is that the Tables will be appearing ‘open access’ in the July 2026 issue,” Green told pv magazine. “This change reflects the growing photovoltaic impact in mainstream energy and the scientific progress achieved over the 33 years of publications of these tables. The biannual publication of the open access Tables will continue in Joule on the regular schedule of January and July. The authors are excited by this opening to a broader readership and by the continued growth of the photovoltaic community.”

Version 68 reports 21 new results. “Two of the most exciting are new records for both large area silicon cells and modules, with 28.1% efficiency reported for a large cell, 140-cm2 in area, and 26.4% for an encapsulated 1.9-m2 module,” Green added. “The cell and the module were both fabricated by Longi, with both positive and negative polarity contacts on the rear of all the cells involved.”
