21 new entries in Martin Green's latest "Solar Cell Efficiency Tables"

The latest version of the PV industry’s beacon of progress, the “Solar Cell Efficiency Tables” was released in May. Now in its 66th edition, the Tables remain the gold standard for tracking the highest independently confirmed efficiencies in photovoltaic (PV) technologies.

Led by Professor Martin Green of UNSW and published biannually in Progress in Photovoltaics: Research and Applications, this series has become one of the most cited and influential resources in solar energy research. Its rigorous methodology and global recognition make it a cornerstone for both academic and industrial stakeholders seeking to benchmark and validate solar cell performance.

Version 66 introduces 21 new entries across various categories of solar cells and modules. Professor Martin Green said, “There are some great results in the latest Tables including 26% for a module, and 27.3% for a perovskite cell with UNSW involved."

“Longi, JA, Trina and Jinko are all working hard and posting new records.”

ACAP Executive Director Renate Egan said, “These terrific results reflect a surge in industry effort and outcomes.”

Significantly, the July 2025 edition has a new category (Table 3) for high ‘effective bandgap’ cells. These cells are potential contenders for upper cells in tandem cell stacks and are now included to increase the exposure of more stable top cell alternatives to perovskites.

It is important to note that stability is as critical to the commercial success of solar technology as efficiency.

This study is an international collaboration with Martin A. Green, Ewan D. Dunlop, Masahiro Yoshita, Nikos Kopidakis, Karsten Bothe, Gerald Siefer, Xiaojing Hao, Jessica Yajie Jiang, and is supported by the Australian Renewable Energy Agency through the Australian Centre of Advanced Photovoltaics (ACAP), in partnership with the US Department of Energy and Japan's Ministry of Economy, Trade and Industry.
