An international team of researchers led by Professor Martin Green at the University of New South Wales (UNSW), Australia, has published Version 66 of the Solar Cell Efficiency Tables in the journal Progress in Photovoltaics. The latest edition documents 21 newly verified results across a range of photovoltaic technologies.
Latest Efficiency Records Across Solar Technologies
The updated tables highlight several high-performance results, including a 27.81% efficiency achieved by Longi for its hybrid interdigitated back contact (HIBC) crystalline silicon solar cell. The tables also record a 26.1% efficiency for a kesterite (CZTSSe) cell developed by the Chinese Academy of Sciences.
Other notable additions include:
- A 26.9% efficient halide perovskite cell developed collaboratively by Soochow University and UNSW
- A 23.7% efficient mini perovskite module created by Microquanta
- A 27.3% efficient heterojunction back contact (BC) solar cell by Longi
- A 24.1% PERC cell manufactured by Trina Solar
- A 26.7% TOPCon cell and a 27.1% all-TOPCon interdigitated back contact (TBC) device produced by JinkoSolar
These results represent a broad cross-section of materials and device architectures, including crystalline silicon, perovskites, kesterites, and tandem structures.
Steady Growth Since Initial Publication
The solar cell efficiency tables were first introduced in 1993 and have become a standard reference for verified performance in photovoltaic research. The tables are updated biannually and include only independently confirmed results.
In Version 65, released in November, the group added 17 new results. The current version continues this trend, with further improvements across all categories of solar cell technology.
Global Collaboration in Verification and Reporting
The project involves contributions from several leading research institutions:
- European Commission Joint Research Centre
- Fraunhofer Institute for Solar Energy Systems (Germany)
- Institute for Solar Energy Research Hamelin (ISFH)
- National Institute of Advanced Industrial Science and Technology (Japan)
- National Renewable Energy Laboratory (United States)
Each result listed in the tables undergoes a rigorous third-party certification process, ensuring its accuracy and reproducibility.
