Emerging solar cell material sets new efficiency record
- On January 21, 2026, University of New South Wales researchers reported antimony chalcogenide reached 11.02% efficiency in lab tests, with independent CSIRO certification at 10.7%.
- Fixing the chemistry by adding sodium sulfide during the hydrothermal manufacturing process resolved uneven sulfur and selenium distribution that created an `energy barrier`.
- The material offers inorganic stability and low-temperature deposition with a 300 nanometers absorber, using abundant, inexpensive elements to harvest sunlight efficiently.
- A UNSW spinout, Sydney Solar, is upscaling transparent window stickers, but UNSW researchers warn passivation treatments are needed before rooftop and window deployment; the announcement follows Australia's national solar record last year.
- Dr. Qian said, `In the next few years, we will continue to work on reducing the defects in this material via that passivation process`, aiming for 12% efficiency and tandem cells with silicon for indoor and see-through window applications.

What if the future of solar is a material you’ve probably never heard of? - PVBuzzMedia
It’s called kesterite, and new research suggests it could match perovskites’ efficiency without any toxic lead in the stack. The post What if the future of solar is a material you’ve probably never heard of? appeared first on PVBuzzMedia.
