Australian researchers set a world record with antimony chalcogenide solar cells at 11.02% efficiency, using sodium sulfide to boost performance.
Researchers at the University of New South Wales achieved a world record 11.02% efficiency in antimony chalcogenide solar cells, with 10.7% independently verified by CSIRO.
By adding sodium sulfide to the precursor solution, they improved elemental distribution, reduced energy barriers, and enhanced charge transport.
The material’s low-cost, abundant components, low-temperature processing, and suitability for tandem, transparent, and indoor applications make it a promising next-generation solar technology.
Further gains up to 12% are possible with defect passivation.
