According to pv international magazine.
Qcells has set a world record for efficiency for a tandem solar cell on a full-area M10 size cell suitable for mass production.
The South Korean company achieved an efficiency of 28.6% on a 330.56 cm² cell manufactured on its pilot line in Germany.
The solar cell uses perovskite technology for the upper cell and proprietary Q.ANTUM technology for the lower cell. Qcells explains that this tandem structure improves performance by allowing the top cell to more efficiently capture high-energy light while the bottom cell captures low-energy transmitted light.
“This improves power per area and therefore fewer modules are needed to achieve the same solar system power,” the company said in a statement. “This advancement could further reduce the cost of solar energy and the land footprint required for solar projects, making solar energy even more affordable, more accessible and more sustainable. »
The CalLab of the Fraunhofer Institute for Solar Energy Systems (ISE) independently verified this record result.
Danielle Merfeld, Qcells’ global technical director, said the tandem cell “will accelerate the process of commercializing this technology and ultimately enable a big leap forward in photovoltaic performance.”
