KRICT has said it has achieved a world record energy conversion efficiency of 20.6% for perovskite solar cells with a large surface area of more than 200 cm².
The German Fraunhofer ISE has confirmed the result. According to KRICT, it beats the previous world record of 19.2% set by China’s UtmoLight.
“KRICT’s perovskite research team has optimized its in-house material synthesis methods, film uniformity through scalable processes and laser ablation control,” the research institute said in a statement. “The newly developed large-area, single-junction perovskite solar cell technology is directly applicable to large-scale production processes for perovskite-silicon tandem solar cells.”
KRICT said it is currently conducting outdoor stability tests (ISOS-O-1) on the new device and said South Korea-based UniTest plans to use the cell to commercialize its perovskite-based products.
“The company is also setting up facilities for the mass production of indoor perovskite solar cells, with the aim of starting production by the end of this year,” KRICT said.
The research institute did not provide additional technical details about the high-area perovskite cells.
