Low-temperature CuInS₂ solar cells edge past 12.2% mark after nearly 30 years

The research team of Professor Wang Mingtai at the Institute of Solid State Physics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, developed a low-temperature solution-processing strategy for fabricating CuInS2 thin-film solar cells and achieved a CuInS2 solar cell with an efficiency of up to 12.28%. Their findings were published in Joule.
