Conquering a major technical obstacle

Korean scientists have achieved a significant breakthrough in solar energy technology, developing highly efficient perovskite solar cells with a certified efficiency of 20.6%. This surpasses the previous best efficiency of 19.2% and brings perovskite solar cells closer to the efficiency levels of traditional silicon panels. Perovskite is a cheaper and more readily available material than silicon, but has faced challenges with both efficiency and durability. However, recent advancements have improved its durability and efficiency, with experts believing it can achieve up to 27% efficiency in capturing solar energy. UniTest Co, a partner in the development of this technology, plans to commercialize the more efficient panels for use in applications such as semi-transparent solar roofs in cars and indoor perovskite solar cells on a mass scale by the end of the year. This breakthrough represents a significant milestone in the industry and research collaboration, with the Korea Research Institute of Chemical Technology president stating that it could contribute substantially to the commercialization of solar cell technologies. Scientists in China and Hong Kong have also made advancements in perovskite solar technology, indicating a promising future for the widespread implementation of solar energy worldwide.
