Korean scientists have improved perovskite solar cells, helping to make solar energy more efficient and cost-effective.Korean scientists have achieved a breakthrough that could greatly advance the use of solar energy worldwide. According to Interesting Engineering, the Korea Research Institute of Chemical Technology and UniTest Co have jointly developed a technology to produce large-area perovskite solar cells with a certified efficiency of 20.6%, surpassing the previous record of 19.2%. As reported by GreenMatch, traditional solar panels typically have an efficiency range of 15% to 22%, but they are expensive to produce, resulting in higher costs for consumers.

Perovskite, a cheaper and more abundant material than silicon, has faced challenges in both efficiency and durability. However, significant progress has been made in improving its durability, and now its efficiency is on par with silicon panels. As noted by Interesting Engineering, experts believe that perovskite can achieve up to 27% efficiency in capturing solar energy, and this latest achievement brings us closer to that goal.
“This accomplishment is a major milestone in overcoming a key technical barrier for the commercialization of large-area perovskite cells. It is a significant success in the collaboration between industry and research, and we hope it will greatly contribute to the commercialization of solar cell technologies,” said Young-Kook Lee, president of the Korea Research Institute of Chemical Technology.
In China, scientists have developed a hybrid perovskite model with an efficiency of over 26%, while researchers in Hong Kong have discovered a method to further enhance its efficiency. UniTest plans to expedite the commercialization process for this technology and bring more efficient panels to the market as soon as possible. They aim to use the technology for applications such as semi-transparent solar roofs for cars and mass-produce indoor perovskite solar cells by the end of the year.
