A breakthrough in solar cell technology has been achieved by a team of researchers at the Korea Research Institute of Chemical Technology (KRICT) in collaboration with UniTest, a Korean semiconductor equipment maker. The development of a large-area perovskite solar cell with an efficiency of 20.6 percent has set a new world record, surpassing the previous record of 19.2 percent held by China. This innovative technology has been recognized by Fraunhofer, a prestigious certification body in Germany, and will be listed on the U.S. National Renewable Energy Laboratory’s solar cell efficiency chart.

The Significance of Perovskite Solar Cells

Perovskite, an oxide with semiconductor properties, has emerged as a promising material for solar cells due to its high efficiency and cost-effectiveness compared to traditional silicon cells. The development of large-area perovskite solar cells has sparked intense competition among countries like Korea, China, and the Middle East to commercialize this technology. However, achieving an efficiency of over 20 percent has been a significant challenge.

Optimizing Efficiency Through Innovation

One of the key factors in enhancing the efficiency of perovskite solar cells is ensuring coating uniformity and optimizing the laser process. The complexity of large-area devices makes it difficult to fine-tune various elements, but through meticulous material synthesis, coating uniformity, and laser power optimization, the KRICT team succeeded in achieving a remarkable efficiency of 20.6 percent.

Future Applications and Collaborations

The large-area perovskite solar cell technology developed by KRICT and UniTest opens up possibilities for applications in tandem solar cells and even panoramic solar roofs for cars. By collaborating with Korean automobile manufacturers, UniTest aims to integrate translucent perovskite solar cells into vehicles, expanding the reach of this innovative technology.


The breakthrough in perovskite solar cell technology marks a significant milestone in the renewable energy sector. The development of large-area cells with record-breaking efficiency not only showcases Korean innovation and expertise but also paves the way for a more sustainable future. As countries continue to invest in solar energy research and development, collaborations like the one between KRICT and UniTest highlight the importance of cross-sector partnerships in driving technological advancements and addressing global energy challenges.
