A research team led by Professor Jun Yong-seok from the Department of Integrative Energy Engineering and the Graduate School of Energy and Environment (Green School) at KU (President Kim Dong-One), in collaboration with research teams from Korea Aerospace University and the Korea Institute of Science and Technology (KIST), has developed a transparent solar window technology that can generate power 24 hours a day using sunlight during the day and indoor lighting at night.
The research results were published online on November 21 and published in print on December 17 in Joule (IF=35.4), a world-renowned international academic journal in the energy field.
*Article title: Scalable hybrid solar window with high transparency, high efficiency, and superior color rendering
*DOI: 10.1016/j.joule.2025.102216
*URL: https://doi.org/10.1016/j.joule.2025.102216 Existing transparent solar cells face a contradiction: increasing transparency leads to a decrease in power generation efficiency, while increasing efficiency reduces transparency. Moreover, thin-film solar cells distort the color of light during the absorption process, creating limitations for their application as building-integrated photovoltaics (BIPV).
