Researchers at the Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed a groundbreaking technology that allows smartphone batteries to be charged using transparent solar cells attached to the screen. This innovation could eliminate the need for bulky external battery packs, as phones could be charged simply using sunlight or indoor lighting. The Technology The research team, led by Professor Kwanyong Seo from the School of Energy and Chemical Engineering, has developed highly efficient and transparent solar cell modules. They used an “all-back-contact” (ABC) design that places all solar cell components on the rear side, maintaining … Continue reading Transparent Solar Cells Achieve 15.8% Efficiency: Smartphone Screen Charging Now Possible
