Researchers at the Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed transparent solar cells that can be integrated into mobile devices, vehicles, and building glass, transforming sunlight into electricity.
Led by Professor Kwanyong Seo from the School of Energy and Chemical Engineering, the team employed an “All-Back Contact” design. This innovation positions all components on the cell’s rear, maintaining front surface transparency and eliminating visible connections such as metal wires and cords. The development of Seamless Modularization technology further bridges gaps between individual cells.
Professor Seo highlighted the role of this breakthrough in advancing eco-friendly energy solutions and mentioned ongoing efforts to bring these solar cells to market.
The research team demonstrated the practical application of their 16 cm² solar cell module, which shows high efficiency and maintains 20% to 14.7% transparency. They successfully used the cells to charge a smartphone with sunlight, showcasing the technology’s potential as a sustainable energy source.
