Researchers at Daegu Gyeongbuk Institute of Science and Technology (DGIST) have developed film-type, graphene-based multi-functional transparent energy devices.
Senior researcher Changsoon Choi's team actively used single-layered graphene film as electrodes in order to develop transparent devices. By using a high-molecule nano-mat that contains a semisolid electrolyte, the research team increased transparency (maximum of 77.4%) to see landscape and letters clearly.
Senior researcher Changsoon Choi in the Smart Textile Research Group, the co-author of the paper, said, "We decided to start this research because we were amazed by transparent smartphones appearing in movies. While there is still a long way to go for commercialization due to high production costs, we will do our best to advance this technology further."
