Researchers at the Okinawa Institute of Science and Technology Graduate University’s (OIST) Energy Materials and Surface Sciences Unit have found that growing a type of film used to manufacture solar cells in ambient air gives it a growth boost. The finding, which could make manufacturing solar cells significantly cheaper, was published in Chemistry of Materials […]
