SEMICONDUCTORS and conductors made of carbon could one day be used in planes and cars that collect and store their own solar energy. Carbon composites are built by cementing together layers of carbon fibres using epoxy resin. By doping the fibres with chemicals that donate or mop up electrons, Deborah Chung and Shoukai Wang of the State University of New York at Buffalo have found a way to make them act as conductors and semiconductors. By combining these fibres in layers, Chung says she can build solar cells, capacitors and other electronic components that can be wired together with conducting fibres. “They’re very cheap to make compared with silicon technology,
