Chemical Solution Deposition (CSD) is a promising process for industrial long length production of high temperature superconducting tapes because of its low-cost, high-speed production and good scalability. YBa2Cu3O7-x (YBCO) coated conductors are the favourable material with excellent superconducting properties including sufficient high Jc-performance. Nevertheless, the alternating current (ac)-losses are still too high for applications of wires in motors. A special plotting technique allows a printing of filamented structures of YBCO thin layers. The hysteresis losses in such striped films are much lower than in continuously coated substrates with a homogeneous YBCO layer.
Lines as well as rectangular shaped YBCO-structures were deposited by an ink plotting system on single crystal substrates. Different inks were tested, among them an environmentally friendly, water-based fluorine-free YBCO precursor solution as well as an ink, synthesised according to the TFA route.
