Economic, efficient, and energy-saving preparation techniques were the key factors for the application of superconducting coated conductors. To shorten the preparation time and decrease the preparation cost, a speedy route of chemical solution deposition method was developed to prepare Ce0.8Sm0.2O1.9-Delta (CSO) layer on yttria stabilized zirconia single crystal substrate. TheCSObuffer layer was successfully obtained by the speedy route with the c-axis oriented structure and the smooth dense surface. The total time for the preparing CSO buffer layer could be shortened to around 70 mins. The thickness of CSO buffer layer was 150 nm. The YBa2Cu3O7-delta (YBCO) superconducting layer was grown on the CSO buffer layer with the superconducting transition temperature of 90.2 K and the critical current density of 1.83 MA cm(-2) (77 K, self-field). Hence, the speedy chemical solution deposition route could provide a low cost and efficient technology to prepare YBCO coated conductors.
