Growth of Chemical Solution Deposited $^{\rm TFA}{\rm YBCO}/^{\rm MOD}({\rm Ce},{\rm Zr}){\rm O}_{2}/^{\rm ABAD}{\rm YSZ/SS}$ Coated Conductors

All chemical solution deposited coated conductors on ^ABADYSZ/SS tapes with critical current densities at 77 K of J_c = 1.8 MA / cm² have been obtained. Superconducting YBCO films were grown by the trifluoroacetates route on top of metal organic deposited (Ce, Zr) O₂ buffer layers. Planarity of the CZO layer is the key for the high quality growth of the ^TFAYBCO films reaching J_c (77 K, sf) = 5.2 MA / cm². Granularity effects dominate J_c (H) at low fields while, at 77 K, for fields above 2 T, J_c of the coated conductor exhibits the same value as those obtained on single crystals.
