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

have been obtained. Superconducting YBCO films were grown by the trifluoroacetates route on top of metal organic deposited (Ce, Zr) O
