Silver doped YBa2Cu3O7-delta (YBCO) coated conductors were fabricated on Gd1.624Ho0.O-376(3) (100 % lattice match with YBCO) textured buffer layers on Ni tape by reel-to-reel sol-gel dip coating system. Sample were prepared with different wt(1-5) % Ag doped ratio. The surface morphologies and microstructure of all sample were characterized by ESEM, EDS and XRD. Pole figure texture analyses have been done to characterize texture of buffer layer and YBCO superconducting film. The critical current I-c measurement was performed using four wire method with the 1 mu V/cm criterion. The critical current density, J(c) was measured to be 2.2 x 10(4) A/cm(2) at 77 K self field for 1 wt % Ag doped YBCO sample.
