摘要：

The Na(0.5)Co(0.9)Cu(0.1)O(2)thick film with the same thermoelectric performance as a Na(0.5)CoO(2)bulk was formed on an alumina substrate by the screen-printing process. The power factor exceeded 0.3 mW/K(2)m, with the resistivity of 3.8 m omega cm and the thermopower of 108 mu V/K. The thick film without any cracks strongly adhered to the substrate. The high-quality thick film had been realized through the carefully designed and improved process, mixing NaCl to promote the anisotropic sintering of Na0.5Co0.9Cu0.1O2, inserting a CuO interlayer to adhere the film and substrate, and Co-Cu substituting Cu for Co to control the sintering temperature.
