Thermoelectrics can be used for direct conversion of heat into electricity without moving parts, which is promising for sustainable energy harvesting. In this chapter, thermoelectric properties of oxide thin films: n-type ZnO and p-type Ca3Co4O9 are described in relation to preparation techniques, experimental conditions, substrates used, structure, and morphology. Nanostructuration and artificial nanodefects engineering as ultimate approaches to enhance the conversion efficiency of oxide thin films are also discussed.
