Density functional theory and the Boltzmann transport equation were used to calculate the thermoelectric transport coefficients for bulk V 2O5 and MV2O5 (M = Cr, Ti, Na, Li). The structural relaxation for the given compounds based on the ABINIT code was observed. The temperature dependences of the Seebeck coefficients as well as electrical and thermal electrical conductivities of all relaxed structures displayed anisotropic behavior. Electrooptical measurements of thermoelectric properties were carried out on V2O5 thin films obtained by thermal evaporation with different post-annealing treatments. A Seebeck coefficient of -148 μV/K at T = 300 K was obtained in the in-plane direction for V2O5 thin films with thickness less than 100 nm.
