The quest for good thermoelectric materials and/or high-efficiencythermoelectric devices is of primary importance from theoretical and practicalpoints of view. Low-dimensional structures with quantum dots or molecules arepromising candidates to achieve the goal. Interactions between electrons,far-from-equilibrium conditions and strongly non-linear transport are importantfactors affecting the usefulness of the devices. This paper analyses thethermoelectric power of a two-terminal quantum dot under large thermal $\DeltaT$ and voltage $V$ biases as well as the performance of the three-terminalsystem as a heat engine. To properly characterise the non-linear effects underthese conditions, two different Seebeck coefficients are introduced,generalizing the linear response expression. The direct calculations ofthermally induced electric and heat currents show, in agreement with recentwork, that the efficiency of the thermoelectric heat engine as measured by thedelivered power is maximal far from equilibrium. Moreover, the strong Coulombinteractions between electrons on the quantum dot are found to diminish theefficiency at maximum power and the maximal value of the delivered power, bothin the Kondo regime and outside of it.
