The thermoelectric power generation efficiency of Bismuth monolayer nanoribbon has been studied theoretically‎. ‎We calculate the conductance of such a structure using the multi-orbital tight-binding‎ ‎model and also recursive Green's function method‎, ‎in the presence of substrate and on-site potential‎. For the case of ‎SiC ‎‎‎substrate-supported Bismuth nanoribbon and by proper selection of on-site potential, a boxcar shape conductance in terms of energy has been obtained‎. ‎‎Using the Landauer-‎B‎üttiker formalism in the nonlinear response regime, we calculate heat and charge currents ‎at low temperatures. By calculation of the electrical output power and power conversion thermoelectric efficiency, we have illustrated that such a structure can operate at high thermoelectric efficiency and also at a considerable power generation rate‎.
