Results show that the rareearth emitter and T CO filter greatly increase the thermoelectric conversion efficiency of the system, but decrease its output pow er density, especially the T CO filter play an obvious negative role in this aspect. Compared w ith a solar photovoltaic system, the TPV system has a low er generation cost, and therefore may result in higher economical effects.
