ABSTRACT:
In the present invention, a thermophotovoltaic electric power generator is described. It contains low bandgap photovoltaic cells sensitive in the infrared out to at least 1.7 microns and a broadband infrared emitter with a shortpass IR filter located between the cells and the emitter to recycle the nonuseful IR back to the emitter. Several specific IR filter designs as well as filter/cell and filter/emitter combinations are described all of which improve the overall generator conversion efficiency.
