Abstract : Under Phase I, JX Crystals has increased the power output from its cylindrical thermophotovoltaic generator from 71 Watts to 132 Watts and it has developed a better understanding of the thermal design parameters. Independently, it has discovered an infrared emitter with a spectral output which is very well matched to the spectral response for its GaSb cells. Using this new emitter, JX Crystals predicts that the output of its thermophotovoltaic generator can still be substantially improved.
