Abstract

Spectral control in thermophotovoltaic systems (TPV) is critical to achieving high thermal to electric conversion efficiency and power density. Closed thermal systems using a fixed heat source such as radio-isotope TPV, require the recuperation of below bandpass photons to maintain the temperature of the thermal source and maximize conversion efficiency. Open thermal systems designed to recover waste heat require a trade-off between high power density and minimal operating cost. Spectral control options are presented to meet the different end goals of the two systems.
